EXAMPLES:
-
<essenceTrackFrameRate unitsOfMeasure="fps" annotation="interlaced">29.97</essenceTrackFrameRate>
-
<essenceTrackFrameRate unitsOfMeasure="ips">3 3/4</essenceTrackFrameRate>
-
<essenceTrackFrameRate unitsOfMeasure="fps" annotation="progressive">50</essenceTrackFrameRate>
VOCABULARIES:
- PBCore essenceTrackFrameRate
- Use the annotation attribute to indicate Progressive or Interlaced formats.
If the element is defined as “frames per second,” it does not need unitsOfMeasure, and the suggested PBCore list seems wrong, as one would not need 3 3/4. There seems to be overlap with essenceTrackPlaybackSpeed.
