Choppy video 50fps to 25fps

Hi dear users,

I'm shooting in 50 fps on my BMPCC to make some slow motions in further, but after export in 25 fps I have choppy video.

Is there any options to avoid it at set or at post production?

Thanks

Define "choppy".

Is the timeline not playing at 25FPS?

Or is it simply that movement in the video appears choppy -- in which case this is an artifact of shutter-speed.

A 180 degree shutter at 25 FPS is 1/50th but footage shot at 50FPS with a 180 degree shutter will be 1/100th which produces less motion blur. As a result, high FPS footage placed on a lower FPS framerate will always apper more jerky when there's rapid movement. You can reduce this effect somewhat by using the motion blur control on the color page but the results will *never* be as good as using source material with the correct framerate and shutter speed in the first place.

You can try to use a 360 degree shutter when recording in 50p.
Are you sure that no frame interpolation is activated in the project? It may kick in even if not needed.
Is your video still choppy after export?

Try the following:
Mark the video clip - scroll all the way down in the INSPECTOR and select "OPTICAL FLOW" under RETIME AND SCALING in the RETIME PROCESS.

Sorry, but that's not needed going from 50 to 25 fps.

Are you shooting in HFR mode?
