Largarith is better by far than Huffy ever was and doesn't have the bugs that Huffy versions suffer from http://lags.leetcode.net/codec.html
Better to capture always using a lossless compressor for SD that I guess you are working with. Any pc that is P3, P4 (or equivalent AMD pc) or higher specification for SD maybe even HD video should be able to capture fine to a lossless video and audio. Important to have right is the capture setup and capture device hardware drivers that work correctly for the capture. Having any of those wrong likely make the capture task harder or impossible
As said previously capture to an avi lossless intermediate file such as Largarith then any need to editing or filter work after capture can be done with retaining greater percentage of video quality (depending video filters applied during editing)
Xvid is lossy compression read more here for other video compressors http://en.wikipedia.org/wiki/Comparison_of...of_video_codecs
Capture video with lossy compressing when no further editing or filter need to be applied after capture. Do capturing some video first to determine the final video quality of the lossy capture |

IMHO of the lossless codecs, Huffyuv is most widely compatible, very reliable, is *sometimes* fastest, and yields the least compression. Not saying one codec is always better than the other, just that there are uses for each.

EDIT Noting meowmeow's post below, MJPEG is even more widely compatible with media players & editors than Huffyuv (although MJPEG decoders sometimes disagree on colors); at maximum quality (q=1) it looks very good; and it is versatile - you can set your desired quality/size tradeoff over a wide range. It's not as fast as Huff/Lags/UTVideo. FFV1 has not been fast in my experience - others disagree.

Alternatives to Huffy:
Lagarith - lossless multithreaded. Fast compress and decompress - no delta frames.
x264 lossless setting - multithreaded. Fast or slow. Delta frames* for higher compression.
FFMpeg/FFDshow codecs:
ffv1 - Lossless with delta frames* for higher compression than "Huffy"
MJPEG. Lossy, no delta frames. Natively supported by VirtualDub.
DV - no info.
*Delta frames might give slower decompess with non-linear processing filters. |
