It depends on what you plan to be a part of your "encoding". If you are just going straight from captured DV into mpeg2enc without any denoising or scaling, then Stephen's suggestion of multiple parallel runs is best. But, if you plan to run denoise, median, y4mspatial, y4mscaler, etc. before mpeg2enc, then something like netpipes (http://freshmeat.net/projects/netpipes/) will allow you to do this: Machine 1: dv to yuv -> machine 2 Machine 2: yuvdenoise -> machine 3 Machine 3: yuvmedian -> machine 4 Machine 4: y4mscaler -> machine 5 Machien 5: mpeg2enc Depending on frame sizes and options, denoise and/or median can often consume as much or more cpu time than mpeg2enc itself, so having them running on machines other than the one running mpeg2enc will speed things up overall. If you have 10 total machines, you could still have two of the above pipelines running in parallel, with each task having it's own machine to run upon. ------------------------------------------------------- SF.Net is sponsored by: Speed Start Your Linux Apps Now.
