Congratulations to r0lZ. The explainations are very properly.

PSNR (in dB) is the mathematical right value describing the difference from the original.
I can remember that (global)

PSNR > 45 dB you cannot see any differences
PSNR > 44 dB very good
PSNR > 43 dB good
PSNR > 41 dB enough for grained sources

Use of CRF < 15 results in larger file sizes than the original.
Then you'd better use your original BD.

And I ask you, people: trust r0lZ. He has enough experience (since MPEG times). This is a thread about a 3D tool and not about basiscs of X264 encoding!
