vspreview: Incorrect Frame Rate

[jay123210599]

No matter which source I use, I always get the wrong frame rate from one of my videos. How do I fix it?

Im trying to get the original frame rate, but I either keep getting the other frame rate instead or simply an incorrect one.

You may try BestSource()

BestSource did not work, either

Then it might be borked by the last encoder, or real VFR.
I have no access to your source, but I would inspect all frames, their motion, and maybe the damage can be undone.
In the worst case by exporting them all, dropping the repeats, count the uniques and Assumefps them across the new timeline.

Here's my video.

It's TRUE VFR

It's 24p and 30p mix
I assume that only the credits part of the video is 30p so maybe you can do some black magic to it but that's complex just extract and mux the timestamps and call it a day if you are doing some VapourSynth but if not just use FFmpeg to handle the VFR with -fps_mode

I don't want to encode it, I just to play it at its original frame rate (23.976 (24000/1001) FPS) in vspreview.

Use AssumeFPS
