    Hi, I am finishing a film in 23.98 fps but my colorist accidently mastered in 29.97 fps and it can't be undone, what is the best way to get it back to 23.98 fps? I work in Final Cut Pro X 10.4.4.
    When I view the files he sent me (in vlc for example), every fifth frame is a repeated still frame with no movement.
    I import the files into a 23.98 fps timeline in FCPX, but that fifth freezed frame is still there (and also when I export).
    How can I properly convert 29.97 fps into 23.98? I tried to convert it in Mpeg Streamclip going into 23.98 fps but it didn't work, it looks the same.
    Thank you for any help.

    Why can't it be undone? He can't re-render at 23.98?

    What I've understood it is not possible to just re-render (in Davinci Resolve), he would have to mount and grade everything from scratch again in a timeline of a different framerate. Sounds crazy, I know.

    That’s just wrong info AFAIK. I think your colourist has made a major mistake and is now asking you to pick up the pieces. I don’t know the exact or simplest way to do it in DVR, but have used the program enough to know there is definitely a way to do it.They should do the necessary research and work out how to make the change. Whatever re-transcoding you do on the export will cause a loss of quality. There are several great DVR forums around that should be able to give them the solution quickly and easily.

    Good luck!

    I render different clips in different framerates in 4K or in 1080 from the same timeline.

    I guess he imported clips with different framerates in his timeline. Resolve asks if the time-line frame rate has to be changed then or not. I think he clicked 'yes'.

    The main issue here would be the audio if it's locked (would be/may be slightly out-of-sync in the new timeline).

    Ask him to 'copy-and-paste' (or whatever you do in Resolve) into a 23.98p/24p timeline and export a new master and review it to see if/how noticeable it may be.

    That only takes a few seconds and you can at least take a look.

    ---

    At the end of the day, it's not the end-of-the-world if everything looks good, sounds good in the 29.97p/30p timeline, but it of course should be correct as it was intended to be.
