Video goes to fast. MKV extract

[MiniMinimal]

Hello!

I got a MKV file that i have extracted with MKVextract
(i have to convert the AAC sound)

but video is to short, it is like it have been timestretched, or something??
so everything goes out of sync

What kind of video? AVC/H264/X264? it can be VFR(variable frame rate) and you will get sync problems then, see https://forum.videohelp.com/viewtopic.php?t=312647&highlight=vfr

Identify the video in a MKV with mediainfo or gspot. Or maybe mkvextract gui shows the video codec.

I looked at the thread, and it is the same problem as he got..
but when i'm try to load the mkv file in vdub and do as he díd, it says that it don't support the subformat.

Oki.. i did find the solution!

I made a new mkv file with mkvtoolnix, without subs and sound...

It was VFR!

THANX ALOT FOR THE HELP!
