To achieve a true linear key, ProPresenter has access to an advanced Alpha Keyer Module. Using this software module in conjunction with a supported BlackMagic Design product (listed below) and broadcast level switchers, ProPresenter can provide perfectly keyed alpha-channel support for graphics, words, and video effects. What's more, Renewed Vision composites the text that is built in ProPresenter, along with the cross dissolves, right with the video background graphics (with or without transparency) for the world's first fully-functional worship-minded CG solution.
Here is a list of supported cards/devices from Blackmagic Designs:
This module can operate in several different modes, including:
If you're running a broadcast switcher, it more than likely that it has the ability to support separate key and fill channel inputs (commonly referred to as Linear Key). Using the Alpha Keyer Module for ProPresenter, you can now send separate key and fill signals to your video switcher.
If you're using a switcher that does not have separate Key/Fill inputs, you can use ProPresenter downstream of your switcher to overlay alpha-keyed graphics and words on top of your video switcher feed. When using this option, all full screen videos will continue to play full screen, and the ProPresenter operator in effect has complete control over what is going to your output device.
The final way you can use the ProPresenter Alpha Keyer Module is to use the software as a Downstream keyer to a video switcher that does not have separate Key/Fill inputs. In this way, you can use a linear or chroma key option with the threshold set to 100%. This option provides a good fail-safe so that if for whatever the ProPresenter computer goes down, you can immediately turn off the key and take the clean program output.
