extracting subs from divx/xvid

[Kracov]

I have this old video in divx format. I tried to open it with SubtitleEdit and began the process of OCR conversion. There was an error message and the program shut down. Is there a more reliable way of extracting or viewing the subtitles? Even if I can just view it, I could copy it and save it in notepad as a srt file.

You can use clever FFmpeg-GUI.
Load your avi, click extract streams, select the subtitle stream only and click extract.
Your subtitle will be extracted into an avi container.
This avi can be further converted by subtitleedit.

BTW.
Divx subtitles (xsub) are bitmap subtitles. You have to OCR them to save them as srt.

It was unable to extract the subtitles since it is zero bytes. Any other ideas?

Can you see the subtitle as separate stream (like in the pic)?
If not, your subtitles could be EIA 608 closed captions.
In this case you could try the EIA 608 extraction in clever FFmpeg-GUI.

yes its a separate stream- it said for all streams including audio and video: zero byte file was generated. empty source or the file was deleted.

Could you upload this avi here, so we can take a look?

Load your divx file, click multiplex, set avi as container, click multiplex.
If finished, load the new avi and extract the streams.

[Kracov]

okay, I was able to multiplex it into an avi. however, opening that avi in SubtitleEdit resulted in the same error message

Here you go.

Thank you. Out of curiousity what did you do exactly? The first thing the OCR asked me to type in was the left parenthesis character and got that error.

You must change the OCR method, from binary image compare to tesseract.
Adjust the dictionary too.

i get a "download failed" when trying to use Tesseract 4.0 or use the English dictionary.

Disinstall subtitleedit and download the newest portable version.
