Eliminate embedded subitle MKV file - edit after with Any Video Converter?

[Ze Tomes]

My purpose is simple:

I want to separate the subtitles embedded on a matroska file - generating only 2 files. The video, the subtitles.
So that I can edit a movie (subtitles / movie) on Any Video converter.

The problem starts with:

If I open a matroska embedded subtitle file on Any Video Converter, the result of the edition would be a movie with fusioned subtitles, what I don't want. I tried every possibility on Any Video converter I could remember but the problem keeps the same.
Even if I extract the subtitles, label the file with the same name of the video file, turn off the subtitles on Any Video Converter, they will continue to be fusioned on the resulting edition.

After that I used MKVExtractGui extracting everything except the subtitles, used mkvmergegui merging these resulting files, hoping I had the solution for the problem. I think I steped correctly the guides using both programs, but as I'm very green on both programs of MKV tool mix there may be many errors.

Then I tried to edit the last file (mkv tool mix result) on Any Video Converter, and it wasn't recognizable... or it just processed 20 minutes of the movie for example.

I would like very much an help on this as I don't know if I'm making any mistake on the process or if Any Video Converter doesn't recognize these kind of MKV tool mix resulting files.

Thanks very much for your attention.

Use mkvmergegui. Open mkv. Delete subtitle track. Save as new mkv. You can try disable the header compression also and it may work better to open in other tools.

After I extracted the the audio and the video files on mkvextractgui, merging them on mkvmergegui, the result wasn't synchronized...

[Ze Tomes]

how can I know the right values so I can syncronyze both audio and video, on mkvmerguegui > format specific options > delay?

Don't extract it and it will stay in sync.

Don't use mkvextract, use mkvtoolnix ONLY , uncheckmark the subtitle streams, press start muxing

I've tried the mkvmergegui executed by mmg.exe hypothesis as you advised... but the same problem of delay between audio and video persists. There's any configuration I should avoid,or follow?
The mkvtoolmix you're refering is executed by mmg.exe right?

Thank you for your support

I think it's resolved, I simply didn't configure anything, neither compression rates nor aspect video or VFR, anything, and just unchecked the subtitle option. It resulted perfectly.

Thank you very much for helping me resolving this nasty one. Hope somehow this will be usefull for others

Cheers
