The sort of jerkiness you are talking about is typically the result of 1 of 2 things: 1) Hard disk speed is too slow. To fix this, use hdparm to optimise your drive settings, or use a compression algorithm with higher compression ratios. 2) Your CPU is too slow to compress the video real-time. In this case, use a faster compression algorithm. (Possible 3: If you only get this when recording from a VCR, try the VCR hack that was posted to the list a while ago - this helps a lot if your VCRs playback timing is slightly off.) You may notice that these two are contradictory - so you need a fast HDD or a fast CPU, or preferably, both. I have an Athlon 600, and use DIVX4rec with the "-dq3" option. It never drops any frames, and the quality is still pretty good. On a PIII-800, I use "-dq 5", and the quality is awesome...) On my old K6-2 300 I had to use QTrec, and later convert to divx, but two lossy compression stages are a bit bad for quality. mp1e is the best low-cpu option I have ever seen, but I have had many problems with A/V synch. -justin _______________________________________________ Video4linux-list mailing list [EMAIL PROTECTED] https://listman.redhat.com/mailman/listinfo/video4linux-list
