DivX 7 Adds Support For Blu-ray Rips (H.264/MKV)

mrspin writes "DivX looks set to continue to be the video format of choice for 'grey' content, with the company announcing that version 7 adds support for H.264 video and, more significantly, the Matroska (MKV) container. Anybody familiar with Blu-ray rips found on BitTorrent sites or other filesharing networks will instantly recognize the MKV file format in combination with the H.264 codec as a popular way to deliver High Definition video on a PC. And now that DivX is throwing its weight behind the Matroska container, MKV support should increasingly find its way on a range of non-PC devices, such as Blu-ray players, HD digital televisions and set-top boxes."

    While it wasn't mentioned in the article, it was mentioned in one of the many articles that it links to but DivX is facing Adobe in the marketshare for being the predominant technology streaming H.264. I believe this is Flash being used as a container to stream H.264 instead of the Matroska container.

    And now that DivX is throwing its weight behind the Matroska container, MKV support should increasingly find its way on a range of non-PC devices, such as Blu-ray players, HD digital televisions and set-top boxes.

    I don't know man, I think both DivX & Adobe have hidden costs even if both like you to view them as "open." I would put my money on Adobe coming through with better player/container support & marketing. On top of that, I don't know of any plans for DRM in Matroska.

    So while this is great news for the people who want to put their home videos out there with software that doesn't support DRM (is the average user really going to care though?), I think that the MPAA & porn industry are going to be the deciders here (as they usually are).

    My prediction: Flash 9 will become so pervasive that everyone will use that as a container instead of asking their users to download & install a DivX codec.

You can put H.264 into AVI but this involves putting the b-frames into the same packets at the i-frames and this causes the timecodes and seeking to get messed up.

      Because it's simply the best out there for it. It support just about everything you can mux into it. AVI just don't cut it any more. MP4 was close and it is a good container but it left one important thing out. In a bout of stupidity rivaling the bay of pigs and the bush election the audio codec of choice for dvd, ac3, was left out of the spec. That's right. The standard audio format can't be used in mp4.

      Now to be fair you can mux ac3 in a mp4 container using what is called user tracks or streams, or something like that. But that is not a official way to do it so it won't play on some mp4 devices.

      AVI seems to have alot more overhead than MKV. There is a utility to convert AVI files to MKV files and I noticed the resulting file was often a a megabyte or two smaller than the original AVI file. When you're targeting a storage medium with a relatively limited amount of space (e.g. DVDs, MP3 players, etc.) I suppose it could help fit a bit more content on there.

      I noticed occasionally I'd have audio sync problems on the converted files though so I stopped doing it since a few megabytes here and there doesn't mean much when you have a terabyte drive.

      I don't know why it's currently a favorite, but like ZFS, the goal for Matroska is for it to be the end-all be-all of container formats. They eventually want to be able to have DVD-like menu systems, for example. How sweet would it be to be able to rip your DVD (including menus and special features?)

      Matroska also supports an unlimited number of tracks. That's pretty neat, though I don't know if anyone's doing much with that.

      As I noted in another post, it even allows for variable frame-rate (VFR) encodings, meaning that the frame-rate can change in the middle of the video stream. This addresses a common problem with encoding DVD rips from sources with mixed content.

      Most modern television is filmed at 24fps (really 23.976). The film is then sometimes telecined to 30fps (really 29.97) to display on interlaced NTSC TVs. A goal for encoding is to reduce filesize--so if you can recover the 24fps video from the 30fps "source" (from a capture card or from a telecined DVD) then you can encode only 24fps instead of 30fps. In addition, you don't have interlacing in your output. The recovery process is called inverse telecine (IVTC.)

      The problem comes when producers draw on the video. Special effects may be created at a different frame rate than the filmed scenes. IVTC will be unable to recover if the animation is at 30fps. You'll get awful-looking animated shots. Alternatively, you can try deinterlacing instead of IVTC, but then you get awful-looking motion in the non-animated segments.

