Introduction

In a big budget Hollywood movie, lots of people are assigned to make sure they get the audio right.

It is hard to get good audio during post-production if you do not record good audio during production.

Give the audio priority during post-production.

Understanding Audio Principles

Multiple audio tracks allow you to work on each part individually without affecting the other parts.

Audio sweetening adds the final touches to any video you make.

Music can help create a mood for the film. Sound effects draw the audience into the experience

and make it real.

Working with Final Cut Express

If you record audio when you shot your video, the audio is captured at the same time. The audio is then added to the Timeline when you add the video.

The audio automatically is added to tracks one and two.

The default sequence settings in FCE include two video tracks and four audio tracks (two for dialog and two for music).

Working with Final Cut Express Adding Audio Track to the Timeline

It is easier to work with the default four audio tracks and add new tracks only when absolutely necessary.

On the Timeline, the green Audible button allows you to hear what is in the track. If you click it, the button turns gray and the track is muted.

Source buttons allow you to decide which Timeline tracks the audio (or video) will go into.

By default, the left Source channel will go into track A1, the right Resource channel will go into track A2.

Working with Final Cut Express Resynching Video and Audio

Audio synchronization, or audio synch, is when the sound matches the action.

Audio is out of synch is when a character’s lips move, but the sound doesn’t match the lip movement.

To keep the audio linked to the video, make sure the Linked Selection button is selected.

Working with Final Cut Express Import an Audio File From a CD

Music from a CD does not need rendering in FCE, while an mp3 or similar type of file needs rendering before you can work with it.

Working with Final Cut Express Adding Audio In and Out Points

Sometimes you don’t want to add the entire audio clip to the Timeline window.

You can create an in and out point and add the clip to the Timeline window.

Working with Final Cut ExpressAdd an Audio Clip to the Timeline

Once you add the audio file to the browser it is a project file you can use, but it must be added to the Timeline window in order for it to be part of the edit.

Working with Final Cut ExpressAdjusting Audio Levels

Audio tracks that play at the same time are heard at the same time.

Adjusting the audio levels means to change the volume for each track.

Drag the slider to the right increases the volume. Drag to the left to lower the volume.

Working with Final Cut ExpressAdding Keyframes to the Audio Level Overlay

Keyframes identify a specific position in the Timeline to start and end a level change.

Click the pink audio level overlay line with the Pen Tool. A diamond shape (keyframe) appears.

Drag the diamonds to adjust the audio volume at that point in the timeline.

Working in Adobe Premiere Elements: Importing Audio

Some downloaded music from iTunes or another online music source cannot be played back in Premiere Elements.

Music from a CD will need to be ripped using ripping software such as Windows Media Player.

Remember to respect copyright.

Working in Adobe Premiere Elements Adjusting the Volume From the Timeline

Audio with two tracks is imported into a single audio track.

Audio in more than one channel allows you to work with one channel at a time.

You cannot adjust anything in an audio clip until the clip is added to the Timeline window.

Summary

Finished audio includes dialog, music, and special effects. It is possible to work with each audio element by loading each one into an audio track so each can be worked with separately.

You can add additional audio tracks to a Timeline in order to add the separate audio elements.

Audio files can be imported into Final Cut Express and Adobe Premiere Elements.

The audio level of audio clips can be adjusted in order to make the audio volume louder or softer. Levels can be adjusted for the entire clip, or adjusted for only segments of the clip.

Summary (continued)

Sections of the clip can be adjusted by the use of keyframes.

Transitions can be used to smooth the change between audio clips.

Audio also can fade in and fade out. An audio fade in and fade out is a normal transition in Final Cut, but is added through the properties window in Premiere Elements.
