What’s New for Release 8.1

This section lists the new hardware and features for Media Composer

Release 8.1 for the Macintosh operating system.

New Hardware for Release 8.1

Media Composer Release 8.1 for the Macintosh operating system

supports the Meridien™ video subsystem on the Power Macintosh® 

G4 platform. For information about hardware and software

requirements, see “Hardware and Software Requirements” on page

10.

The Power Macintosh G4 system provides slots for the following

 boards:

• Apple graphics board

• Avid PCI Extender host interface board

• Keyspan SX Pro four-port serial board for deck control

nIncluding the serial board in the system configuration prevents the use of ICE

PCI boards. The serial board corrects an infrequent and intermittent system

hang during batch digitizing. Avid is actively working on a solution to

correct the system hang and to eliminate the use of the serial board. For

information about the serial board, see “Hardw are Confi gurat i on Change”

on page 67 .

The Avid PCI Extender provides six usable slots for the

Media Composer system.

The Power Macintosh G4 system uses universal serial bus (USB)

devices. There are two USB ports on the back of the Power Macintosh

G4. A seven-port USB hub attaches to one of the USB ports.

Avid supports the following USB devices:

• A USB floppy drive

• A USB-to-MIDI connector for fader connections (there is no MIDI

connector at the rear of the G4 system)

• A USB keyboard with a USB mouse that connects to the keyboard

For configuration information, see the Avid Composer Products Setup

Guide.

n  Avid Technology does not support additional devices on Apple’s Ultra SCSI

bus.

About the USB DevicesThe Avid Composer Products Setup Guide describes how to connect the

USB devices. This section covers additional information about the USB

devices.

n The USB technology is rather new to the marketplace. While it offers some

major benefits in terms of connectivity and choice of peripherals, Avid has

experienced some intermittent problems with some USB devices. Avid is

continuing to work with Apple and a number of USB peripheral vendors toimprove overall USB reliability.

Connecting the USB-to-MIDI Converter

To reduce the traffic on the USB bus, only connect the USB-to-MIDI

converter if you need to use the JL Cooper FaderMaster Pro™ fader or

the JL Cooper MCS-3000X fader.

Connecting the Avid Application Key

The Avid Composer Products Setup Guide states that the Avid application

key (dongle) connects to the keyboard. If your site is ESD sensitive,

you should connect the Avid application key to a USB port on the USB

hub.

About the Two-Button Mouse

The Media Composer system ships with a two-button USB mouse.

Media Composer Release 8.1 does not support the right mouse button

n

If you install the Macally software you cannot shuttle or scrub with the

mouse.

USB Mouse Not Responding

If your Avid system is not used for a period of time (approximately

1 hour), the mouse might not respond when you move it. If this

happens, disconnect the mouse cable from the keyboard and then

reconnect it.

n You can perform this procedure with the Media Composer application open

and the Macintosh turned on.

Changing USB Devices

To change a USB device:

1. Exit the Media Composer application.

2. Change the USB device.

3. Restart the Macintosh system.

4. Start the Media Composer application.

Dual Streams of Uncompressed Video

Media Composer Release 8.1 running on a Power Macintosh G4 withthe Meridien video subsystem supports dual streams of

uncompressed video. For information about the drive striping

requirements, see Table 11 on page 52.

Setting Deck Preferences for Digital Cut

Table 6-2 in the Avid Media Composer User’s Guide describes the Deck

Preferences options. “Poll deck during digital cut” is a new option for

this release.

The “Poll deck during digital cut” option is selected by default.

During a digital cut, if this option is selected, Media Composer checks

the deck for the current timecode and displays it in the timecode

window of the deck controller.

If you see degraded image quality on your digital cut (particularly

visible as noise during black), deselect this option and rerecord the

digital cut. With the option deselected, the timecode display in the

deck controller will not update for the duration of the digital cut. Thedigital cut to tape is frame accurate even without displaying the

timecode in the Timecode window of the deck controller.

n If a complex sequence successfully plays, but you receive video underrun

errors during a digital cut, deselect the “Poll deck during digital cut” option

and rerecord the digital cut.

Using Media Composer with Avid Unity MediaNet

Avid Unity™ MediaNet allows you to share bins and projects across

the network. When you place your bins and projects on Avid Unity

MediaNet workspaces (drive volumes), several users can work on the

same project at the same time.

Each user can perform tasks from his or her own Avid system. The

Media Composer application provides a simple locking mechanism tohelp you keep track of who is currently working in a bin. The method

allows one writer access and multiple readers access to a bin.

For information about sharing bins and projects, see “Sharing Bins

and Projects on Avid Unity MediaNet” on page 68.

Changing the Memory Allocated to the Application

When you install Media Composer Release 8.1, the “Minimum” and

“Preferred” default memory settings for the application are each

147,900 KB.

n If you have a system that has less than 256 MB of RAM, change the default

memory settings for Release 8.1 back to their original “Minimum” and

“Preferred” values.

You might need to increase the Preferred size if you are working on

large projects with Media Composer.

