Question / Help custom x264 options for low CPU load

[Benman2785]

Hi,

EDIT: (new settings)

here my low cpu usage settings for "strict" streaming ~5000kbps 720p60
its a baseline/high/(very)faster-chimera

x264 Options:

level=3.2 no-cabac=1 ref=1 bframes=0 direct=spatial deblock=-3:2 no-mbtree=1 me=umh subme=2 sync-lookahead=0 rc-lookahead=0 trellis=0 weightp=0 aq-mode=1 aq-strength=1.20 threads=3

with Ryzen 2600X @4.2GHz i have 10-15% load
here you can see a test: http://youtu.be/kamEtzFPMR4

Level 5.1 seems a little unnecessary for 720p60, 4.1 is what twitch recommends

correct and actually 3.2 is for 720p60 ( http://de.wikipedia.org/wiki/H.264#Level )
4.2 for 1080p60 - but i wouldnt run that on twitch as non-partner

Btw, you can remove the "deblock=1:1" from the commandline, as "tune=animation" allready sets it to that by default
"direct=spartial" should be "direct=spatial"
If I may add, "aq-strength=1.3" can help with blockyness, and can probably help you reduce bitrate about 500kbps without much more load on the CPU

level=4.1 no-cabac=1 ref=2 bframes=0 direct=spartial deblock=-3:-1 me=dia no-mbtree=1 subme=3 sync-lookahead=0 rc-lookahead=0 trellis=0 weightp=1 qpmax=38 qpmin=15 threads=2

@Zidakuh
you are wrong about "tune" reseting x264 options - those custom options overwrite all presets etc;
but i will try "aq-strength=1.3" today
