Ssim

Which do you think will look better? both objectively (with psnr, ssim scores, difference masks & digital subtraction), or subjectively? ❋ Unknown (2010)

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. ❋ Unknown (2010)

This means for a given "quality" level; e.g. psnr or ssim, you might need 1. 3-1.5x the filesize for equivalent quality. ❋ Unknown (2009)

= 75% and window size around 8-16 seemed to work best for removal of gaussian white noise (in terms of resulting psnr and ssim). ❋ Great Dragon (2010)

: [OK] x264: SSE2Slow - pixel sad_aligned: [OK] - pixel ssd: [OK] - pixel satd: [OK] - pixel sa8d: [OK] - pixel var: [OK] - intra satd_x3: [OK] - intra sad_x3: [OK] - ssim: ❋ Unknown (2009)

i would like to say that your encoder is the best to hit higher ssim and psnr value ... it manages really well HD clip and it is really tunable (just i would like also 1pass vbr as in CCE beacuse i need for some test i'm doing ...) and its second pass it is amazing to goal the exact size i want!! ❋ Hank315 (2010)

h. 264 offers better compression than MPEG2, has clearly better objective measures (psnr, ssim) and subjective scores by a longshot (not even close here). ❋ Unknown (2010)

[Ew], why would [anyone] make a [sentence] with SSIMS? ❋ Ian Ter Netrole (2019)
