OBCD ADAM  The best one for moment,

not enought functions (noise and motion estimation will be nice),

b-frames pyramids not work even with avc decoder ??  (Version 1.1)

CHOADYJPM  I like it. I just started encoding on my MacBook Pro and I'm getting great results! I am having one fairly large problem.... It works fine with Quicktime export but if I use iMovie HD and try to export with it it crashes my iMovie app!!! Even if I try to go in and change it in the Video Settings and change to a different codec, it crashes. So I have to go back into Quicktime to change it before I can go back into iMovie and export to Quicktime Movie again. :( Idonno if anyone else is having that issue or if it's just my machine.

If not for that annoying bug I think it is totally awesome!

WINGS  Hey, this is good. I re-encoded an 8.4MB 50-second 320x240 mpeg1 clip into h.264 using Quicktime's standard encoder and x264. Here's what I got:

With QT h264 I set the encode to High, data rate to Automatic. File size turned out to be 7.3MB and it took 55 seconds.

With x264 I had to set the quality to Medium-High to acheive roughly the same file size (setting it to High like in h264 encode resulted in a large file, 20-something MB). It took 45 seconds and generated a 6.3MB file.

The x264 was noticably better. It wasn't WOW! better but it was definately better. You had to look hard to notice that either of them were not as good as the original. And x264 did it with a smaller file. I like it. Nice going, whoever did this.  (Version 1.1)

YNOT  Needs to have the user authenticate to install, which it does not seem to do currently. This is because it is adding something to the system software and could potentially be dangerous (not that it is), but as a matter of process.  (Version 1.1)
