Do you want to use ProPresenter to stream live video? Do you also want to display song lyrics over your live video? Great news! Once your hardware is in place, it’s easy to do. This tutorial explains how to set up your live video feed with ProPresenter and how to add graphics as an overlay.
ProPresenter supports a live video feed over SDI or USB 3.0. It no longer supports camera inputs that use Firewire. ProPresenter officially supports Blackmagic Design video interfaces, although other devices may work. They can only provide support for Blackmagic Design hardware as that is all they have tested.
Select the input device for your video source. This can be the FaceTime camera, an external camera, or a software “camera” like CamTwist or ManyCams.
Select the audio source (if needed) to be used with your camera.
Preserve Aspect Ratio
This prevents your camera input from being stretched full-screen if your output resolution and the camera resolution don’t match.
Use the Cue Palette
You can use the cue palette to put a video start cue on a slide so that the video will begin automatically on that slide. Similarly, you can use a cue on a slide to stop the video.
