Here at Restream, we have very loose guidelines on our incoming streaming settings, as we don't display your streams to an audience. Instead, we send it off to your end platforms such as Twitch, YouTube, Twitter, Facebook, and more. 

With that in mind, it's important to make sure you follow the guidelines set by each platform you intend to stream to with Restream. To get a quick overview of what these guidelines are, check out our Platform Setup section!

Restream Common Guidelines

While we have no set limitations, we find these settings are what most Restreamers are using.
