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 |

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. |

| IR2.x

vidc:IV2.0
to
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. |

| 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. |

| IR5.x
|
vidc:IV5.1
to
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. |
