Russ, You can go crazy with any configurations you want; however, you'll notice the applied across the boxes will be uneven. I remember some machines doing nothing waiting for the others to be done with a job. However, that might have been because of the type of file I was rendering to, Quicktimes versus MPEGs. Now I'm remembering..with MPEGs, the files are rendered in different pieces numbered sequentially. After the render is done, you need to assemble those pieces of a video into the whole. Easy enough to do. Then you can script that process. I remember the experience being somewhat disappointing. But if you have the extra horsepower around and are encoding in large volumes, the renderfarm might meet your need. And you can only get so much joy (read: optimal performance) from the multithreading parameters in ffmpeg or mpeg2enc. ;) Life ain't perfect in the land of Linux video editing. (Callout to Doug Pollard's post of a couple weeks back). "It is what it is" unless you have the programming chops to fix it. scott _______________________________________________ Cinelerra mailing list Cinelerra@skolelinux.no https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
