Has anybody tried these yet?

I tried the AVC1 decoder. It comes with a preference pane for setting post processing.

I couldn't tell the difference from QT's AVC/H264 decoder so I removed the component... But I also never tried very hard.

I've started using mp4vEncoder. It's very good quality and its integration with Quicktime gives certain options compared to ffmpegX. It is very slow, though, on my Mac Pro, even distributing across four cores. There is no rate indicator, but it would be not much faster than real time, I don't think. I'll do some better guestimates.
