How to Use Multiple HDMI Inputs with Live Preview

Live Now supports a multi-input workflow on compatible devices, allowing external HDMI sources to be previewed without a separate hardware video mixer.

Requirements

  • A compatible iPad and Live Now version that supports multiple external inputs
  • Two supported UVC HDMI capture devices
  • Cameras, cables and sufficient USB bandwidth/power

Step-by-step guide

  1. Connect each camera to its own HDMI capture input.
  2. Attach both capture devices to the iPad using a compatible USB-C hub or connection arrangement.
  3. Open the camera input controls in Live Now.
  4. Identify each external input and check both previews.
  5. Select the intended source for the live output and verify it before streaming.

Important notes

  • USB hub bandwidth and power requirements are important for two video inputs.
  • Available preview and switching controls depend on the app version and connected devices.