If you increase the amount of memory allocated to the application,

make sure to leave enough memory to run the Macintosh operatingsystem and other applications, such as EDL Manager, AvidNet, and

Help. The operating system’s need for memory is dynamic; therefore,

the operating system might require more memory when running

certain processes.

To change the amount of memory allocated to the application:

1. Click the application icon to highlight it.

2. Choose Get Info from the File menu.

Obtaining the Macintosh Operating System

The Avid Media Composer Release 8.1 for the Macintosh Operating

System CD-ROM does not include a copy of the Macintosh OS

software. A separate Macintosh CD-ROM contains the OS. Two

methods are available for getting a newer version of the Macintosh OS

• Install the software from the Macintosh CD-ROM. You receive this

CD-ROM when you purchase a new Power Macintosh. Follow the

instructions in “Guidelines for Installing the Macintosh

Operating System” on page 24 of these release notes.

• Obtain the OS from an Apple Computer dealer. Copies are

available on CD-ROM.

Obtaining the Macintosh OS ROM Update

You can download the Mac OS ROM update from the Apple Web site,

if you need to update the version of the Mac OS ROM. For information

about the ROM version required for Media Composer Release 8.1, see

“Required Macintosh Operating System and ROM Versions” on

page 10.

Verifying That the Font Manager Update File Is Installed

The Macintosh OS 8.6 Font Manager might create corrupt FOND

resources or corrupt fonts. When this occurs, fonts with corrupted

resources cannot be moved.

Verify the Macintosh system running OS 8.6 has the Font Manager

Update file in the Extensions folder. If the file is missing, you canobtain the file from an Apple Computer dealer.

Choosing the Avid Drive and Restarting

If you changed your startup disk to install the OS, restart the

Macintosh from the internal hard drive, using the following steps:

1. Choose Startup Disk from the Control Panels on the Apple menu.

2. Select the internal hard drive (usually the Avid drive).

n The internal hard drive might be named Macintosh HD.

3. Close the window and restart your Macintosh.

The system starts up from the Avid drive.

Installing Software Drivers

The software drivers for the USB devices and serial board ship

separately from the Avid CD-ROM installer. If needed, you must

install the USB device drivers and serial board driver before you

install the Media Composer application.

Install the software drivers for the USB devices and serial board in thefollowing order:

1. Serial board (drivers are preinstalled)

2. USB-to-MIDI connector (if needed)

3. USB floppy drive

n Do not install the Macally mouse software drivers. If you install the Macally

software drivers, you cannot shuttle or scrub with the mouse.

n If the devices are connected to the Avid system before the software drivers are

installed, you will receive error messages. To eliminate the error messages,

install the software drivers and restart the Avid system.

Installing the Media Composer System Software

You can install Media Composer on a Power Macintosh G4 system that

has Meridien hardware, or you can upgrade to Media Composer

Release 8.1 from a system running Media Composer Release 8.0. For a

list of supported systems, see “Required Macintosh OperatingSystem and ROM Versions” on page 10.

Checking Virtual Memory and Cache Size

Before you install the Media Composer application, check virtual

memory and cache size. You must turn off virtual memory and set the

cache size to run the Media Composer software. If you have notalready done so, do the following:

1. Choose the Memory Control Panels from the Apple menu.

2. Set the Cache Size to 128K.

3. Turn off virtual memory and close the window.

4. Restart your Macintosh.

Disabling Hard Disk Sleep Mode

Before you install the Media Composer application, disable hard disk

sleep mode. The Macintosh OS has an Energy Saver control panel that

can put your system, display, or hard drives into Sleep mode when

you don’t use them for a designated period of time. If the internal hard

drive goes into Sleep mode while your Media Composer system is

running, the system might hang or crash.

To disable the hard disk Sleep mode on your Media Composer system,

choose Energy Saver from the Control Panels list, and set the option

“Put the system to sleep when it’s inactive for” to Never.

Preliminary Information

Verify that the version of the Macintosh OS is a supported version, see

“Verifying the Macintosh Operating System Version” on page 22.

New systems are shipped with the current version of the Macintosh

OS installed, but you should still verify that you have the currentversion.

c This installation overwrites any prior release of Media Composer

software that is loaded. If you prefer, you can save the old release of

the Media Composer system software by renaming the folder on the

Avid drive that contains the application. This also saves the old

Settings and SupportingFiles folders.

n If you have problems installing the software when using these instructions,try turning off any virus-checking extensions or other system-monitoring

software running on your Avid system. Use the Extension Manager to turn

off these applications, and then repeat the installation process.

 After installing the software, use the Extension Manager to turn on any

virus-checking extension or other system-monitoring software that you

normally run on your Avid system, and restart the system.

Installation Procedure

Before you install Media Composer, make sure the software for the

USB devices and serial board are installed, see “Installing Software

Drivers” on page 25.

n

Do not install the Macally mouse software.

To install Media Composer:

1. Restart your Avid system.

2. Quit any applications that open automatically at startup.

Running Updaters

If you are upgrading a Macintosh G3 or 9600 system to

Media Composer Release 8.1, you might need to update the various

firmware by running the updaters.

