Following your data and since ".. P1, P2 and P3 are essentially the same .." you could also say that P1 is optimal for you.  Tongue

As a side notes:
  • I hope you are aware that if you did your testings only for one sample it's probably only true for that sample. Wink
  • Both psrn and ssim doen't always align with human perception.

I performed the same tests with other movies, and the figures obtained are different for every movie, but was does not change is the fact that the quality and size of movie encoded with P1, P2 and P3 are the same. I selected P3 hoping that a day it will be implemented some difference in the encoding of P1, P2 and P3, in this case P3 is the more conservative choice. Another common behavior across all the encoded movies is that the encoding BitRate is a decreasing function of preset (i.e. P1 has higher BitRate of P4 and P4 has an higher BitRate of P5 and so on...). But for some movie I found that P1, P2 and P3 don't only have the higher BitRate but also the best figures of SSIM and PSNR. Of course you are free to perform your own test to make you your opinion.  Tongue
