Improved Closed Caption handling

First, I would like to compliment the idea of implementing libass to make your Closed Caption subtitles positional, making them truer to their roots. I am proposing possible adjustments to your CC support, taking advantage of libass. These can be made into options, selectable at the user's discretio...

Re: CUDA support

As far as I know, x264 won't support CUDA or anything similar. From what I've read in x264 forums, the problem is that the techniques used in encoding H.264 properly and optimally don't fit well within the limited environment of a GPU. For example, since MPEG encoding is interframe rather than intra...

Re: Suggestions For CC Handling

I do not wish to be a bother, but perhaps I am not so clear on what the thinking is around here. Seeing as how QuickTime and video iPods support Closed Captions as Closed Captions (and feature options for such), is there anything preventing the encoding of Closed Captions as Closed Captions ? I am ...

Re: [Updated: SUCCESS!] Non-Handbrake solution for Subs/Captions

Try mp4dump from mpeg4ip. Rodney Well, I got something out of it. I managed to perform a dump on my test MOVs that contains nothing but CC information, though I don't think I have the whole story. If you wish, I could pass along the information to see if anyone can wrap their heads around how c608 ...

Re: REQ: Custom chapters

At this point, you are best off approaching #x264 on irc or asking on doom9. This has become an x264 question and not a handbrake question. The old patch to x264 has been provided. Use of the x264 executable is a x264 issue. The qpfile has been simplified and no longer requires a line for every fra...

Re: REQ: Custom chapters

Re: REQ: Custom chapters

How on earth would x264 know what a "chapter point" even is in order to put an I-frame into one? Rodney The same way Handbrake's modified x264 core does it--you tell it in advance. Once it knows the frame number of the chapter point, it can make sure that that particular frame is to be both an I-fr...

Re: REQ: Custom chapters

-qpfile. It's been there for quite some time. See --longhelp for (some) details. Rodney That? That's intended to manually fine-tune the frame types and quantizers for every single frame of the movie. From what I've read, you can't just specify a qpfile that contains a few key frames you want in a c...

Re: REQ: Custom chapters

x264 (the CLI encoder itself, not the one built into HB) doesn't allow for custom I-frame insertion last time I looked. Actually, I think it does, but you have to feed it a text file indicating which frames should be forced. Rodney Interesting. That's been a feature request and one reason I wanted ...

Re: REQ: Custom chapters

What about Windows users like me? For MKV the standard mkvtoolnix suite includes a chapter editor (in mkvmerge), http://www.bunkus.org/videotools/mkvtoolnix/ For MP4 content it's a bit more complicated, but apparently YAMB will handle it if you have a chapter file in correct (OGG) format, this form...

REQ: Custom chapters

I am making this request because I am running into two scenarios where automatic chaptering fails: 1. The source material is something like an AVI file for which chapter information does not exist. 2. The source DVD material is a cheap or otherwise lousy DVD for which the chapter layout is very poor...

Re: [Updated: SUCCESS!] Non-Handbrake solution for Subs/Captions

UPDATE: I'll be frank. This whole exercise has been like pulling teeth, and it seems even at this point I'm not getting anything near a proper clcp/c608 track (keep getting things like "wide" atoms). Perhaps a better approach would be to bypass QuickTime altogether and create a MOV file directly. Ho...

Re: Suggestions For CC Handling

Hang on. Video (5G and up?) iPods you say? What happens if you play an m4v with CCs on a video iPod with CCs turned on? Does it (the iPod) shows them (the captions)? If so, then one can see how this option may be considered superior in some respects to soft subs since soft subs simply aren't suppor...

Re: [Updated: SUCCESS!] Non-Handbrake solution for Subs/Captions

Quite interested in this myself, since Subler doesn't seem to be available (even in CLI form) for any platform other than the Mac. Hint. *laughs* Rodney Well, as they say, nothing to it but to do it.

Re: [Updated: SUCCESS!] Non-Handbrake solution for Subs/Captions

iTunes CCs are just Quicktime CCs in an MPEG-4 container. They have documentation on Quicktime CCs for programmers. iTunes Subtitles are MPEG-4 Timed Text tracks. Heck, Quicktime now recognizes and displays proper timed text tracks that are embedded into an .mp4 using mp4box. The catch is that I ha...