The updaters are:

• ASTFlasherPro updates the firmware on the Meridien display

controller board. Double-click ASTFlasherPro in the

Utilities/AvidSystemTest folder to run the updater.

• VideoIOUtil updates the firmware on the Meridien serial digital

video I/O board. Double-click VideoIOUtil in the

Utilities/AvidSystemTest folder to run the updater. You must turn

the power off and on to the Meridien I/O box after you run theVideoIOUtil updater.

n ExpressPCI_UL2D updates the firmware on the dual-channel SCSI LVD

board. Only run the ExpressPCI_UL2D updater when you are moving the

dual-channel SCSI LVD board to a G4 system. If you plan to move the board

to a G4, you must run the ExpressPCI_UL2D updater before you move the

board to the G4. Media Composer Release 8.1 functions with the current

 firmware on the dual-channel SCSI LVD board in your G3 or 9600 system.

 After you run ExpressPCI_UL2D, you need to turn the power off and on to

the Avid system.

Test Patterns

Test patterns are no longer located in the Goodies folder. They are now

located in the SupportingFiles folder and should be imported with 601

video levels.

Fibre Channel Configurations

If your Avid system is configured with a Fibre Channel board and theAvid Fibre Channel driver is enabled, make sure:

• There are drives connected to the Fibre Channel board and they

are turned on.

• The connection is on for Avid Unity MediaNet configurations.

The Fibre Channel driver searches for drives. If none are connected to

the Fibre Channel board or if the Avid Unity MediaNet connection is

off, the performance of Media Composer is affected.

Disable the Fibre Channel driver if no drives are connected to the Fibre

Channel board or if the Avid Unity MediaNet connection is off:

1. Quit Media Composer.

2. Choose Control Panels from the Apple menu.

3. Choose Extensions Manager.

The Extensions Manager window opens.

4. Duplicate the current set of extensions and rename the file.

Automation Gain Tool Enhancement

The Automation Gain tool contains an OMS® Active indicator. If you

have the OMS software installed on your system, the indicator will be

green to indicate that OMS is in use.

Using Media Composer with FilmScribe or EDL Manager

If your Avid system includes FilmScribe or EDL Manager, and your

projects contain complex sequences or large bins, you might need to

increase the minimum memory size for FilmScribe or EDL Manager.

For information about changing the memory size, see “Changing the

Memory Allocated to the Application” on page 14.

Calibrating Audio Hardware

You can now use the Audio Settings dialog box to change your default

audio hardware calibration. The application’s default audio hardware

calibration is set to –14 dBFS and new audio I/O devices (888 I/O™)

shipping from Avid are calibrated to –14 dBFS. If you change the

application’s default, you must recalibrate your audio I/O device tomatch.

The Avid application’s audio hardware calibration setting must match

the calibration of your audio I/O device. The Avid application cannot

determine the calibration of your audio I/O device. If you are using

older audio hardware or if you are unsure of your audio device’s

calibration, you might need to change the calibration of your audio

I/O device.

If the application’s hardware calibration setting value does not match

the calibration of your audio I/O device, the analog VU (volume unit)

scale in the Audio tool will display incorrect values.

Page 57: Avid Media Composer 8.1.0 User Guide

8/10/2019 Avid Media Composer 8.1.0 User Guide

http://slidepdf.com/reader/full/avid-media-composer-810-user-guide 57/93

57

To synchronize the audio hardware calibration setting with the audio

I/O device, do one of the following:

• Change the calibration of the audio I/O device to match the

application’s hardware calibration setting value.

• Change the application’s hardware calibration setting value to

match the calibration of the audio I/O device.

For procedures on how to calibrate the audio I/O device, see

“Calibrating Input Channels of the Audio I/O Device” on page 59  

and “Calibrating Output Channels of the Audio I/O Device” on

page 61.

n Calibrating the audio I/O device requires a sine wave generator and a

screwdriver.

For example, if your audio I/O device is calibrated to –14 dBFS, you

can set the application’s hardware calibration setting value to

–14 dBFS. After you change the application’s hardware calibration

setting value, the following settings also change to match:

• Reference Level in the Set Reference Level dialog box (Peak Hold

pop-up menu — Audio tool)

• Calibration Tone in the Set Calibration Tone dialog box (Peak Holdpop-up menu — Audio tool)

more information on time-base correctors, contact your Avid reseller.

Green Line in VHS Video

Some VHS tape decks do not output the full 240 lines of video

normally included in the VHS format. As a result, after you digitize

from a device such as a VCR, a green line might appear at the bottom

of the monitors in Media Composer.

This line is at the bottom of the visible area of the picture, and is not

seen in a standard consumer monitor in most cases. If you use the

video in a circumstance in which the line is visible, you can remove it

 by cropping the bottom edge of the picture.

n For more information on cropping, see the Avid Media Composer Effects

Guide.

Changes to the Timing of Video Signals

Genlocking is now different from that of previous Avid video-based

editing products for Macintosh systems. The system’s timing is now

modeled on that of a VTR; it uses only a single time-base that is

switched between input and output.

