Proper size, but not modest quality!

The reason of x264 10 bits encoding.
01:15:55~01:16:20 gradations in the dark part

Compare with it x264 8 bits automated 2 pass ending.

Once more!
Until now x265 10 bits or 12 bits encoding makes the best quality, but it takes very, very, very long time. Megui x264 8 bits encoding is still good in time efficiency, but with this suource it's output is awful at special place. So, Megui x264 10 bits encoding is the proper alternative in time efficiency and quality efficiency, ironically abr's quality is better than automated 2 pass encoding.

Use potplayer, mpc, etc, which supports 10 bits decoding. And there is no playback stuttery. Pls reply only encoding quality of video & audio.
