OGM to MKV

[GreenGremlim]

Hello, I have some anime on .ogm with multi audio tracks and selectable subtitles, anyway to encode/convert to mkv keeping all audios and subs? I also have other anime on MP4 with ssa subtitles that want to convert to MKV with selectabe, not hardcoded, subtitles. Thanks in advance.

if you are looking for a tool that can do the mentioned, use mmg (mkvmerge gui) or mkvmerge directly.
Simply drag&drop all content that should be in the output mkv into mkvmerge GUI and hit 'Start muxing'
