Video formats• When we are using Final Cut, we must

remember to use the correct number of pixels for the video format chosen in our original setup.

• Specified as (W x H), the various formats are:– NTSC D1 (720 x 486) normal – NTSC D1 (720 x 486) widescreen – NTSC DV (720 x 480) normal – NTSC DV (720 x 480) widescreen – PAL (720 x 576) normal – PAL (720 x 576) widescreen

• We are using PAL, so we must remember to use W=720 and H=576

Using layers in Final Cut

Using layers in Final Cut• We have used layers in PhotoPlus and PhotoShop• Layers in Final Cut work in a similar fashion• Lets take some images from PhotoShop for use as

different layers in FinalCut

First, lets look at some still images in PhotoShop• Originally this photo 4288 pixels wide and 2848 pixels high• Below, we have modified the image size, to make it 720x576 • The result is a little distorted but good enough for now• We have saved it as a .psd file, called tree720x576.psd

Another still image in PhotoShop

• This file, justBart2.psd, contains Bart on a transparent background

Clips derived from each still image in FinalCut

• Clips derived from both .psd files in the Final Cut browser panel

Putting the clips in the timeline

• The photograph clip is in the timeline

The second clip in a higher layer• The Bart clip, with a transparent background, is in a layer on top of the photo layer• The Bart clip is longer than the photo clip, so ...

Matching the clip lengths

• ... so we drag the right-hand end of the Bart clip, to ...

Matching the clip lengths• ... to make it the same length as the photo layer• And, with the playhead at the last frame, we see Bart in front of the garden

Tweening the opacity of the Bart layer

• Choose the pen tool and ...

Tweening the opacity of the Bart layer• ... and, placing a keyframe at the left end of the upper layer, • drag the opacity line down to 0%

Tweening the opacity of the Bart layer• Also, place a keyframe at the right-hand end of the upper layer and • drag the opacity line up to ...

Tweening the opacity of the Bart layer• ... drag the opacity line up to 100%

Tweening the opacity of the Bart layer• Below, the sequence has been rendered and is being played• The playhead is roughly 25% into the sequence, so• ... the opacity of Bart is about 25% as well

Tweening the opacity of the Bart layer• Below, the playhead is roughly 60% into the sequence, so• ... the opacity of Bart is about 60% as well

Tweening the opacity of the Bart layer• Below, the playhead is at the end of the sequence, so• ... the opacity of Bart is about 100%

Exporting this as a QuickTime movie• Let's export this sequence as a QuickTime movie, so• ... that we can see its effect live

Exporting this as a QuickTime movie• The movie is called bartHauntingTheGarden.mov

Seeing the effect of what we have done

• Although the sequence was exported as a .mov file, the file has been recoded to a .flv file to make it more practical for use on the web
