Thanks Mark,
as Nicolas already pointed out, I was wrong about the mkv format. I see you are using it for just a
subtitle stream too in the first step.
Though my problem is already solved with that, what you wrote looks very interesting. You are able
to convert image subtitles to text?
Indeed. It has removed my dependency on opensubtitles.org -- really messed up, low quality, soon to
put up a paywall -- for HDMV PGS subtitles.
I really should check out SubtitleEdit and that MKV toolkit too.
SubtitleEdit can grab subtitles directly from M2TS files but it makes mistakes whereas I've found
that taking the time to make a sub-only MKS, and then have mkvextract make IDX & SUB files to submit
to SubtitleEdit is reliable.

Hi, Below is a Windows CMD I use. It employs ffmpeg, mkvextract, and
SubtitleEdit.
The MKV made has only the subtitles -- no video required.
If SubtitleEdit has been properly trained, the results are excellent.
