Live Action Replay allows you to use your iPad as an instant replay field monitor companion app to an HDMI output capable camera. Using a UVC capture USB-C input device, you can record HDMI input video, and then replay and review that capture while simultaneously capturing more video. This app does not use the internal camera of the iPad. App requires a UVC-USB camera or HDMI input. Not compatible with Nintendo switch without an HDMI capture device. No audio is captured from the input.
