Chapter 8 Global Tracks 347
There are no editing options in the Video track. It does, however, offer the Detect Cuts
(button in the track column) function, which searches for all scene cuts in the movie.
The Video track also offers the option to create Movie markers, which are displayed in
the Marker track or the Bar Ruler. In addition, the first frame found after each detected
cut will be displayed as a thumbnail, and the cut positions will appear in the Beat
Mapping track as events, allowing bar position mapping (see “Beat Mapping to Movie
Cut Positions” on page 340).
Movie markers have a special status compared to regular Markers: They are SMPTE-
locked (they remain at the same absolute time position, regardless of any tempo
changes) and they are automatically (after a confirmation dialog) deleted if the current
movie is removed from the song. Movie markers are identified by a movie frame
symbol.
Note: Some settings for the thumbnail display can be found in Logic’s Video
Preferences (see “Video Settings” on page 639).
