Changing FPS of m2ts file
Hi! Is there a way to change FPS of m2ts and then save it as m2ts using Avisynth? Because I'm struggling with strange FPS like 23.974 or 23.975. FFVideoSource shows me these strange FPSs, DirectShowSource shows standard 23.976, but I think that FFVideoSource is more reliable. I know that there are functions like AssumeFPS or ChangeFPS but I don't know how can I use it when I want to save it again to m2ts.

It's unlikely it is not 23.976. Can you post a link to a small unprocessed source sample so we can see from the stream syntax itself what is going on versus trusting some tool.
Also, is the m2ts from a bluray? If not where does it come from? Last edited by Guest; 25th November 2013 at 17:38. |

m2ts comes from a blu-ray and here is the sample:

But what if they messed up this videos? When I created subs for it in 23.976 and mux it with BD it was obviously out of sync. Could it be something related to variable framerate?

Nope. By default FFVideoSource put the fps checking timestamps of first and last videoframes, and most the times you finish with unnacurate fps values like 23.975.
After FFVideoSource I always use AssumeFps(24000,1001), when I know the source is 23.976 from BluRay.

Same suggestion from tebasuna51 about assumefps also applies to directshowsource due to rounding errors.
