Three Ways To Create A Vertical Multistream - Stream On Instagram Live, TikTok and YouTube Shorts!

Instagram recently released its stream keys to more people so let's set up a vertical multistream with three different methods.

Stream Keys

Below is how to find your stream key on each platform.

  1. Instagram - Switch to a professional account then on a desktop PC click on "Create" and choose "Live video". Choose a title and choose "public" and your stream key will appear.

  2. TikTok LIVE - Join a free TikTok LIVE agency to get a stream key then obtain it from the LIVE Center.

  3. YouTube - Hit create and press go live. Apart from the Aitum Vertical method, you don't need the stream key.

  7. Then start the stream on the YoloCast website.
