My sequence in Premiere (7.2) is 1080p @ 23.98fps. When I send it to Audition through the Edit menu, it renders a video file at 29.97. Audition recognizes that the video is 29.97, and it also shows the timeline as 23.976. The duration is the same, and so far I haven't noticed any problems, but why does it do this?
These two screenshots were taken simultaneously in Audition.
I see the same here. My guess is it doesn't really matter much.
