Apple Final Cut Pro 7 - Manual (Page 1875)

QuickTime Video Settings for Sequences
Final Cut Pro uses the built-in QuickTime architecture of Mac OS X to decompress, render,
and output video from your sequence. Since capturing is also handled by QuickTime,
QuickTime video settings are explained in more detail in
“QuickTime Video Settings for
Capture Presets.”
Settings in the
General tab
• Compressor: Choose a codec that matches the format of your media files. Any media
file in your sequence that doesn’t use the codec specified here must be rendered.
• Quality: Enter a percentage or adjust the slider to set the image quality of the codec.
Some third-party video interfaces may recommend specific quality settings.
• Advanced: Click this button to set additional QuickTime video settings. For detailed
information, see “Advanced QuickTime Video Settings for Capture Presets.”
Note: The alpha channel in codecs such as Animation and Apple ProRes 4444 is optional.
If you modify the sequence settings to use one of these codecs, the alpha channel may
not be automatically enabled. For more information, see
“Confirming Alpha Channel
Status.”
Confirming Alpha Channel Status
If your workflow involves adding or removing an alpha channel, be sure to double-check
the Depth setting for the alpha channel status.
To confirm the alpha channel status in sequence settings
1 Choose Sequence > Settings, then click the General tab.
2 In the Compressor pop-up menu, choose the alpha channel–compatible codec (Animation
or Apple ProRes 4444).
3 Click Advanced to open the Compression Settings dialog.
