      Right up to the point where they download their first XviD video file. Then, like anyone else, they'll pay the price and install the darn codec (after posting on countless message boards asking why the heck their video won't play).

      It's a necessity thing. Nobody wants to install what they don't need. However, the people who *make* videos experiment all the time to get the best quality they can...and once that happens, the others are forced to follow.

        Ffdshow [sourceforge.net] is a filter for most mpeg4 codecs. Works with divx 4,5, xvid and other mpeg4 implementations. If all you do is playback, no codec required. Also if use alpha xvid codecs and it doesn't playback properly with ffdshow, you know that your vid isn't mpeg4 compliant. Btw, I capture/encode shows all the time in windows and would like to do this in linux, but it seems really lacking. First off, avisynth [avisynth.org] is an indispensable tool for dealing with video. What first attracted me to it was the best ivtc plugin by Donald Graft [mordor.net]. This processes telecined sources back to their original film frame rate which I use on toons/film sources.

        But the versatility goes way beyond that. Here's an animated menu [cultact-server.novi.dk] I made for batman tas for a vcd I was working on, which btw I authored with videopack 5 to include animated menus, galleries with audio and chapter selection (I love pimpin that :) ).

        Also worth mentioning is Tmpgenc [tmpgenc.net], probably the best mpeg 1 encoder, which is free. And not to shabby mpeg2 encoding. Also of course is virtualdub [virtualdub.org], which has come in handy on many occasions.

        So where are the comparable linux equivalents? I couldn't find them. I'd love to see a write up on video encoding on linux, maybe I'll do one myself.

          Ffdshow is an easy replacement, as it's based on a Linux project, ffmpeg [sourceforge.net].

          The extent of my encoding comes from recording TV or VHS tapes and throwing a few filters at them for cleanup and encoding. So I've never had a chance to become familiar with what features avisynth has. Some people over at Doom9's Linux forum have mentioned getting Avisynth running in wine [doom9.org].

          Tmpgenc should be a pretty easy replacement. Transcode [uni-goettingen.de] seems to be a favorite for mpeg2 encoding. There was a problem when I first started using Linux, which slowed mpeg encoding to a snails pace for a while, and I've never found a chance to get back to see how it works when fully functional. A lot of peoplel swear by it though, and it's feature list is pretty impressive. Avidemux, as well as quite a few other programs also provide mpeg1 encoding, I think through ffmpeg.

          Everything in VirtualDub/VirtualDubMod except video capture should work fine under wine and that's what I used for quite a while before Avidemux [fixounet.free.fr] appeared. The design and functionality are very similar to virtualdub, and it also includes encoding to mpeg1.

          One of the two best media players for Linux, Mplayer [mplayerhq.hu], should be noted to have better support for matroska [matroska.org], in cvs, than is available for the format under windows. And these [bunkus.org] tools can be used for creation and editing of matroska files.

          For capture from a tv card, I use nuppelvideo [tuwien.ac.at], and then use avidemux to edit and convert to a smaller format.

        There are no XviD video files. Currently most video files are:
        AVI Container
        MPEG-4 Video Track
        MP3 Audio Track

        The difference between DivX files and XviD files is the FourCC ("Four Character Code" or something).
        DivX and XviD are just differernt encoders, not different formats. Just like LAME and FhG MP3Enc are differend encoders, but produce the same format.
        If you change the FourCC from ''XVID'' to ''DIVX'' the normal DivX codec should be able to play it (I've never heard of any problems).
        That's why I think, the people who encoded the video file should change the FourCC to DIVX, try to decode the file using DivX, and (if it works without problems) release the file with the DIVX FourCC.
        This way you can reach a wider audiance.

      Doom9 is a good site to get news on about what codecs and applications are new, or releasing new versions. It's also a good place for discussion with the developers of many open source applications and codecs/video containers. However, I'd recommend that if you read their video codec reviews, you keep several things in mind. Firstly, the review is very subjective, and though I agree with the conclusion (xvid does the best job in my experience) the reviewer isn't exactly doing a normal comparison. Secondly, they're not very open to criticism, constructive or otherwise, and seem to have the attitude that they are THE EXPERTS on video encoding and codecs, and are thus beyond reproach, although, from what I can tell, the site owners aren't actually actively involved in the development of any codecs or applications. The main two flaws of the review are: A. they use post processing in all of their comparison screenshots and the reviewer used post processed shots to determine which he thought looked best. That in itself pretty much invalidates the results, as the actual output of the codecs isn't the only thing being tested, but also the perceptual quality of their respective post-filtering schemes. B. he was using a special version of xvid that's not available to the public, and that many of the people involved in xvid didn't even realize existed, which, once again completely invalidates his results for the rest of us. So, like I said, good site, great news, even greater discussion, questionable codec review.

"special version" - there are thousands of "special versions" of Xvid, every build by every person who releases builds is a special version... it's in development, that's what CVS is for.

        Yes, an AVC implementation exists [hydrogenaudio.org], but it provides its own demonstration of why no one uses it yet despite the improved size and/or quality... Namely, 30-45 seconds per frame at encode time. For a full-length movie, that comes out to two or three days for a single-pass encode.

