Chances are whatever is reading the file is doing it incorrectly.
Thanks Jim. I exported at 24 fps, it transcoded and output ProRes 422 file correctly. But 23.976 fps export does not work, still outputs mov file at 23.7 fps. I met the deadline today by submitting 24 fps mov file. However, I need to sort out 23.7 fps issue soon, it is weired. Any suggestions!
23.7 according to what software - how are you determining the output frame rate?
Quicktime player inspector [opt + i ] where file property information is shown indicates 23.70 fps. When we played the exported QT file on theater Christie Projector, the video and audio were completely out of sync, and video was not playing smoothly. (due to incorrect fps).
When I exported the same sequence (as is, no changes) at 24 fps, Quicktime player inspector indicated 24 fps, and it played perfectly on Christie Projector (audio and video in sync running smoothly).
In both cases same sequence was exported as ProRes 422.
still outputs mov file at 23.7 fps.
Chances are it isn't, it's just the software reading the frame rate incorrectly.
If the software reading frame rate incorrectly, then why mov file didn't play back properly on the theater projector system? 24 fps does play properly on the same system. Video edited on PremierePro submitted by others at 23.976 fps does play properly.
I just did export of short (~2GB) segment of the same sequence I was working on:
one export with 23.976 fps, the output mov reads 22.79 fps (different reading than the prior 23.7 fps)
the other with 24 fps, output reads 24 fps.
I checked my previous export (a month ago) ProRes 23.976 fps, the output mov reads 23.98 fps.
I don't think software is reading fps incorrectly.
