how to change framerate in x264/mkv file?

[Rodion]

I have matroska file with a video stream which framerate is 25, this is the only stream in the file.
I want to change fps in the file to 30.

Question is: can I do it in some way?
It there an utility to help me?

Sure I do not want to reencode the file

Remux it using a timecodes file like this:
# timecode format v1
assume 30.0

Docs here (http://www.bunkus.org/videotools/mkvtoolnix/doc/mkvmerge.html) for the command line version, or MkVMerge GUI has a field for the timecodes file in the "general track options" panel.
