I shot at 23.976 but the footage is in slow mo?!

I did a two camera shoot, one was a Canon C300 the other was my Blackmagic URSA Mini Pro.

Both were set to 23.976 fps. Both were recording to ProRes HQ

I get the footage back and the Ursa Mini Pro footage is almost twice as long and in slow motion yet the metadata clearly says 23.976!

I've even tried checking it between Davinci and Premiere just to make sure it isn't software related.

Has anyone had this problem? Any ideas? This sucks because it's a band performance and has to sync perfectly.

Doing research is it possible the sensor frame rate was different? I'm so confused rn and have no idea how to fix this

Also the audio on the footage is normal. Syncs up the all the other audio which is good, but at the end the audio goes silent and then the video continues to play. Leading me to believe yes it's a different frame rate even though it says 23.976fps

Anyone know a quick way to batch fix this? I guess I'd have to find out what the frame rate it was recorded was at but the camera is not in my hands...

Actual shooting frame rate and 'project frame rate' or 'clip frame rate' are two different things.

Various camera manufactures label the settings slightly differently, but in essence:

Shooting 60fps to a 60fps project frame rate gives you normal speed.
Shooting 60 fps to a 24fps project frame rate takes your 60fps and distributes them 24 frames per second, meaning that one second of your 60fps footage will take 60/24 = 2.5 seconds to play.

To fix this, just conform your 'slowmo' clips to whatever frame rate they were actually shot at, and you'll get normal speed. Then you can drop them into any modern NLE and it should handle them just fine.

In Resolve you can conform your clips to another speed by right clicking on one or several highlighted clips in the media page and by choosing 'clip attributes(?)', or something similar.

Sounds very much like you shot 59.94 fps footage in a 23.98 project. You are lucky that this should not be a problem in editing. I would take it as a warning that you should study the camera manual some more, and experiment with settings you have not used.

Thanks guys, yeah I guess I didn't realize there was two places to affect the frame rate.

And yes, I just figured a workaround and the clips were recorded at 30fps, everything works, thanks!

Had the exact same problem but having Premier interpret the footage as any other "standard" frame rate (24, 25, 29.97, 30, 50, 59.94) did not help. The metadata said 23.976 and interpreting the footage as 30 it still did not match the original audio. I started manually entering in the frame rates until one worked.

32.97 fps was the winner. I have no idea why. I dont think thats an option on the Black Magic but the footage plays perfect now. Has anyone ever heard of this? Ive scratched a hole in my head trying to understand.

EDIT: Just learned about the "Off Speed Frame Rate" option on the Ursa. I think the camera guy had it at a random number by accident. Very cool.

32.97 fps is 33/1.001. It is common to shoot at 33 fps to slow things down ever so slightly such as additional shots to be inserted in a larger clip to highlight some action where the short insert doesn’t rely on audio as that’s taken from the original larger clip. Pick Up shot.

Hello all, I don't think this problem has been resolved.
I experienced it recently, we shot at 25fps - ProresHQ, but when we tried playing back on a 25fps timeline in Premiere (and Resolve), all footage plays back slow (no dropped frames but slow). Kindly note, we shot on 2 Blackmagic pocket 6k and both have the same issue.
All metadata says 25fps...

Could someone from BM kindly assist...?

Hi, I know this is an older post...but how did you end up resolving this issue in Davinci Resolve?
I shot a film for a client, and all looked fine when I originally reviewed the footage on site, but now everything is in slo mo (even my back ups...so I guess it didn't look fine originally) but the meta data in DaVinci says my footage is 24 fps.
I am not really sure what to do here as I am a new to this. Any help would be appreciated.
