Tool to configure delay in MKV file

[bananacreamandpeca]

I made this MKV file with AVC-video and mp3

The sync is off.
Are there tools that let me set the delay for the video/audio in the MKV?

you can use avimuxgui

load the video, press generate data source..., click on the auiostream, enter delay and hit start ...

If you mux with MKVmerge, it can also set delay for audio.
Just load the .mkv, select the audio stream and set the custom delay you want, export to .mkv

Cheers.

Thanks.

Only the MKV I have already has audio and video muxed together. And the audio has a delay (video progresses slightky faster than the audio)
I thought i saw a screenshot for thisw MKV tool where you could re-adjust the delay for the audio.
But it couldve been just my imagination

MKVmerge is that kind of tool. Is basically todays must-have tool for MKV muxing, for features and easy of use.
It doesn´t matter if the file is already muxed, load it and you´ll see the streams that it carries. Select the audio one and adjust the delay.
Cheers.
