for any quanity of video capture would require hardware compression, not only for the disk space but software MPEG requires many times real time to compress. A year or so ago, I was planning on supporting a MPEG chipset but the project money went elsewhere. from the weekly computer rags a couple years ago, the MPEG-1 chipsets have really dropped in price. Hopefully the finished board are becoming cheaper than the $4000 a professor here paid for a Windows based hardware video conference board (it included IDSN adapters, camera, microphone, and conferencing sofware that jacked up the price) . The capture to file software is (purposely?) limited to approximately 15 minutes of program recording. MPEG-1 chipsets support would be very nice for MBONE appilications, because it is becoming a popular format...software encoding the current H.261 format limits the frame rate on the less powerful machines. MPEG-2 chipsets are much more costly and require more disk bandwidth and space. The advantage of MPEG-2 would be HDTV compatibility especially if a video mixer was being developed. --mark tinguely.
