H.264 Encoding Performance

H.264 encoding a 40 minute video at 720x480 resolution and medium quality from iMovie on my 1 Ghz PowerBooks is taking close to 30 hours! I have single-pass encoding turned on; it's normally meant for draft and live encodings. Is this normal? How can QuickTime Broadcaster possibly stream this codec live? Am I missing something? I wish Quicktime supported distributed encoding so I could team up with some Mac weilding co-workers and utilize their idle cycles. Maybe I could throw something together. After all this waiting, I hope it turns out okay.

Bob, you really can't do H.264 on the Powerbooks. That computer may not be able to even play that back at full speed. Get yourself one of the x86 devkits to tide you over until they ship an x86 Powerbook.

BTW, congratulations!

I halved the video size and now it's only taking a few hours. Still doing single pass.

An x86 developer kit is an awesome idea. Do they have iMovie/Quicktime builds for x86 yet?
