codec that compresses better than huffyuv?

[junglemike]

hello everyone.
I'm trying to compress video using bt848 card. Resolution is 768x576.
huffyuv is good solution cos: 1) it's soseless 2)it almost doesn't take cpu power (on celeron 1700 only 15% with 768x576) But this is not applicable for me because i don't have so much space. To compress 3-4 hour show i should have something like 40-60gb free which i don't have. Mjpeg codec ,if i understand i correctly ,is "almost" loseless with q-ty 19/20. But it still generates too big files. So is there any codec wich is loseless or "almost" loseless from one point, and generates smaller files by compensating it with more cpu usage.
I tried Xvid, with 1pass,cbr,bitrate=4000, max i interval=10/5/1(!),no bframes,no chroma,no lumi,no qpel,motion serch=5/4. Xvid is good, very good, i can't see any artifacts, but the problem - it is too heavy for my cpu,in 768x576 i drop many frames, only with 480x360 or 352x288 i can still compress without dropped frames.
So my question is - is there some codec that compresses better than huffyuv and/maybe (as a side effect) takes more cpu power than huffyuv, but not so much like xivd/other mpeg4.
I'm a newbie in this issue. So your opinion is appreciated.

DV

MAINCONCEPT DV ARE THE MOST FASTER.

But only 720x576 wll be avaliable to u

You could try divx5, setting the keyframes to 1 (every frame)
and the bitrate to the 10k (maximum)

Try Morgan mjpeg v3.009. Start with a setting of 90% and see what quality/file size you have and then adjust as necessary.

Follow the link in my sig and look in the codecs category of the A/V links. There are a few there. 2 or 3 claim to be better (faster/smaller) than HuffYUV. If you've got space, DV is great. Don't worry about the large format, you'll resize anyhow if you want quality.

I've also just started trying out VBLE by Marc FD. It's a lossless codec but it works in YV12 so there's no need to convert to YUY2 when using AVIsynth 2.5. I've just done a 80 min capture (24 in Widescreen) and the compression ratio was 4.9:1. It's still in beta but the results so far seem pretty good.
