How to pass from .Sub + change size and font to .Sup ?

[kalemvar1]

Hello

Is that possible to convert .Sub file, change the size and font to finally convert it to .sup file ?

I've read few posts here, and as far as I understand I need to .Sub to txt mode, change to size/font and back to .Sub, but I would love to avoid that. Specially that if I change it to .txt lost all subtitle position (specially the one on the top of the screen)

Thanks

What kind of SUP file? DVD or Blu-Ray?

To merge with .mkv files. Sorry I haven’t specified

Open .idx/.sub (or the file containing said subtitle) in SubtitleEdit, go through the OCR process, then "File"->"Export"->Blu-ray sup". (I would also export as .srt and if you want a font as .ass. Both can be put into mkv without really requiring any space and it's always nicer to work with text subtitles.)
