Framerate conversion (NOT telecide)

[exobyte]

I did some video editiing a while ago, now I need the footage again (lost the original). I slowed it down, and there are about 3 framerates through a 30 sec clip. Is there a way to automatically remove these frames? The pattern isn't x,x,x,x,duplicate, so most filters get confusted. It is almost always in motion, so it should be possible.

Post a link to a sample clip. There's no way for us to guess how you generated the video or what the original source looked like.

One approach is FDecimate(). If the original was X fps and you added duplicate frames to bring it to Y fps, then you can use FDecimate(X).
