Changing FPS in MKVs

[infiniter]

I used to synchronize audio and video of a MKV video stream (HD rips) with 24fps and of a AC3 audio stream (from PAL DVD) with 25fps by using MKVMerge and re-merging the english movie with the DVD ripped german AC3 track. I just set the FPS of the movie to 25 and delayed the audio so it was synchron.

Now I have the same situation. It's also a MKV with a MPEG4/ISO/AVC stream, but in MKVMerge I can't set the FPS.

Any idea how to circumvent this? Is there any other merge tool that does this job without recoding anything?

TIA!

Where did you obtain said MKV?

Just use a timecode file for the video stream.

I doubt that a timecode file, apart from that I don't know what a time code file is and how it is created, will convince the player/codec to play my MKV with 25fps instead of 24.

Yes. People usually try to give you advice that most definitely is not going to work. This is why you came here for advice.

Create a text file like this

# timecode format v1
assume 25

You can use this when muxing in the general track options tab under timecodes of MKVMerge GUI. Of course you can replace 25 with any fps you want.
