ProRes4444 export changing frame rate to 21.98
Hello. I'm really stumped on this one. I am exporting a 90mins sequence for colour (all as one video with an accompanying EDL). The post house has requested the file as ProRes4444.
When I export the sequence, even when the output summary indicates that the media will be output as 23.976, the final video ends up being delivered in 21.98fps.
I've selected the following in my export settings:
Format: QuickTime
Present: ProRes4444
Video Code: Apple ProRes 4444
CHECK Render at Maximum Depth
CHECK Optimize Stills
CHECK Maximum Render Quality
The thing is, when I export only a small section of the timeline as a test - the frame rate is totally fine and the video is exported in 23.976. It's only when I export the large file that this 21.98fps issue is occuring. If anyone can help that would be so appreciated.
