mkvmerge, timecodes and fps

[SledgeHammer_999]

I have a video that is vfr(variable framerate). I extracted the timecode file with ffmpegsource and I reencoded it(with x264).

Now I want to make a new mkv file with mkvmerge. I specify the timecode file for the video track, but mkvmerge complains about the fps. I thought that it can "produce" the framerate from the timecode file. If not, can you tell how to determine what value I should put there?

ps. I use the gui mkvmerge.

It's a known error in the GUI. It will always complain if you don't set the fps, even if you specify a timecode file. Just ignore the error message.