Note the following operation modes:

• Timing during video capture: When capturing (that is, recording)

an input video signal, sync timing will be derived from that input

signal. The timing of the captured video and audio will be correct.

The green Video Sync light on the Meridien I/O box will be on

when synchronization to that signal is attained.

Passthrough video outputs: During capture, timing of the

recorded media files will be correct. The timing of the passthrough

output signals, however, will be correct relative to themselves but

will have slight delays relative to the input time-base. In

Page 64: Avid Media Composer 8.1.0 User Guide

8/10/2019 Avid Media Composer 8.1.0 User Guide

http://slidepdf.com/reader/full/avid-media-composer-810-user-guide 64/93

64

particular, the composite output will have one line of additional

delay, due to comb filter operation compared to Serial Digital and

other analog modes. This is normal operation.

Passthrough audio versus video: During capture, the recorded

video and audio will be correctly timed. However, since

passthrough audio does not undergo delay, the previouslydescribed video delays will exist relative to the undelayed audio.

In media files, the video and audio will be synchronized.

• Timing during capture for audio with no video present:  Timing

will be derived from any signal present on the REF input. If no

reference signal is detected there, the timing will automatically

switch to an internal, free-running, highly accurate time-base and

the green Video Sync light will not be lit.

c If you are digitizing audio only from a source that uses REF IN (with

black burst, for example) on the Meridien I/O box for sync, the

system will change the timing reference to the video input signal

when the option “Always display incoming video in the

Client monitor” is selected in the Digitize Settings dialog box. To

avoid losing the REF IN sync source, deselect this option before

capturing audio only.

• Timing during playback: In all playback modes, the video timingis derived either from the external genlock source (the REF input)

or from the accurate internal time-base. If a composite reference

signal is present on the REF input, that signal will be used for

deriving genlock and system timing. The green Video Sync light

will be lit. If no lock is detected to a signal on the REF input (or if

no signal is present), the system will automatically switch to its

internal timing source and the Video Sync light will not be lit.

n For additional information on digitizing with consumer or prosumer video

decks (such as VHS, Hi-8, and some ¾-inch decks), see “Limit at i on When

Using Consumer Decks or D ecks Wi t hout Time-Base Correct ors” on

page 62 .

Simultaneous Output Modes

The video outputs are all simultaneously active with one exception:

only one of the S-Video or Analog Component outputs can be active at

the same time. You select the one you want with the Video Output

tool.

Genlock Timing Adjustments

Adjusting the genlock timing to the house reference at switchers or

routers can be done only in Playback mode. With previous Avid

implementations for Macintosh systems, this could have been done in

Passthrough mode. You could either record your own test signal and

then play it back; alternatively, you could put out a test pattern from

the application’s Video Output tool and use that for doing the usualHPHASE and SCPHASE adjustments.

Only one format of the active outputs can be accurately genlocked at a

time. Since there is only a single adjustable output time-base, you

simply set the genlock parameters for the critical output that is the one

you choose to genlock. For most applications, this will be either the

composite or the SDI outputs.

All the video output signals — Composite 1, 2, and 3, Serial Digital (ifthat option is on your system), and component or S-Video — are

synced to the same time base, and hence are synced to each other.

However, they all have slightly different internal delays. This means

that you can set the HPHASE so that only one — the one you choose

— will be exactly synced to an external genlock reference. The other

output signals will be properly timed relative to themselves but will

not be precisely genlocked.

Operation of the Green Video Sync Light on the Meridien I/O Box

The green Video Sync light is lit whenever the timing is successfully

locked to either REF or to the video input signal. If the green light is

off, the timing is being obtained from the internal, free-running time

 base.

Black Levels When Outputting SDI from NTSC Input

When video input is NTSC with setup and video output is SDI (which

does not use setup), the half lines at the top and bottom of the analog

frame will contain blanking and black setup at two different levels

(zero and 7.5 IRE).

When the input video’s black at setup is properly adjusted to

correspond to digital 16, the blanking level will correspond to

approximately digital 1. This can result in video levels in the SDI

output that are below black in several places:

• The first half of the top half line (line 283) will be below black, at

approximately digital 1.

• The last half of the bottom half line (line 263) will be below blackat approximately digital 1.

• The horizontal blanking edges can have pulses that go down to

near digital 1 at the left and right edges of the image. This is due to

the fact that the 720-pixel ITU-R 601 frame extends beyond the

edges of the NTSC setup pedestal by a few pixels. These few pixels

will be at approximately the blanking level (digital 1), while the

rest of the horizontal line will be at black at digital 16.

When the video is played back as SDI, there will be negative pulses

that appear for this reason. If the output is NTSC with setup, these

pulses will be canceled out. If, however, the SDI output ultimately

goes to an NTSC-EIAJ encoder, these pulses will be below blanking.

This latter problem is common to other equipment as well and is a

property of the difference between the black levels of these three

formats.

Setting Up the Edit Monitor

Make sure the color depth for the Edit monitor is set to Millions. For a

procedure on setting up the Edit monitor, see the Avid Composer

Products Setup Guide.

