psnr

Maybe some psnr loss, but I really can not tell the differences between a fast 1st pass encoded movie and a normal 1st pass encoded movie (same bitrate).

If you were to make a plot, varying the bitrate on the x-axis, with psnr or ssim on the y-axis, MPEG2 never reaches the same quality at any bitrate, and never intersects the h. 264 line at any point (h. 264 eventually becomes lossless, MPEG2 does not). i.e. at any given bitrate, h. 264 will have better quality, or obtains a certain quality level at a lower bitrate.

Which do you think will look better? both objectively (with psnr, ssim scores, difference masks & digital subtraction), or subjectively?

If you measure speed at the same psnr i.e. the same quality level,
