Builder Hub: Set up Multi-Camera

Multi-camera setup lets you add your camera angles, then cut between them on one low-latency pipeline. Viewers watch one continuous video while you decide which camera is on air.

The page has two sides:

  • Set up your cameras works on your own streams. It needs an account.
  • See it with sample cameras plays four camera angles we stream for this demo. Anyone can open it, guests included.
Open it

In the Builder Hub menu, open Build › Stream › Set up multi-camera.

Set up your cameras​

The page opens the Multi-Camera Switch tool. You're already signed in with your Builder Hub account, so it opens ready to use. Learn how it works at the top sums up what you can do: pick your own streams as camera angles, group them into one room, and switch between them live, with a log of every switch.

The tool walks through four steps:

  1. Connect. Your Builder Hub sign-in carries over, so this step is already done.

  2. Camera Angles. Choose How many camera angles? Then:

    • Create new makes a fresh stream for each angle.
    • Use existing lets you pick streams your organisation already has. Refresh streams reloads the list.

    Then click Configure Streams.

  3. Stream Group (Room). Bind the angles into one group. Enter a Group Name, or leave it blank to get one generated, and click Create Stream Group. Reuse a name to pick up a group you made earlier: its angles are replaced, and whatever it has on air stays on air.

  4. Control. The player shows what viewers see. Click a camera, or press 1 to 6, to cut. The Event log lists every switch.

Your own angles, grouped and switched live.

In Control, Copy player link gives you the link to the player for your viewers, and How it works & API shows the ingest details and the exact API calls for your group.

For every step of the tool in detail, see Try it in the demo in the Multi-Camera Switching docs.
