[x264-devel] Defining video quality

While comparing x264 with JM (10.2) I had been using PSNR for comparing 
the qualities of the two encoders. I understand JM is an encoder 
designed to achieve better PSNR rather than track true motion, or 
increase texture detail. I was wondering if x264 was based on a similar 
theory?
Also, what other metrics are usually being used in the industry to 
define video quality, since PSNR can be misleading at times. Any 
pointers/comments?

Thanks
Axel