Documentation Changes

This section describes changes and additions to the Media Composer

Release 8.0 documentation.

Hardware Configuration Change

A change to the hardware configuration was made after the printing of

the Avid Composer Products Setup Guide.

The hardware change is:

• The USB-to-serial converter is not being used. This device is

described in the Avid Composer Products Setup Guide as connecting

to a port on the USB hub.

• A Keyspan SX Pro four-port serial board was added to the

peripherals kit. The serial board is normally located in PCI slot 3 of

the G4 system, see Figure 1.

Page 68: Avid Media Composer 8.1.0 User Guide

8/10/2019 Avid Media Composer 8.1.0 User Guide

http://slidepdf.com/reader/full/avid-media-composer-810-user-guide 68/93

68

You must load the serial converter software prior to loading and

executing the Avid software, see “Installing Software Drivers” on

page 25.

Figure 1 Serial Board Location

Connecting the USB Devices and Installing the Drivers

The Avid Composer Products Setup Guide indicates that you should

connect the USB devices before installing the device drivers. This is

incorrect and will cause error messages when you turn on the Avid

system. To eliminate the error messages, install the software drivers

and restart the Avid system.

Sharing Bins and Projects on Avid Unity MediaNet

Avid Unity MediaNet allows you to share bins and projects across the

network. When you place your bins and projects on Avid Unity

MediaNet workspaces (drive volumes), several users can work on the

same project at the same time.

69

For example, an editor can create sequences in one bin while an

assistant redigitizes media in another bin. At the same time, other

users can add audio effects or titles to other bins in the project.

Each user can perform tasks from his or her own Avid system. The

Media Composer application provides a simple locking mechanism to

help you keep track of who is currently working in a bin. The method

allows one writer access and multiple readers access to a bin.

c The lock does not prevent you from deleting the media in a locked

bin if you have write access to the workspace. It ensures only that

you don’t overwrite changes to the bin.

Mapping Workspaces on the Avid Unity Network

For information on mounting workspaces, see the Avid Unity MediaNet

 for Macintosh Clients Quick Start Card. These instructions assume that

Avid Unity MediaNet is up and running. For details on Avid Unity

MediaNet, see the Avid Unity MediaNet Administration Guide.

Sharing Methods

Before you begin copying or creating bins and projects on an

Avid Unity MediaNet workspace, you need to determine the sharing

method you will use for the project.

Shared Bins

When you use this method, you store the project on your Avid system

and store bins and media files on the shared workspace. This method

allows users in a shared environment to share only selected bins with

other users.

The Media Composer application uses the following methods to

identify the shared bins:

• Stores the bin in a Unity Bins folder in the Project window. This

folder is similar to the Other Bins folder.

the Avid system that currently has the bin locked.

• Uses bold text to identify bins that are locked by other users.

Shared Bins and Projects

If you share bins and projects, you create and store the project folder

and bins on the shared workspace (or copy an existing project, bins,

and the related media files). The Media Composer application uses the

following methods to identify information from each Avid system

using the shared workspace:

• Creates a project folder for each Avid system that accesses the

project. Media Composer adds the Avid system’s computer name

to the folder name to create a unique name and stores any project-specific information in the folder. This mechanism prevents users

from overwriting the project-specific data for other users.

The folder is similar to the folder created when you choose New

Folder from the Project Window Fast menu. For more information,

see “Managing Folders and Bins” in the “Working with the Project

Window” chapter of the Avid Media Composer User’s Guide.

• Displays an extra column in the Project window that identifies the

Avid system that has the bin locked.• Uses bold text to identify bins that are locked by other users.

• Creates a folder at the top level of the shared workspace called

Unity Attic. This folder contains backup files for each project on

the shared volume.

n Depending on the number of users sharing a workspace, you might want to

increase the number of files that the Media Composer stores in the Attic folder

(use the Bin Settings dialog box).

When a bin is unlocked, you have permission to make changes.

You should not make changes to a locked bin. See “Restrictions

and Limitations for Locked Bins” on page 74.

n The Bin Lock Status button does not appear if the bin is not on the

 Avid Unity MediaNet environment.

Working with Locks

Media Composer uses a simple locking mechanism to help you keep

track of who is currently working in a shared bin. This allows onewriter access and multiple readers access to the bin.

Default Locking Mechanism

The user who opens the bin first gets the lock and obtains write access

to the bin. Media Composer uses bold text in the Project window to

identify bins that are locked by another user. When the person who

owns the lock closes the bin, it becomes available for another user to

open and take the lock.

If one user has the lock and second user has the same bin open, when

the first user closes the bin, the second user must close and reopen the

 bin to get the lock.

Bin Lock Status button:

8/10/2019 Avid Media Composer 8.1.0 User Guide

http://slidepdf.com/reader/full/avid-media-composer-810-user-guide 74/93

74

You can click the Bin Lock Status button in the bin to view a history file

that shows which Avid systems and users have modified the bin.

To open a bin without taking the lock, Option+double-click the bin in

the Project window.