      Enter Matroska. Now you can IVTC when appropriate, deinterlace when appropriate, and simply keep the source frame-rate when appropriate. You get the best of all worlds, and all because you can store VFR video streams.

    It's not failed, not by a long shot. In fact, I'd say it's finally doing what mp4 never managed, that is killing AVI. Anime fansubbers would never use anything else these days - the only other container with reasonable softsub support is OGM, and that has a list of problems as long as my arm (if you want something tangible, it can't handle variable framerate). It's also the format of choice for high-quality rips of more regular content, both from new HD formats and even from DVDs - it has lower overhead, better tools, greater codec support, and is simply the best current container format by far. Of course there are a number of idiots who can't figure out how to play it, but that will be the case with any new technology.

    but the pirates do use it. its the defacto standard for scene released bluray rips in 720p and 1080p format, due to it being a convenient container for packaging multiple audio signals, subtitles and x264 encoded video and being all FOSS. its also a very popular format for anime, due mostly to its multiple audio and subtitle strengths.

    the piracy scene decided on x264 mkv for various reasons but wide compatibility probably wasnt one of them. potential for wide compatibility, open standards and high quality were probably bigger concerns. im pretty sure there werent any hardware xvid players around when they decided that that was the best option for dvdrips.

    the playstation 3 and xbox 360 can play x / h264 but not within the mkv container. this means its pretty simple and quick to convert on your pc, but more importantly it means that the console's hardware is fully capable of such playback, its merely a software limitation and this'll get sorted in time.

  22. Codec vs Container by coryking · · Score: 4, Interesting

    Took a while for that distinction to sink in. Here is another container format you'll be hearing about a lot more in the coming months. QAM and ATSC. QAM is only a signal modulation and can be used to stream any kind of container format--usually some variant of ATSC. Think of it, I guess, as like the low-level ethernet stuff--ethernet doesn't care if you use TCP/IP or IPX/SPX. ATSC is kind of like TCP/IP or IPX/SPX, it defines how information is sent over the low-level stuff, but for the most part it doesn't care what the information is (MPEG2, H.264). ATSC typically only carries MPEG2, but I guess it has been updated to carry H.264/MPEG4. I guess it can only carry AC-3 audio streams and not mp3.

    If you really want to force yourself to learn about video and audio codecs and containers, force yourself to use ffmpeg on the command line for a while. It's docs and number of switches can seem daunting at first, but just remember what you are trying to do is tell it what codecs to use, what bitrates to use, and any modification to the video/audio stream (aspect ratio, resolution, framerate, etc). If you type "ffmpeg -formats | less", you'll get a list of what your version of ffmpeg can read and what containers and codecs it can write to. Keep in mind not every container can hold all the codecs; you'll have to consult wikipedia for that. The whole exercise will make you think about every aspect of your transcoding experience.

      QAM is not a container format. It is a modulation scheme (as implied by the name).

      A QAM (in the video world) normally carries an MPEG Transport Stream, which is sort of like a container, except that it's a sequential stream. But the MPEG TS does carry a mux of video, audio, and data such as subtitles, so it would be more analogous to a container format than QAM in this context. And, in fact, there is a container format that is a direct sibling to the MPEG TS, the MPEG Program Stream, which is the "container" that DVDs use. (Sorta. File size limits prevent the use of an absolutely pure MPEG PS.)

      A container is used to cram all the components of a program into a random-access file. QAMs are linear streams, so the two don't directly correlate.

      Okay, having said all that I did a little research, and many do call a TS a container. Either way, a QAM certainly isn't one. Also, everything I said applies equally to ATSC. (Though ATSC is a standards body, so the waters are somewhat muddier.)

The whole idea is that if divx has accepted it for divx 7 then, it will be compatible with the next generation.

    Matroska has had spotty to non-existent support on many american portables because it is constantly evolving*. Divx will act as a periodic filter through which more stable releases can be made. Once the format can be made fixed for a year or two at a time, you will see more support.
