900731 Data Handling for Eye-in-the-Sea on MARS : AVED Data Model

Important

AVED reports indexes movies by Framenumber. Need to convert this to timecode. What is the framerate of the AVED movies?

D.Cline. When AVED recognizes a time code track in a QuickTime container, it associate events to this timecode, otherwise it uses the frame number. It looks like the example here simply did not have a timecode track in it.

The framerate of the movie will be encoded in the SourceMetadata->frameRate field.