Overriding the Default Locking Mechanism

You can instruct Media Composer to keep a bin locked even after you

close it.

To permanently lock a bin:

1. Select one or more bins in the Project window.

2. Choose Lock Project Bin from the Clip menu.An asterisk (*) appears next to the user name in the Project

window. In this case, the bin remains locked even after you close

it.

To unlock the bin, click the bin in the Project window and choose

Unlock Project Bin from the Clip menu.

Restrictions and Limitations for Locked Bins

The following restrictions apply to bins locked by another user:

• You cannot select a locked bin for operations such as digitizing,

title creation, and importing. This helps to minimize the problems

of modifying a locked bin.

• You cannot drag to a locked bin.

• If you drag from a locked bin to an unlocked bin, theMedia Composer application will create a duplicate (not a copy) of

the selection in the unlocked bin. The original item is not removed

from the locked bin. This operation is the equivalent of

duplicating a selection and then dragging the duplicate to another

 bin.

Page 75: Avid Media Composer 8.1.0 User Guide

8/10/2019 Avid Media Composer 8.1.0 User Guide

http://slidepdf.com/reader/full/avid-media-composer-810-user-guide 75/93

75

• You cannot move a bin that is locked by another user.

• If you modify a locked bin, the Media Composer application will

not let you save the bin to the same name, but it will allow you to

save the bin to another name. However, this causes duplicate bin

IDs and might cause system-level conflicts with the contents of the

two bins. The Media Composer application will see the duplicatesof the contents of these bins and will resolve the conflicts by

newest modifications (this might not be desirable behavior).

You should avoid creating duplicate bins by modifying a locked

 bin. If you do create a duplicate bin in this way, you should

manually merge the changes into the original bin and delete the

duplicate bin.

c The lock does not prevent you from deleting the media in a lockedbin if you have write access to the workspace. It ensures only that

you don’t overwrite changes to the bin.

AVIDdrive Utility 2

The following features and support have been added to AVIDdrive™ 

Utility 2 since the manual was printed:

1. AVIDdrive Utility 2 (ADU 2) supports the Desktop FieldPak® 

Adapter.

When you use ADU 2 with the FieldPak Adapter, you can move

the mounted FieldPak to a Raw state (no file system) and then

place a Macintosh file system on the FieldPak. This allows you to

use the FieldPak like any other Macintosh hard drive (mount and

unmount it). Later, when you move the FieldPak back to the

camera, you must reinitialize the FieldPak for use with the camera

2. You can use AVIDdrive Utility 2 to erase and partition Avid rS

MediaDrives, iS MediaDrives, all Pro MediaDrives, and Avid

MediaDock Shuttle LVD packs.

3. You can no longer create 2-GB partitions. A 4-GB partition is the

smallest partition allowed by AVIDdrive Utility 2. If you have a

Page 76: Avid Media Composer 8.1.0 User Guide

8/10/2019 Avid Media Composer 8.1.0 User Guide

http://slidepdf.com/reader/full/avid-media-composer-810-user-guide 76/93

76

2-GB drive, you must choose maximum size when asked for the

size of the partition.

c Repartitioning your drive will overwrite data currently on the drive.

4. You can use a SCSI LVD board to perform 4-way and 8-way

striping.

n For striping information, see “D ri ve St ri pi ng Confi gurat i ons” on page

47 .

5. When ADU 2 first scans the SCSI bus, it checks each drive for the

latest driver. If a drive does not contain the latest driver, the

software asks if you want it updated. If you click OK, the software

places the driver into the same partition, so it will not rewrite ormove other files or directories.

6. The buttons that point to Norton Utilities® and to Disk First Aid

have been removed. You should now use the DiskWarrior

diagnostic. DiskWarrior software and a CD-ROM that contains the

online manual ships with your system.

7. The Save Report feature has added more information. The device

list now prints out the vendor, model and revision of the SCSI

 board that connects the SCSI devices.

Fixed Bugs in Release 8.1

You can automatically start DiskWarrior from

AVIDdrive Utility 2 Version 2.2. 

Auto-save now functions correctly when you start Media Composerby double-clicking on a project.

You can move media files from Avid Symphony Release 2.1,

Media Composer Release 9.1 (Windows NT), Film Composer® 

Release 9.1 (Windows NT), or Avid Xpress Release 3.1

(Windows NT) to a Media Composer Release 8.1 (Macintosh)

system, and then consolidate the media without receiving errors.

An undersized QuickTime file will now resize on import when the

Maintain and Resize option is selected.

When you choose a compression setting in the Compression tool,

the setting remains set until you change it in the Compression tool.

Setting the Preroll option in the Automation Gain tool allows

recording to start at the set preroll.

You can scrub audio-only clips by using the step (jog) buttons or the

mouse without receiving an unmapped memory exception.

In previous releases, MediaLog might put 30 fps in the CFPS column

when a PAL deck was attached. This would in turn prevent batch

digitizing from the logged clips. This problem has been fixed.

In previous releases, you might receive an Access Violation error

message when renaming a media file. This problem has been fixed.

