About the Movie track
The global Movie track displays the opened QuickTime movie as thumbnails. If the Movie track is
not visible, see
Show and hide global tracks .
The number of frames displayed on the Movie track depends on both the track height and
the zoom level of the window. All frames are aligned left, with only the very last frame aligned
to the right. This guarantees that you can always see at least the first and last frames of video,
independent of the current zoom level. Given the left alignment of all frames (except the last),
the left margin of a frame is always displayed at the exact position of that particular frame.
Movie track settings can be adjusted in the Movie preferences window. See Movie preferences .
Use movie scene markers
Scene markers are SMPTE-locked markers: they remain at the same absolute time position,
regardless of tempo changes, and are automatically deleted if the current movie is removed from
the project. Scene markers are identified by a filmstrip icon.
You can use the Create Movie Scene Markers function to search the movie for significant content
changes (scene cuts), and automatically generate scene markers for each of them.
The Create Movie Scene Markers function uses a fixed threshold value, which works well for most
types of movies: cartoons, real life, CGI, and so on.
