What is the resolution of the starting files? If either of them are HD mpeg-4 files then there is not much you can do, and 100% cpu is what can be expected and there is really no way to fix it. Almost no effort is required on the re-encode, the bulk of the cpu time is the decoding part and depends on the original file's codec type, and the resolution of the original file. I have jobs to transcode 1080i and 720p and both transcode down to the same resolution and bit rate, but the 1080i is almost 2x slower because of the decode being much worse. ------------------------------------------------------------------------------ Register Now & Save for Velocity, the Web Performance & Operations Conference from O'Reilly Media.
