Question / Help Best settings for streaming AND recording w/OBS multiplatform

[guillaumemq]

Hi everyone,

Im sorry for my poor english, i am able to communicate but this is not my first language :) !

I am currently using OBS for streaming or recording. Everything is fine and work wonderful in 1080P/60FPS, but now i wanna stream and record at the same time. I've heard you can do it only with the multiplatform version. Actually i am not able to record or stream with multiplatform withouth having issue with my cpu high encoding, i know it's not the strongest cpu but im pretty sure the problem is my settings. I would like to record and stream in 1080P/ 60 FPS if my system can handle it, if not i'll do 720P/60FPS or 1080P/30FPS. Im running two screen at one time, one displaying my game and the other one OBS and chrome.

Here my PC :

CPU : Intel I5-4460
GPU : MSI R9 380 4GB
MOBO : ASROCK H97 ANNIVERSARY
RAM : HYPERX FURY 8GB
PSU : EVGA 80+ 650W
SSD : SAMSUNG 120GB
HDD : WD BLUE 1TB
WINDOWS 10 HOME

Thanks a lot for the time you'll take to help me, i appreciate it a lot :)

Personally. if you have to record at 1080@60 locally, I would us OBS studios and for the local recording, set 1080@60 using VCE at a higher bitrate (cannot use buffer 0 trick with h264 encoders).
Then for your local recording instance. 540@60fps 2000 bitrate using x264.

I have a friend that does 720@60 and 1080@60 VCE but still has some issues and he has an 4790K. he often sets streaming down to 616p or 540p to keep his 60fps.

Note that in OBS Studios, the downscaling is done in the output tab under streaming. The video tab will be set to no downscale.

Hi Dping, You suggest using two programs ? OBS and studios at the same time ? You said two time for your local recording one at 1080 and one at 540 .... im pretty lost rigth now !

No, OBS studio by itself. it can do both. local recording with VCE (h264 hardware encoder) and streaming with x264 software encoder.

fps needs to be the same, scene needs to be the same but output resolution and bitrate can be different.

Ok I understand. Actually I can stream at 1080P/60fps but while recording you suggest I downscale to 540p ? And for the VCE do you suggest any other setting I should modify

both encoders will need to be tweaked for the game you capture. some games will use more CPU threads, some will be more GPU dependent encoding on both means that you might have to make sacrifices on one or both encodes.

the 540p60fps ensures that there is plenty of room for all games. any higher and expect some issues since you only have an i5 (4 threads) to share between the game and the x264 encoder.

the best all around thing to sacrifice would be to reduce fps to 48 on both encodes if you experience issues.
