Legend
A - All media and cache resolutions can be played back, processed, and purged.
B - Video caches can only be generated in quarter resolution. Full/half resolution caches that already exist can't be
purged or manipulated from the timeline. To purge these caches, you must use the purge manager or media
manager. Even if full/half caches exist, Avid|DS will display the "Needs Processing" message in the viewer.
Backward Compatibility
 You can use NTSC and PAL sequences created in Avid|DS 4.0. We highly recommend that you use the
archive/restore tool to bring sequences from earlier versions into version 4.02. Otherwise, if you open a 4.0
project in version 4.02, incorrect behavior may occur.
 Once you save or archive a project in version 4.02, it cannot be opened using earlier versions of Avid|DS. If you
need to access the project again in version 4.0, make sure you archive the project in version 4.0 before using
projects in version 4.02.
