Darn - I forgot that 'quality' is not a 0 thru 1.0 number but is scaled by 100. Too many different ranges/scales :) (640 * 480 * 29.97 * 100) / (200 * 1024) gives 4495 or about 4495 * 8 kbits/sec (~35900kbits/sec). About half again as much as DV. With audio at ~1500kbits/sec (187 kbytes/sec) a total rate would be around 4680 or so. That's 4680 kbytes/sec is a long ways from 10 or 11Megabytes/sec. I was curious if 'raid-0' was strictly necessary for capturing. With rates in the ~4-5 megabyte/sec range it would seem that thruput isn't the primary reason for a raid-0 setup. Quite useful for catenating drives together into a bigger filesystem though ;) Cheers, Steven Schultz ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ Mjpeg-users mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/mjpeg-users
