Hi, I have a mkv file that was made from a DVD. That file has several audio tracks containing subtitle information. When I open the file in VLC, the subtitle tracks show as Codec: DVD Subtitles (spu) My goal with MCEBuddy is to convert the video file into MP4 (currently using MP4 Normal but also t…

It looks like you’re having trouble getting MCEBuddy to extract VobSub subtitles from your MKV file and convert them to an SRT format, even with the OCR add-on installed. The log shows that MKVExtract is able to create an IDX file, but then MCEBuddy reports a FileNotFoundException for a .tmp file an…

Try the latest 2.7.1 beta, the whole subtitle extracting has been revamped and full OCR detection and extraction capabilities have been added to it (you’re on 2.6.6 which doesn’t support all types of OCR).

Hi Goose, Thanks! With the latest 2.7.1 beta, I am getting further. I enabled the “Extract burned in subtitles” setting. Note I still have Audio Language set to Default. I do now get an srt file (and an idx file in the destinaton directory), but it is unreadable. See attached. Twilight (2008).mkv…

Hmm, I don’t see any obvious errors in the logs but I see the file has some issues. Will need to replicate it to see what’s going on. Can you upload the entire original file to the server so we can analyze it to see what’s going on.

Hi Goose, Thanks! I just uploaded it to the jspang folder on the FTP site. Let me know if you can reproduce the issue. Really appreciate you taking a look. I hope to get some more time tonight to try another file for a different movie that has image-based subtitles to make sure this isn’t just a f…

Hi, Just got around to installing the latest beta. I redownloaded the OCR files and ran the converstion again. Now, instead of getting a scrambled srt file, I get a few .idx and .sub files, and no .srt files. I can process these via a program like Subtitle Edit, but not sure if this is intended? T…

That’s the output expected. If it’s has a sub and idx file then it’s kept as is. Those are image based subtitles since most players can play back sub / idx subtitles. If you have a hard burnt in subtitles then MCEBuddy will perform an OCR to convert those into SRT files or for some reason if it’s u…

Hi, Perfect. For some reason I was under the impression that it was supposed to be srt. Apologies for the confusion. This is all solved then. I’ll continue to test the beta as I have a bunch of other media with image based subtitles and if any issues come up, I’ll report them seperately.
