Are you frustrated because OBS doesn’t natively support streaming to multiple platforms at the same time? By installing this plugin, you can stream to multiple platforms simultaneously with ease!

Recommended settings for streaming to Twitch and YouTube together
Many streamers choose to broadcast on both Twitch and YouTube. I recommend using Twitch’s settings as the base—set your bitrate to 6000 kbps. Handling a separate 4K high-bitrate YouTube stream requires a powerful GPU. YouTube supports up to 50 Mbps for 4K 60 FPS, while Twitch only supports 6 Mbps for 1080p 30 FPS.
So it's better to keep Twitch’s native settings and let YouTube follow the same stream.
(If your GPU is strong enough or your game isn't very GPU-heavy, you can try sending a dedicated 4K stream to YouTube. My 4070 Super can’t handle it.)
I also recommend reusing the same encoder across platforms to reduce system load.
Important Notes
Be mindful of your upload bandwidth. If you stream to multiple platforms—such as Facebook, Twitch, YouTube, and TikTok—your upload usage can easily exceed 100 Mbps.
Avoid increasing bitrate blindly; it may cause stuttering or loss of visual detail.
The more platforms you stream to, the heavier the load on your system, so make sure your hardware can handle it!
