Thanks for all the replies.
We are starting with a trailer of the film, so a few days ago I received a QuickTime MJPEG 720p @ 23.976 fps. This was imported into a Pro Tools session also set to 23.976 fps, and when the OMF was imported into Pro Tools, everything sync up, so I presume the OMF is also 23.976?
Now I have some more doubts
and am still a bit confused about what is actually happening here.
When I record my master in Pro Tools ready to pass on pic. editorial, the new audio files created show up in the Workspace as 48kHz files. Doesn't 48kHz equate to 24 fps, and shouldn't my new files be 47,952 files as my session is running at 23.976 fps?
My principal concern is how my master audio is going to sync up / playback in FCP, as the film is being kept at 23.976 fps right up until deliverables / printmaster.
What do I need to do to output a file for them that will sync up and will not be pulled up/down or messed about with in any way by FCP?
Thanks
