Shot on Bolex @ 32fps instead of 24 - How do I convert to 24fps without slow motion/ fast shutter look?

Shot a music video where I need to sync sound @ 32fps instead of 24, when I got the scans back everything is slightly in slow motion, anyone have any ideas as to how I can get the footage to play at 24fps without slow motion and the jittery fast shutter speed look?

    since the film was cranked at that speed, you can't simply change the speed without it looking jerky since any motion that would have happened at 24fps is going to be split into different movement chunks. You will need to interpolate with optical flow.

      probably need more info. Are you talking about an old bolex that shot 16mm plastic film stock at 32 fps MOS ? And you want to convert the telcine to 24 fps ? And you want to sync it to some sound file ??

      No clue what you looked at the 'scans' you got in... was that PPro in a 24fps timeline ??

      Yes shot 16mm film on a Bolex @ 32fps - the film was scanned @ 24fps so now it's in slow motion. I've interpreted it to 32fps and placed it in a 24fps timeline but it still has a sort of sped up or fast shutter look- I want to know if its possible to change that

      You're probably just seeing lack of motion blur since the footage has been captured at a higher frame rate which inherently has less motion blur. You can add motion blur back in with Pixel Motion Blur in After Effects or RSMB​.

      Out of curiosity, why was it shot at 32fps? Such an odd frame rate.
