Does anyone know how to extract subtitles from a H.264 .ts?

[ALUOp]

I have a .ts (H.264) recorded from OTA HD program.
When I play back the recorded files, I can turn on and off the subtitle using the recording software.
I want to re-encode the file using a lower bitrate and put the subtitle back to the final MKV.
The only working program that I can find is ProjectX, but even though I selected .srt as the output format it can only output .sup & .ifo.

I also tried ccextractor, but it seems like it doesn't work on H.264 TS? It said "incomplete PES in buffer" and zero frames (see output below).

Does anyone know of any tools that can output .srt from a .ts?
The characters/fonts (Chinese not English) from the .sup (I later converted it to .sub) look different than the ones I see in the recording software, so I think the subtitle is text-based and thus should be able to be extracted.
Any ideas?
TIA :thanks:

How did you convert sup to sub?

You can try SubtitleCreator to convert sup to sub and open your sub with SubRip to create an srt file. I can't use SubtitleCreator because it crashes all the time.

If SubtitleCreator doesn't work for you, try this:

This is the way I use now. Download a new beta of ProjectX at the bottom of THIS PAGE (http://www.satnavigator.ru/page-id-52.html). Go to Subtitles settings and choose "additional export as VobSub (idx+sub)". Export the subs again and you will find new files, idx+sub.

Now get SubRip, I use version 1.3 because 1.5 doesn't work for me. Open your idx and now you should be able to "OCR" the subs to srt.
