Hey, i am looking for help in successfully running 2 OBS studios on 1 system.
i found an old guide from 2014 for OBS classic, but being 2017 i would like some fresh input based on today's version.

Scenario: I would like to run 2 OBS studios together on 1 PC, both sending separate streams to the same youtube channel.
2 stream keys 1 channel - i already have the 2 stream keys.

Stream 1 is already running smooth and fine and has been for the last 6 months using OBS studio, now i am looking to get a 2nd stream running too but using the same PC.

Stream 1 is a 24/7 stream and i do not want to do anything that will cause this to end, so i want some pro advice on getting this setup smoothly if possible.

Do i have to install a 2nd OBS to a separate location on my system, or can it be done with a single install of studio?
I do not want to overwrite the current settings or risk wiping my current scenes etc on the existing stream that is already running.

They will both be running different streams so, i need to set this up so the 2nd instance of OBS is safe to create new scenes and not have any settings screw up on first instance.

i hope i am making sense here.

Any help is greatly appreciated, and thanks in advance.

Well for me at least i can simply open 2 instances od OBS studio... though you can go into properties of your obs shortcut and add a -multi behind "C:\Program Files (x86)\obs-studio\bin\32bit\obs32.exe" (or whatever your path may be) same counts for the 64bit

--> "C:\Program Files (x86)\obs-studio\bin\32bit\obs32.exe" -multi
--> "C:\Program Files (x86)\obs-studio\bin\64bit\obs64.exe" -multi

Hey, @alpinlol that is basically what i saw for the OBS classic guide from 2014, people saying add a -multi
but my question to that would be IF i done a reboot for updates etc, upon restart what would happen to the settings if each had different setups before the reboot (keys output etc).

@Suslik V, never heard of OBS portable mode, i will investigate.
The System i use now runs OBS studio for 1 stream, and i also use an elgato HD 60 pro for a separate game stream to a different channel, both streams run flawlessly at same time. OBS using around 15% cpu and elgato 10-15% (no frame drops) both streaming at 720p.

Thanks for your input guys.

OBS Studio can be launched as many times as you want without needing any special flags, but by default it will use the settings stored in %appdata%.

Make a copy of the program directory itself and set the --portable launch param which will then store the settings in the program directory itself.
