Chapter 16 Exporting Sequences for DVD 221
III
When a movie or sequence with at least one chapter marker is exported, the exported
QuickTime movie has a text track, in addition to the video, audio, and timecode tracks.
This text track is automatically set up as a QuickTime chapter track. How this track is
used depends on the application you use to open the exported QuickTime movie.
 In QuickTime Player: A chapter track is visible from QuickTime Player as a pop-up
menu in the movie window. Choosing a chapter from this menu automatically moves
the playhead to that frame of the movie.
 In DVD authoring applications: Chapter markers are used by DVD authoring
applications, such as DVD Studio Pro and iDVD, to provide chapter navigation on
a DVD.
When you add chapter markers for use by a DVD authoring application, they are
subject to the following limitations:
 No chapter marker should appear closer than 1 second to the beginning or end of
your edited sequence.
 A chapter marker should be at least 1 second away from any other chapter marker.
 A maximum of 99 chapter markers can be placed within a single program.
 When exporting from a sequence, only sequence markers are exported; markers in
clips are ignored.
 When exporting a clip from the Browser, the clip’s markers are exported.
More About Compression Markers
Compression markers identify areas of abrupt change in your sequence, such as a cut
from a black room to a bright grassy plain. Compression markers are automatically
inserted by Final Cut Pro at all edit points. You can also place compression markers
where you want; these are forced compression markers. When a movie or sequence is
exported with compression markers, the exported QuickTime movie has an extra text
track, in addition to the video, audio, and timecode tracks.
Some video compression applications, including Compressor, are capable of using
information in the compression track of your movie to optimize the placement of
I-frames during the process of MPEG-2 compression to achieve maximum playback
quality. By correctly identifying cuts, transitions, and gaps in your sequence, you can
avoid compression artifacts in these areas of your final movie on DVD. See “
About the
MPEG Format ” on page 218 for more information about I-frames.
