Actually, I have not been using the ffmpeg presets. I use the standard QT setting inside ffmpeg.
When I first tried this out when QT7 released, encoding h264 was very slow. Thats not the case now, even in QT. I think the H264 encodes faster than 3ivx from both ffmpeg expert settings and QT expert settings. Check out this file which I was able to really optimize: http://www.rocketboom.com/video/rb_05_nov_28_full.mov It is only 24megs. It encoded super fast.
