Fast encoding with x264

[somespirit]

you don't know how MPEG-4 algorithm works (x264, h.264 is MPEG-4 how should be and Xvid is primitive mpeg-4)

me=dia is enough to catches all differences between frames (ie motion estimation) so P and B frames will use effectively all Reference spots in them

[somespirit]

here are my last adjustments for fast x264 encoding


we don't need I4x4 and P4x4 (red 2 on pic) macroblocks because we have I P B 8x8 and this is enough for motion estimation to work properly, if we have any 4x4 macroblocks it is double work for our CPU which we don't need

M.E. Range value of 8 is absolutely enough


next you can make 2 test encodings, one with these new settings and one with your previous settings on some short (~15 minutes) video with PSNR or SSIM calculation turned ON, so there will be no differences in PSNR or SSIM, but you will got more encoding speed.
