As a last resort you might just grab jpegs (that gives thousands of them in a few minutes, and streamer seems to be even faster then), and in parallel, record a 16 bit stereo wav-file (also with xawtv, of course). bcast can import jpeg-pictures, and you might render your high quality QT-movie from them along with good sound. (although it's not that simple, see bcast/docs/formats.html) The difference between a high quality jpeg (> 90% quality) and a raw picture seems more "academical" to me and can hardly be noticed at high frame rates. (and BTW, I do very well notice the difference between 8bit and 16bit sound encoding ;-). At least at higher resolutions (PAL) the performance bottleneck is definitely the I/O to the hard disks (especially with my fscking VIA chipset, despite ATA-100, and 27MB/s throughput). But if you swear by raw grabs, and/or high quality jpeg encoding eats to much CPU time and raw RGB is faster, then grab RGBs and convert them to high quality jpegs (100%, if you want) with a script like: #!/bin/bash for i in *.ppm do convert $i -quality 99 jpg:`basename $i .ppm `.jpg done "convert" is part of the ImageMagick suite, just in the unlikely case you haven't heard of it. With "convert" you can even do some image processing along with the conversion (do a "man convert"). happy grabbing, Amir C. Akhavan