Page 81: Avid Media Composer 8.1.0 User Guide

81

In previous releases, you might notice noise in the Black signal

when performing a digital cut. This problem has been fixed with the

addition of the “Poll deck during digital cut” check box to the Deck

Preferences dialog box, see “Setting Deck Preferences for Digital

Cut” on page 9.

In previous releases, if you disconnected the application key

(dongle) from the ADB chain and restarted the Avid application, the

system might display an Assertion Failed error message. This

problem has been fixed. The system correctly displays a dialog box

stating that the application key is missing.

Starting Apple System Profiler from the Apple menu with the PCI

expansion chassis turned on no longer causes a fatal error.

Known Bugs

Audio

If you plan to use Pro Tools® on the same system as Media Composer,

note that Pro Tools uses different versions of the following files:

• DigiSystem_Init — stored in the Extensions folder

• Default AudioSuite Plug-Ins — stored in the DAE folder in the

System folder

If you plan to use Pro Tools on your Media Composer system, you will

need to keep separate copies of these files and copy them to the correctlocation before you start the application. For the default AudioSuite

Plug-Ins, you should keep separate copies of the entire DAE folder

(located in the System folder).

After you replace the files, you must restart the system for

DigiSystem_Init to take effect.

An exception error occurs when you play a group clip with an audiopan over the edit.

Audio fades do not get extracted from the OMFI file when pan/vol is

on the clip. When you import this OMFI file into another system,

the dissolve will be unrendered. You might want to perform an audio

mixdown of the clip before exporting.

Compatibility with Other Products and Releases

If you eject a local drive from a system that has Avid Unity

MediaNet volumes mounted, when you select Mount All from the

File menu, the following error message displays:

 Mac Error -65 (r/w requested for an off-line drive)

Page 83: Avid Media Composer 8.1.0 User Guide

Media from Media Composer Release 8.1 (this release) cannot be

brought back into Avid Symphony 1.0 and Avid Xpress Release 2.0.

You need to upgrade your Symphony system to Release 1.1v1 and

Avid Xpress to Release 2.1v1 or later.

Media from Symphony Release 1.0 and Avid Xpress Release 2.0 can be

 brought into Media Composer Release 8.0.

Media files can become temporarily hidden when moving projects

and media files from Macintosh to Windows NT systems. When you

move a project and media files from Media Composer (Macintosh

system) to Avid Symphony (Windows NT system), the directory on

the HFS volume can become corrupted when you start the Symphony

application. If this happens, the media files in the OMFI media file

folder will become hidden from the operating system.

Workaround: In this case, you should bring the drive back to the

Media Composer system and run the DiskWarrior application to

rebuild the directory structure on the drive. Then the media files

should reappear.

To avoid this problem, use the following method to transfer the files:

1. Copy the OMFI media files folder on the HFS volume to an NTFS

volume on the Symphony system.

2. Shut down the Symphony system, remove the drive, and restart

the system.

3. Start the Symphony application. It should recognize the OMFI

media files.

Symphony Releases 1.0 and 1.1 do not support 10:1 video resolution

Workaround: Redigitize at another resolution when bringing in media

to Symphony from Media Composer 8.1.

Consolidating Master Clips

Consolidated master clips have inaccurate locators.

Digitizing

Not all frames in the Timeline are updated after redigitizing a

sequence and the clips.

When batch digitizing, the digitize process might stop before

reaching the OUT point, but appear to continue past the OUT point.

The tape will continue running past the OUT point.

 When opening the Digitize tool you might receive an “Unmapped

Memory Exception” error.

When you use the function keys to digitize, press the F4 key to start

digitizing. This function was moved from the B key because of a new

feature that allows you to type clip names during digitizing. The

change to the F4 key allows you to type the letter B in clip names.

Switching input sources prevents the Waveform and Vectorscope

monitors from adjusting properly. If you have a bad signal coming in

through a Serial Digital Input (SDI) format and you switch the input

settings to a different format (Composite or Component), the

Waveform and Vectorscope monitors do not adjust properly to the

new signal.

Digitizing with Macrovision® copy-protected tapes causes sync

problems.

If the video input signal is interrupted, it is possible for the internal

Vectorscope monitor to display incorrect data once the signal is

restored. This does not affect the signal being digitized. The signal

Page 85: Avid Media Composer 8.1.0 User Guide

8/10/2019 Avid Media Composer 8.1.0 User Guide

http://slidepdf.com/reader/full/avid-media-composer-810-user-guide 85/93

85

could be interrupted when cables are disconnected, or when signal

generators or decks are turned off.

Workaround: Click the V button in the Digitize tool off and then back

on again, and the Vectorscope monitor should correct itself.

Editing

The display of accent characters (set from the Apple Key Caps

window) in the bin is different from the display in the Timeline.

Scenes and takes can get lost in scene pull lists whenever

overlapping names or numbers occur.

Dual-sided trim does not function with extend edit and sync locks

enabled.

The Reverse Match Frame function is not working correctly with

motion effects.

