On2 Releases VP6 video codec 111
A reader writes:"On2 Technologies, the folks who brought you the open-source VP3 video codec (now managed by Theora.org), have released our latest codec, VP6. Highlights include hi-def support with no encoder restrictions, real-time encoding at full D1 resolution, and substantial performance & quality improvements over VP5. Best of all: no "patent pooling" restrictions or external licensing fees, a la MPEG-4."

Doom9 shows us very nice screenshots from non-keyframes. The conclusion is still: XViD is the best codec around. I hope people understand that whatever other companies claim (e.g. "50% better compression") you should never underestimate what doom9 says: all codecs out there now are VERY similar. None of them is really outstanding.

I understand XviD's implementation of MPEG-4 is based on H.263.
So is anybody (including XviD) considering implementing it? I understand it isn't patent-encumbered. I could be wrong...

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.

XviD follows the MPEG-4 ASP (advanced simple profile) spec. Virtually all of the current major video codecs out there use some minor variant of this.
H.264 usually refers to the MPEG-4 AVC (advanced video coding) profile. This promises a 2-4x size improvement at similar quality to the ASP. However, it has one major problem...
So is anybody (including XviD) considering implementing it? I understand it isn't patent-encumbered. I could be wrong...
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.

At the moment though, if you wanna use this codec then you have to dance the dirty with Micro$oft, which is most certainally not free, or without restrictions. We use heaps of video on our sites, streaming, downloadable etc. and our primary concern is cross-compatibility.
So, nil point for ON2.
What about FFMPEG's MPEG4 Codec? (Score:2, Informative)

I'm sorry to say that I've yet to find a really satisfactory and impartial comparison, much less, one that is up to date. I've had to do all of my own testing to figure out what settings do, and how codecs compare. Mainly xvid, divx4/5, sbc, and ffvfw. As I stated earlier, I've found xvid in it's latest incarnations(Koepi [goe.net] and Umaniac's [hopto.org] versions are easy to find, and work great, in my experience) are the best, and the doom9 xvid forum is a great place to give feedback to, and get information from, the creators of this robust and customizeable codec.
This [digitalinsanity.ath.cx] is probably the closest thing I could find to an impartial comparison, displaying unpostprocessed, and postprocessed images from many different codecs. Unfortunately, when I tried the link, it didn't respond, hopefully it will be back up.
Hope it helps.

Since I've never come across On2-encoded video I suspect that this codec isn't worth the hassle.

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).

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.

FWIW, H.263 is the standard video codec used in videoconferencing system. Most of the IRAQ video was using it.
All MPEG-4 codecs are patent-encumbered, and will require license fees in some circumstances. However, these tend not to be too onerous. For example, today's MPEG-4 video codecs are free for the first 50,000 units distributed per year.

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.

I hardly think this matters for professional encoding. There are real-time H.264 hardware encoders in development by VideoLocus [videolocus.com] and Sand Video [sandvideo.com].
Besides, it took quite a while for the old MPEG-2 and MPEG-4 reference encoders to be anything but dog slow, so I have no doubt that in a years time we'll see at least a 4x speed up with software optimization. Add that to the 2x hardware speed up and you have something that starts to look viable for quite a few applications.
