ATEME EAVC4 "The Ultimate H.264 Encoder" ?

Hello,

a quote from another thread:

People who have done visual comparisons say both encoders are similar visually.

What's written in the PDF linked in the quote above sounds quite nice.

So, is there anyone here who has done visual comparisons with "The Ultimate H.264 Encoder" ATEME EAVC4 ?

Or are there any comparison samples available showing EAVC4?

In my testing with any recent X264 build on a variety of content, X264 beats it in SSIM score (with or without --tune ssim) and significantly in performance (at least on my AMD Fx8350 @ 4.5ghz desktop). Apparently EAVC4 is supposed to be faster than X264, so their is a good chance it's simply not optimized for AMD's Piledriver arch. I'll need to test on my Sandy Bridge-E desktops.

Here is a clip I encoded with it:

If I get a chance, I'll try to upload the same clip I encoded with X264.

That being said, it's significantly better than any other commercial AVC encoder I've used. When I run into scenarios where I can't use x264, Ateme KFE w/ EAVC4 is a great non-free alternative.

EDIT** I forgot to mention, visually it's identical to X264. With X264 having a *slight* edge visually on very complex scenes; at least in my subjective view.

Can you share what bitrates at what frame sizes you were testing at?
