If you suspect that one of the codecs are missing from your machine, click on the "Test" active link to the right of the codec type and it will load a standardized 3 second clip using that codec. The last column contains the known information as to where to get the codec. CODECs marked by GREEN BACKGROUNDS are those that were not designed by their makers to be shared between machines.  While many a downloader has added these codecs, DO SO AT YOUR OWN RISK!

H.261/H.263 are first and second generation video encoding. Targeted at ISDN speeds, they support video over links with bandwidth available in 64-kbps increments (compared with the 1.5Mps of MPEG). They use DCT, quantization, and interframe compression. M$ supplies versions of each (the M) for decoding, based on the same core of H. M$ says that M263 should download and play I263, but I've yet to see it.

Huffyuv
vidc:HFYU by Ben Rudiak-Gould. Huffyuv is intended as a replacement for uncompressed YUV video capture. It's very a very fast, lossless Win32 video codec that some of the long time cappers use for their captures. Not used too much as a "viewing codec", but a great advantage for those with older machines but fast hard drives

I263
vidc:I263  I.263 -- by Intel ( a varient of H263 ) 
I263 was a codec developed from H263 by Intel for use with their"Create & Share" video conference capture card.  Because, for it's time,  it's high compression rate and its' ability to be inserted into the Windows codec list, other posters started using it as well.  It was never intended by Intel to be distributed, but to be used only by those wanting to video conference.
Available here for Win9x and Me and WinNt/2000/Xp. Instructions are inside the zips.

vidc:IV2.2
IR2.x by Intel One of the first codecs by Intel to catch on, IR2.x was developed into IR3.x, and they both shared using the Vector Quantization algorithm.  16 bit colour structure. Due to some incompatability problems during the development of IR4, it was removed from the bundled codec package. Available here as a zip file. Test IR2
Patch
IR3.x
vidc:IV3.1
to
vidc:IV3.3
Developed from IR2.x. When 4.1 came out, Intel replaced the 3.2 codec with a new version, but kept the version number the same.  While backwardly compatible, the reverse is not true.

IR4.x
vidc:IV4.1
to
vidc:IV4.5
IR4.x .  Marks the changeover to a Wavelet based algorithm.  Primary porpose of this change was, as the name implies, for these codecs to be used in streamingweb videos.  Like the versions before it, still based on YUV9, so many cappers with the Intel Smart Recorder II and III ( as well as other's whoose cards use Intel's YUV9 based capture chip ) found this an ideal codec to compress in.

vidc:IV5.2
IR5.x Better referred to as IVI - Indeo Video Interactive. Development Has been Discontinued by Ligos, and as of Xp with Service Pack 1 (Sp1), is no longer included with Windows. There is no known problem with this codec being installed in Xp, but don't until you just need to.
