Changing fps of a lot of files with mkvpropedit

[Famille_CB]

Hello,

I'm trying to force the number of Frame Per Second to 25 for lot of files.
I tried JMkvpropedit but there is noway.
Now I try to write a batch file withe Batchenc.exe : http://members.home.nl/w.speek/batchenc.htm

I have sommething like this:
"tools\mkvpropedit.exe" <infile> --edit track:v1 --set default-duration=0:25p
but it doesn't work.

Is it possible to change fps with Mkvpropedit.exe and if yes, with what kind of command line?

I think that Mkvpropedit use same commande than mkvmerge that's why I use the command :--default-duration TID:x

What is "TID"?

Can you help me please?

Thank you.

Players use the timecodes for determining playback fps (Matroska inherently utilizes VFR), not the default duration element. You have to use mkvmerge.

Ok,

Then you think I have to re-mux all my files!
No solution with Mkvpropedit?

I'm French and I don't understand all the documentation.

Any way, if the solution is thu re-mux, I will re-mux.

Thank you.
