  1. Hi,

    I have few MP4 files with embed ClosedCaptions.
    I usually use CCextractor to extract the subtitles to SRT files, but I'd like to extract the CC with text positions. I tried to extract as SSA, but it won't work.

    Is there any other program that can do it?

  2. I have been working on a program (a web page for now) that'll do exactly what you're thinking of. It requires a Closed Caption Disassembly file as input, and spits out a positioned SSA, formatted to look like closed captions.

    I''ll put up some sort of tutorial on how to generate a disassembly file (CCExtractor to make a RAW file > raw2scc to make a scc file > ccasdi to make a disassembly file), but until then here's a script (bundled with a bunch of programs I'm really not supposed to be bundling and distributing) that'll do it automatically.

    This assumes the source-file contains legit closed captions (cea-608) and not some other type of subtitles.


    pre-pre-alpha

    Edit: a lot of functions aren't implemented yet, like roll-up captions (used for live or near-live events) and paint-on captions (used when there's no time to build up a buffer, like immediately after a commercial break; NBC uses these on all their shows)

  3. Thanks, great program so far.
    I successfully created an ssa file, but all subtitles duration are less than 1 second...

    If you paste in some (or all) of your disassembly file, I can tell you what's wrong.