There might be a hue shift noticed in certain colors when Avid

graphics are being drawn on video. Since the graphics are notdisplayed during play, it will not affect the output of your digital cut

and will only be noticeable when parked on a frame. Examples of Avid

graphics include mark IN, mark OUT, and sawtooth marks denoting

the beginning or end of a clip.

Effects

The Matte Key effect might cause a slight luminance level drop tothe background media under the matte key.

The luminance level will drop slightly in non-real-time keys when

crop or position parameters are adjusted.

Page 86: Avid Media Composer 8.1.0 User Guide

86

When playing a sequence with a non-real-time transition effect that

is applied to a clip with a color effect, the Client monitor might

display a color shift.

If you move bins that contain paint and AniMatte effects to

Symphony Release 2.1 or Media Composer Release 9.1

(Windows NT system), and you modify the effects, you cannot move

the bins back to Media Composer Release 8.1 (this release). You will

receive an error message.

The 3D Drop shadows that travel independently of their object do

not play smoothly.

Borders on 3D PIP effects are not always equal.

The Stamp effect will not work on the first keyframe of an effect.

AudioSuite effect templates only work with the original master

clips.

Certain 3D effects display highlights and shadows as black and

white lines.

When you Option+drag to copy a title, 3D title, or a Matte Key effect

from a bin, the clip name will be missing.

Hardware

The 888 I/O audio meters do not always display accurately. Themeters could show a signal that is not present.

87

Help System

The Print Topic command generates an error message but works

correctly. On some systems, when you choose Print Topic from the

Contents tab of the Help Topics window, the system prints the topic

correctly but also displays a message that you have encountered a linkthat does not work. You can ignore the message.

Import and Export

The padding for sequential PICT files is wrong.

When you export an OMFI graphic to a drive with insufficient diskspace, the system freezes.

Workaround: Export to a drive with adequate storage space.

Batch importing a duplicate of a master clip causes the original

master clip to be offline.

Workaround: Unlink the duplicate before batch importing it.

When you export a file larger than 2 GB, a system error occurs. 

Workaround: Ensure that the file you are exporting does not exceed

the 2-GB limit. If the error occurs during a video mixdown, try to mix

down in smaller segments.

The position indicator will not be used if you export by pressing the

Option key and using the drag-and-drop method. Option+drag doesnot use the position indicator and will always use mark IN and mark

OUT, even if Use Marks is disabled.

Media Composer does not support QDesign Music audio. If you try

to import audio formatted with the QDesign Music codec, QuickTime

crashes.

Workaround: Choose to Import Video Only or cancel the import.

If you import an OMF composition with video media and change

the resolution on import, you might encounter problems if you

delete the media clip and then attempt to reimport the file to the

same bin. If you attempt to reimport the same file to the same bin (or

to a different bin while the first bin is open), the system imports the

composition but not the media.

Workaround: Close the bin, open another bin, and import the file to

the new bin. You can also try quitting and restarting theMedia Composer application and then reimporting the file.

If you set Autodetect Sequential Files to ON in the Import Settings

dialog box, folders ending in digits larger than 1 will not appear in

the Import Files dialog box.

Workaround: Set Autodetect Sequential Files to OFF in the Import

Settings dialog box, or rename folders so they do not end in digits

larger than 1.

Monitors

You cannot change the monitor resolution while Media Composer is

running.

Workaround: Quit the Media Composer application before changingthe monitor resolutions.

Titles

When saving a very complex rolling title, you might receive a

“MEM_OUT_OF_MEMORY” message.

Workaround: Try reducing the complexity of the rolling title.

When you import a Photoshop .psd title file, you receive an

“Exception: No Error” message. The file does not import.

Workaround: Save the Photoshop file as a PICT file when saving and

exporting from the Photoshop application.

In Transition Corner Display mode, extending and shortening a

dissolve effect on a rolling title might cause a BAD TIMINGmessage. This should not affect your work.

Editing or saving a large, multipage file can take a few minutes.

Playing a long, complicated, rolling title can cause an exception

error. 

Workaround: Try reducing the complexity of the rolling title.

You cannot revise a title after exporting it as OMFI Version 1 or 2.

In the Effect Editor, if the Acceleration category is set to 100 (fast),

dragging the scroll bar through the Timeline over a keyframe might

causes an error message.

Workaround: Acceleration is not recommended for rolling titles or

other DSK titles with vertical motion, due to anti-aliasing effects that

cause flicker.

When you import an OMFI 2.0 file with rolling titles, the icons for

the rolling titles are blank.

Some italic text in titles can become truncated.

Workaround: Click the Right, Left, or Center Justification buttons to

eliminate truncation of text. You might have to create several text

 blocks to resolve this problem with multiple lines of text in your titles.

Some 3D titles might not crop properly. The first letter of the title

might be clipped.

Workaround: Open the left crop bar and adjust until the first letter is

no longer clipped.

Mixing different fonts, different sizes, and different styles might

realign the vertical placement of a title.

Utilities

Media Composer does not support MSM media when you use OMF

utilities from Media Composer Release 7.1.