        Additionally, even if you feel inclined to wait that long for the sake of quality (personally, I would), the link I gave above points to more of a proof of concept than a "real" viable codec. It needs quite a lot of tweaking just to make it compare to existing ASP codecs such as XviD.

      No doubt On2 has filed patents on VP6. Their pitch is that all the patents are (supposedly) owned by them instead of 20 different companies, so it's easier to negotiate a license. Of course, if you aren't willing to pay licensing fees at all then it doesn't make any difference.

  • 3D ideas in movie codecs? (Score:3, Interesting)

    AFAIK, many video codecs use some kind of FFT/DCT/wavelet compression for individual frames, and then some rather different techniques to account for the similarities/changes between subsequent frames. As a physicist I find this rather too complicated; it would be more natural to treat time as a third dimension, and just use FFT/DCT/wavelets or whatever for the whole 3D package (probably split into NxNxN cubes).

    Quick googling shows that such codecs have in fact been investigated. But are these ideas used in any current codecs?

    Of course every lossy codec has its problems, but there's at least one reason why I'm intrigued by these 3D style codecs: it could be easier to balance resources between single-frame precision vs. motion. With fast action we're less sensitive to details, so the codec could use more information for motion and less for the image details. And vice versa for slow scenes. This would happen automatically if the codec always preserved the strongest percentage of frequency/wavelet components (which is a standard way of signal de-noising).

    • Current video compression techniques use lossy compression schemes, which are based on removing elements that are perceptually less important.

      In a movie, human perception for intra-picture elements (2D picture) is not the same as inter-picture (variation over time). The elements that can be eliminated are quite different and that is why you get better results by applying different techniques for compressing each of them.

      For example: imagine a static wall painted with a single color. A "distortion" that ch

    • I've discussed this with friends as well while taking classes on image processing and such. Not sure why there are no such codecs in existance though.

      It would seem like wavelet would be a good candidate as it's quite easy to "shave off" coefficients to try different compression rates. But considering that there are no such codecs I'd assume that there are reasons for it. I haven't heard or read any though.
    • Well, such a scheme might produce somewhat better compression (especially since the impulse responses of visual neurons resemble 3d wavelets, naturally suggesting a 3d scheme for efficient representation.) I once implemented a scheme using 3d wavelets for optic flow detection, with some pretty good results on canned data.

      The drawback is that it requires more complicated encoders and decoders, which use more memory and more memory bandwidth due to the need to decode several frames at once. Today's hardware

    does anyone else get the idea that all these new better more innovative codecs are seriously damaging the overall encoding scene? sure, all the computer users can just go download the latest nemo codec pack, but stand alone players trying to support all these new different formats are being over run by a army of different codecs. ultimately we doom ourselves.

      I don't care about the special effects, give me a large sheet and a hurricane lamp and I can show you love scenes that'll blow your mind.

      Seriously I have no problem with the concept of hundreds of codecs out there. Most of them are small niche type objects that don't affect me or the TV Station that I work for. We stick with MPEG and AVI and we have no problems.

    Another poster pointed out that this codec isn't free, and is just as commercial and proprietry as Real and WMV. They're wrong - it's actually much worse than those in terms of cost and lock-in.

    Now, I don't know what the terms are for VP6, but our company investigated implementing VP5 a while back. To encode in realtime, you needed dedicated hardware ($15,000 per license). To encode offline, you need software at $10,000 per license. This is licensed on a rolling annual basis - i.e. $10,000 a year. You then additionally need to license the TrueCast on-demand server to distribute content, which is similarly priced.

    I'd expect VP6 to be similarly priced to VP5. You'd better be encoding an awful lot of video and saving an awful lot of bandwidth to make it worth your while.

    OTOH, the quality of VP5 was extremely good for a given bandwidth (much better than xvid).

    • You'd better be encoding an awful lot of video and saving an awful lot of bandwidth to make it worth your while.

      It seems that AOL thinks it's worth the money [on2.com]. Probably because they very well may be doing huge ammounts of encoding. Maybe the AOL-TimeWarner merger will begin to yeild something interesting.

      • You can play back VP5 in software happily, but you can't encode in realtime. I doubt very much you can encode MPEG-2 in realtime, and that's a much simpler algorithm.

        So you've laid out $10,000 for an encoder license then?

        Shoutcast/icecast will stream VP3, not VP5. I think you've confused the two. You might like to check out On2's page on VP5 system requirements [on2.com]. You'll notice that the realtime VP5 encoder is still "coming soon". I suspect now VP6 is out, it'll stay that way.
  • The linked article is generally pretty good, but I found one rather glaring omission. When testing AVC (called H.26L in the artcle), they only used a single reference frames. One of the most important features of AVC is its support for multiple reference frames. These work by allowing the codec to do motion estimation from multiple previous frames (3 in the baseline profile, 5 in the higher profiles). This helps compression efficiency a lot with things like muzzle flashes, spinning fans, or anything else w
