ANIM 	RDX 	Intel 	?
AP41 	AngelPotion Definitive 	AngelPotion 	Another hacked version of Microsoft's MP43 codec.

CDVC 	Canopus DV Codec 	Canopus 	Allegedly used with digital video cameras.

Existing video software, such as Windows® Media Player® and Ulead Media Studio® can utilize this codec to play, create, convert and edit."
LBYR 	? 	? 	Based on the naming, I would hazard a guess that this describes some Bayer image format and may have been registered by LEAD Technologies. Can anyone confirm or deny?
LCMW 	LEAD MCMW Video Codec 	LEAD Technologies 	This is a wavelet-based codec. LEAD tell me "The MCMW Codec is designed to create high-quality video using low bandwidth (dial-up) delivery.

PJPG 	PA MJPEG 	Pierre Albou 	Non-standard codec based on MJPEG.
PVEZ 	PowerEZ 	Horizons Technology 	TrueMotion based codec (?) It appears that Horizons Technology has now been acquired by Raytheon and is no longer in the codec business (can someone confirm this - their URL is now redirected). Allegedly, you can download this codec from support.private.com but I'm not going to add a link since this is an adult video company and I don't want to get this site associated with porn.

raw 	Raw RGB 	? 	Apparently this contains "raw, uncompressed RGB bitmaps".
RGBT 	32 bit support 	Computer Concepts 	That's odd. I registered RGBT at the same time as a bunch of other FOURCCs and it was granted. The format I registered is for 16- and 32-bit uncompressed RBG images with a transparency plane. Microsoft's codec site, however, lists Computer Concepts rather than Brooktree (Conexant) as the owner. Hmm...

RPZA 	Apple Video 	Apple 	RGB555 block-based codec used in Quicktime files.
RT21 	Real Time Video 2.1 	Intel 	What Indeo was called before the marketing guys got their hands on it. RTV or Real Time Video was the format produced by Intel's ActionMedia II adapter back in the late 80s. When the 80486 came along, this migrated to the software-decodable Indeo formats used today.
rv20 	RealVideo G2 	Real 	RealVideo G2 (6.0 and greater versions of the player and encoder)
rv30 	RealVideo 8 	Real

YUV Codec 	Tekram International 	YUV422 codec shipped as part of the driver package for Tekram's C210 product.
SAN3 	DivX 3 	? 	A direct copy of DivX 3.11a, apparently. If you use a FOURCC changer tool on these AVIs they will play with the standard DivX codecs.

SMSD 	Proprietary codec 	Radius 	?
smsv 	Wavelet Video 	WorldConnect
SP40 	? 	SunPlus 	Appears to be an uncompressed YUV format of some kind but I have no information on this other than that.
SP44 	? 	SunPlus 	Presumably a precursor to SP54?
SP54 	? 	SunPlus 	Apparently a form of MJPEG but with some header or other missing. Software shipped with a number of low end digital cameras and webcams such as Aiptek's Pocketcam digital still camera, Logitech's ClickSmart and Mustek's gSmart mini 2 use this format. These use SunPlus chipsets so presumably this explains the "SP".

VGPX 	VideoGramPix 	Alaris 	Alaris VGPixel 32-bit AVI compression driver. It seems that this codec is installed along with the software for the "Alaris Wee Cam."  The codec doesn't appear to be available separately but, allegedly, works fine if you install the Wee Cam software even without the camera. You may also find some information at http://www.alaris.com/vg_tech/vg_tchtx.htm and http://www.videogram.com.

VP30 	VP3 	On2 	On2 tell me "On2's VP3 codec will encode video into a VP3 file in multiple bit rates (roughly 220 Kbps, 330 Kbps, and 440 Kbps) and at optimum frame rates (usually 29.97 fps). This multiple bit rate file allows the TrueCast server to scale dynamically and smoothly as bandwidth congestion increases and decreases, providing the viewer with a consistent and reliable experience, without choppiness or interruption."
VP31 	VP31 	On2 	The successor to VP30. This algorithm was open sourced by On2 in 2001-2002 and is the basis for the Theora Video Codec. Technical details are available here.

Y411 	YUV 4:1:1 	Microsoft 	Supposedly 16bpp packed but 4:1:1 is usually 12bpp - odd. This is an uncompressed YUV format.
Y41P 	Brooktree YUV 4:1:1 	Conexant 	This is an uncompressed YUV 411 format I registered about 7 years ago. I've stumbled on a few AVIs that use it, though, so I am listing it here.

I'm told "VirtualDub has been able to decode YUY2 internally since V1.3a. Newer versions of Ben Rudiak-Gould's Huffyuv codec will also convert YUY2 or UYVY data to RGB"
YUYV 	? 	Canopus 	Compressed YUV format. Some of the software on the Canopus download page may include this codec (I'm guessing - please tell me if this is true).
