-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 transcode is another utility (CLI) that does the same thing as mencoder.
Also, mencoder works just fine on Ubuntu for me. I have never bench marked it, but in terms of output quality, it works well. If you have a PATA drive you may need to adjust your hdparm settings for your hard drive. You can realize significant IO throughput improvements if the existing settings are not optimised. The point is that the bottleneck may not be mencoder. Recent versions of Ubuntu seem to have reasonable defaults, so the tweaking does not gain as much as in the old Debian (famous/notorious for it's conservative hardware config). Media production work usually benefits from such tuning. My experiences with Ubuntu, especially recently, are the exact opposite of Roy's. While I can never guarantee that your experience will be the same, I do not hesitate to recommend Ubuntu. Roy Souther wrote: > mencoder > > mencoder is great for doing this sort of work.
