For NDI, you are only making one connection and the receiving software processes the data and knows what to display. With an alpha key, you are providing a key and fill signal to your switcher.

The difference with those types of keys and an alpha key is that they generally use a single video input and just remove a color. A true luminance key is usually only available on high-end switchers. You can do a chroma key with any solid color. Most switchers can also remove black and will call it a luminance (or luma) key, but it's actually just a chroma key, but using black instead of green. If you're familiar with seeing green screens get replaced with content, then you understand the concept of chroma keying. The other two methods are chroma keying and luminance keying.

SDI using the Blackmagic DeckLink Duo 2Īn alpha key is one of three standard keying methods.

If you want to skip ahead in the article, click on the link below to the section you want to read about. Please refer to this article to see which devices support Alpha Key. This article will outline each output option. These settings (if necessary) are outlined in their own section. Some SDI devices have special settings that are needed to properly work with the Alpha Key option here. One of these features is the ability to send an Alpha Key output over SDI (with suitable output hardware) or NDI. We have integrated most of the modules as core features.

With the release of ProPresenter 7, we no longer have add-on modules that cost extra.
