Re: 720p50 3500kbps twitch.tv OBS

I have default cpu clock speed.I try your settings "x264 CBR
3800kbps Bitrate
800kb buffer
Keyframe Intervall "2"
"veryfast" or "faster"
"baseline" or "main"
tune: "off" or "animation"
x264options: "level=4.2 vbv-init=0.25 ref=3 deblock=-3:2 me=hex merange=24 subme=3 rc-lookahead=0 lookahead_threads=0"

all fine but lot of pixels how i can fix it? change buffer size or bitrate? faster preset eat my 10-15%cpu its ok.

Re: 720p50 3500kbps twitch.tv OBS

use "baseline" and "faster"

actually for 3800kbps and 800kb buffer you need stable 5MBit/s upload

i will test 720p60@3200kbps with 600kb buffer

have in mind CSGO is a game with very fast changing scenes - those games with low bitrate usually get pretty pixely - but i try to find your sweetspot

4-7 stable upload

video on 3800 buffer 800 

Twitch 

lot of  grass and pixels

mh, i dont have rust - but it looks hard to encode. try "fast" cpu-preset
and i try to improve custom encoder settings with a similar game and your settings

give me 2-3 days for that

Re: 720p50 3500kbps twitch.tv OBS

thanks !

p.s. i try fast on 3800 and bufer 800 same quality like faster

+ i disable , uncheck - Dinamically change bitrate to manage congestion ( beta ) and my stream quality stays better.But in OBS i see sometime 0.2% frame drop is critically ?

Re: 720p50 3500kbps twitch.tv OBS

dropped frames happen for you because you need to reduce bitrate and buffer a little - try 3500kbps + 600kb - this will result in max 4MBit/s instead of 4.5MBit/s

dont activate that option

Re: 720p50 3500kbps twitch.tv OBS

So help me out here, trying make a rx5700xt endoder look good (ish) on cod warzone specifically in 810, and 860 downscale streaming to twitch. Why? To say i can because im a rabid amd fanboy with a bunch of nvidia buddies rubbing their nvenc chips in my face. Main thing i need to solve is when i turn rapidly, i get pixelation, and obviosly when im by the grass and trees on the map, same problem. Any advice would be superb. Can i do x264? Yes....but i have a specific goal here so i wont be. I can throw whatever bitrate needed at obs just fine, but i assume theres more to it than that

Re: 720p50 3500kbps twitch.tv OBS

here a quick summary of quality with 6000kbps bitrate and all 4 Encoders:

x264: 100%
NVenc: 94%
AMD AMF: 92%
Inten QSV: 90%

best settings for 810p60 or 860p60 with AMD AMF:

ah i see - WHY do you want to use AMD AMF when you can use x264?
x264 has BETTER quality than AMD AMF - especially if you use limited bitrate!

there is no need to use AMF when you want best quality for your stream on a AMD 6C/12T CPU
