Avysinth showing double width for HEVC 10bits

[poisondeathray]

every little kid will understand my test, if you cant it is your problem......

Did you want to ask a kid to clarify it for you? or did you someone to explain it to you more clearly ?

B frames - Avg QP:19.38 size: 8754 (8bit) compared to Avg QP:30.96 size: 8831 (10bit) means that we have better 8 bit pictute quality for the same size of frame, so 10 bit produce worsе quality for the same bitrate which means that 10 bit have less compression on video

It does not indicate that . The quantizer scale is different between 8bit and 10bit ( a quantizer of say, 10, does not indicate the same thing between 8bit and 10bit) , and average QP is not a direct measure of "quality" . There is a positive relationship between lower quantizer and quality, but you cannot conclude anything from those numbers alone

--8bits (source) to 10bits is useless operation, you will get the same colors
--8bit has to be 4:2:0 and 10bit has to be 4:2:2
--10bit is nonsense because monitors are 8bit

all of the above are nonsenses, you keep people busy to remedy statesments like that

so no wander that one sentence of yours considering the same bitrate was overlooked. But, heck, op is talking about x265 10bit. To re-encode a library is not a good idea in the first place just because there is a new codec in town. Ok he has his reason , thinking space would shrink, hobby , do it for fun, whatever, If you want to help him take some 8bit H.264 video and encode it to 8bit H.264 and 10bit x265, otherwise you try to prove something that no one cares about in this thread.

Are you still on this guys ?

My purpose is to stream through plex and others my entire library. HEVC eats AVC at breakfast for this purpose. The visual quality of HEVC has improved a lot (not using GUI for my encodes but last stable builds), and as said, this guy is comparing AVC 8b to 10b encode while this thread is talking about HEVC, and while he is using the exact same settings for 10b and 8b. In fact the most often, the diff between 10b and 8b is around 12 AQP (63 quality limit for 8b and 51 quality limit for 10b), and the compression gain around 5%. But as said, it does affect banding too.

He does not even has a clue of what he is talking about (chroma mixing, 1080gtx not compatible, 10b vs 8b QP, i can go long but it's useless). It's like reinventing the wheel.
