That is, I take the video into MJPEG (with one of the higher rate settings, from 7 to 20 megabits/sec) and compress it with an MPEG encoder to 600 to 2500 kilobits/sec. Note that MJPEG is an editable format and not really targeted for network nor distribution format. > > The only downside as far as I can see for this card is, it requires I run > windows :) Has anyone else looked at this card? > The only real problem here is that the windows drivers leak memory like hell. Doing a 15 minute capture renders my 64 meg machine out of memory. So if anyone would be doing a capture utility for FreeBSD I'll definetly switch over. The card also does MPEG-1 and MJPEG hardware decode. Pete
