This is the best one for exporting with x264 out of QuickTime. Using straight default settings, output files match the color and gamma of the uncompressed source more accurately than the other x264Encoder here on MacUpdate.

Update: The other x264Encoder on MacUpdate has advantages over this codec when viewing exports on a PC. If maintaining color/gamma is a priority for your exports, consider where the files will be viewed and test both encoders to see what gives you a better result.

Anyone have any experience using this codec to produce iPod Classic-compatible files? Can it add the atom? I'm looking for a good replacement for the built-in H.264 encoder for exporting from EyeTV, and this seems the most likely candidate.
The developer's Berlios website has no relevant forum posts (or any beyond 2007 for that matter), no wiki, no documentation and no home-page, so I thought I might get a better response here (also I really didn't want to create a user account for yet another website…)
Thanks.

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!

(Mac OSX 10.4.8, MacBook Pro 2.16GHz Intel Core Duo, iMovie HD 6.0.3)

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.

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.

This looks very promising for an first release. However it does seem to always fail on Multi-Pass encodes at the moment. Single-Pass encodes work well, but here there is no speed difference over the Apple codec yet, perhaps we will see this in the Multi-Pass encodes once they are working more smoothly?

Would be great to have little '?' buttons next to each feature which bring up a small pop-up utility window and an explanation of that particular encode option.

Thanks for this new Mac codec, x264 is widely regarded as the best quality H264 codec around, so it will be great to have this on the Mac!
