I have an mkv file here with idx/sub subtitle. I want to convert it to sup format.
I searched the net and found out about easysup but when I opened the sub file in the app, it's nothing like the easysup page on doom9 (http://forum.doom9.org/showthread.php?t=149160). All I get is a blank screen. and nothing on the "log" window. It's a different story when I open an srt file.
Plus when I try to open a subtitle, it clearly says "text-based" subtitle files in the dialog box. Well, from what I understand, idx/sub are not text based but actual images thus needing OCR to convert to text.
I also found subtosup but that's from like 2002 and no further development has been done.
Thanks for the help :)
