(version 2.2.0 from 19-12-03 by avisynth dev - sh0dan.)
page: http://cultact-server.novi.dk/kpo/huffyuv/huffyuv.html

QUOTE

* Added "Reduced resolution". This will save your file in HALF the orginal resolution, and upscale the video on the fly. Lossy, but very fast!
* HuffYUV is now storing interlaced mode in the AVI-file. Now interlaced files are properly decoded!
* Added MMX optimized YUV -> RGB conversion routines.
* HuffYUV will now suggest to store RGB32 (RGB with alpha), even if it is disabled. Alpha information will however be removed when on.
* HuffYUV should now support all resolutions flawlessly. Do however not that it is not recommended to use a resolution that isn't divideable by 8, when using Reduced Resolution, and YUY2 naturally must med divideable by 2.
* Minor General speedup of some internal routines. Should be a bit faster than older versions.

I'm really happy development on it continued, since there were some annoying bugs, which were never fixed.
If you don't depend on huffyuv's (incredible) speed CorePNG might be worth a look, too.

Heard anything about the other lossless codec out there? Alpineairy or somesuch I believe...

On the doom9-board there is a lossless codec floating around called "vble" by MarcFD. It internally uses the YV12 colour space which is also used in mpeg-2 and mpeg-4 codecs. It works pretty well and can spare you colourspace conversions.

I've readed (maybe here in HA) about one called:
Techsmith Ensharpen, for Quicktime... but I didnt proved it.

Great, I'm "collecting" lossless video codecs.

Incredible, an extra codec for cartoon fans!

From the codecs homepage:

QUOTE

CorePNG was orignally developed for use with the subtitles, it compresses cartoons and CGI very well and in many cases better than Huffyuv and Loco.

Tho it wasn't developed especially for cartoons, the PNG compression method is very effective on cartoons, like GIF too.

In most cases FFV1 is the most efficient lossless codec, often gives about half the datarate of Huffyuv, but it's much slower too (but still multiple times faster than CorePNG).

any links to win32 compiles? (i cant seem to google anything...)

It comes with ffvfw.

http://athos.leffe.dnsalias.com/ FFV1 it is part of the ffvfw package if you just use the VLC for entropy coding you may be able to use the codec for real time capture if you are lucky and have a reasonably fast computer. If you are really really lucky you might be able to use the CABAC that will drop the bitrate considerably maybe even 10-15% but I do warn you it is slow I can get approx. 18fps on my P4 1.8 Ghz so in order to use that for capturing you will have to have a smoking machine. Another interesting lossless codec is Milk by Marc FD here is a link MILK it is reasonably fast, faster than FFV1. Also there is VBLE which was mentioned earlier which is very fast

.
EDIT: Latexxx you beat me to it

tnx Latexxx & Bonzi. (my main usage for this type of codecs is vertical editing (intermidiates), and speed is the most important...)
