Get a new watch? ;-) With out some numbers I find it very difficult to believe "4x slower". For full sized DVD frames around 5 to 6 frames/sec or so is normal with ~2.4GHz systems. Of course the time will depend on if you're using any of the filtering programs such as yuvdenoise. With a dual cpu system the filters will use up one cpu while the encoder uses the other (and a bit more since it's threaded). That would mean you were seeing 20 frames/sec with 1.6.1? I seriously doubt that - I'd like faster encoding but mpeg2enc has never gotten up to that range on 720x480 or 720x756(PAL) sized data. A couple things to make sure are being used are "-M 2" with the encoder, and put a buffering stage in front of the encoder. I use the 'bfr' program http://www.glines.org:8000/software/buffer.html something like " ... | bfr -10m | mpeg2enc ..." is the typical usage. If the encoder is stalling for input due to latency in earlier stages of the pipeline then 'bfr' will be of good value. Some timings of the same pipeline would be helpful of course ;) Cheers, Steven Schultz ------------------------------------------------------- This SF.net email is sponsored by: VM Ware With VMware you can run multiple operating systems on a single machine.
