Question / Help x264 keys syntax

Hello, tell me about x264 keys syntax for OBS plz. I have question about how to write correctly. For example - (b_adapt=2 or b-adapt=2 ; aq-mode=1 or aq_mode=1 etc...) thank you in advance.

All parameters that set by the used preset should be overridden by the x264-params=
Here is table of encoding parameters that is set for each preset:
http://dev.beandog.org/x264_preset_reference.html

So, if you whant to modify some, try to add x264-params=b-adapt=2:rc-lookahead=60 and so on (this example overrides two parameters from the slow preset that is in use on your screenshot).

Сложна.... так какой синтаксис съест ОБСка? по ссылке с таблицей там таже хрень rc-lookahead=60 и в этой же таблице чуть ниже тот же ключ уже с педалью...rc_lookahead=60

 

[blitzgame]

Мне похоже проще через slower с ключами ref=5 me=hex subme=8 и все .. Нет ключей с дефисами и педалями

 

[blitzgame]

Slower ref=5 me=hex 1920 на 1080 60 ФПС 7500 CBR битрейт... вывозит ryzen9 3900x (твич ест такой поток)

If you didn't see the difference - then leave it as is.

About the options.
x264 encoder uses special key x264-params= and special syntax for this key that includes colon : symbol as separator to override the parameters in the used profile.
