Exporting a Self-Contained Movie Without Recompressing the Media
If you choose to export a self-contained movie, you have the option to not recompress
the media in your clip or sequence. If you deselect the Recompress All Frames option
and choose Current Settings from the Setting pop-up menu, Final Cut Pro simply copies
frames from existing media files into the new file with no recompression. This is a
convenient way to export your media without subjecting it to recompression artifacts.
However, any media that must be created from scratch, such as a transition between two
media files, must be recompressed.
Important: The option to turn off recompression is unique to the Export QuickTime Movie
command and the Batch Export command. If you choose the Export Using QuickTime
Conversion command, every frame is always recompressed.
Determining Processing Color Space During QuickTime Movie Export
The color space (RGB or Y
′
C
B
C
R
) used for processing during QuickTime movie export
depends on what you select before exporting:
• A sequence in the Browser, the current sequence in the Timeline, or a sequence clip: Color
space is determined by the settings in the Video Processing tab of the Sequence Settings
window.
• A clip in the Browser or Viewer: Clips in the Browser or Viewer do not have video
processing settings in the way that sequences do. When a clip’s media file and export
codec both support Y
′
C
B
C
R
color space, the clip is processed using Y
′
C
B
C
R
color space.
For example, if you export a DV clip in the Browser to a DVCPRO HD QuickTime movie,
Y
′
C
B
C
R
color space is used because both the original and exported formats support this
color space.
If any step of processing requires RGB processing (such as effects or the source or
destination codec), the export happens in RGB color space. This is true even if the
destination codec uses Y
′
C
B
C
R
color space.
Exporting a QuickTime Movie File
You can export a QuickTime movie from three kinds of selections:
• A selected sequence in the Browser or the current sequence in the Timeline
• Media between a sequence’s In and Out points
• A selected Browser clip
To export a QuickTime movie from a sequence
1 Select a sequence in the Browser, or open a sequence in the Timeline.
2 Choose Sequence > Settings.
The Sequence Settings window appears.
