I did a couple of tests to look at mv2s made by Compressor and BitVice using MediaInfo. (23.98 is shorthand for 23.976.)
Compressor
23.98 chosen as the frame rate in the Video Format tab of the Encoder – mv2 shows as 29.97 with pulldown in MediaInfo
29.97 chosen as frame rate shows as 29.97 with no pulldown.
BitVice
23.98 mv2 shows as 23.98 with no pulldown. DVDSP rejects this mv2 as a non-standard format which it is. DVD players will only play files they recognize as 29.97.
29.97 mv2 shows as 23.98 with pulldown which is why it’s accepted in DVDSP
It’s my guess (I don’t know this for certain) that for a frame rate of 23.98, Compressor is using a similar process to BV, just reporting differently. When BV makes a 23.98 mv2, it really is 23.98, not 23.98 with pulldown flags set.
I hope this makes sense.
