How to save avi embedded subtitles into a text file?

[markiz]

I have a avi file that was re-encoded with subtitles (There was an avi-video which was encoded again with subtitles)
i want to extract those subtitles and convert them into standard *.srt subtitle.

Is it possible?

You need an OCR software to be able to convert the burned in / hard subtitles from the avi. You can try AVISubDetector (and I think subrip also supports avi).
