Mpeg2 Settings

Previzion has the ability to decode multiple Mpeg2 videos at the same time for use as textures on elements inside scenes.  However due to some quirks in mpeg2′s history  as a broadcast format not a file format Previzion can have a hard time accurately determining the length of Mpeg2 clips if they don’t have audio tracks embedded in them. This is very important for scenes with multiple clips that must loop and play back in sync. ”Blu-Ray” encoding settings encode separate audio and video files which do not work well for Previzion to accurately time.

The easiest solution is to encode Mpeg2 files with audio tracks embedded in them; the audio tracks can be completely silent, but they must be there for Previzion to accurately display clip length..
