Changing Video Track Settings
The settings of the Video track can be adjusted in Logic Express > Preferences > Video.
 Cache Resolution pop-up menu: Choose the resolution of the thumbnails held in the
temporary internal memory (cache). Higher resolutions display more detail, but take
up more space in the cache.
 Maximum Cache Size slider: Sets the amount of memory reserved for the thumbnail
cache. 40 MB is recommended for medium resolution. Use a higher value for higher
resolutions. The cache memory will only be used when actual movie data is
displayed.
Working With Scene Markers
Scene markers are SMPTE-locked markers: They remain at the same absolute time
position, regardless of any tempo changes, and they are automatically deleted if the
current movie is removed from the project. Scene markers are identified by a movie
frame symbol.
