Live Video Feeds
A live video feed can be can be applied through either DVE, Texture or Hybrid mode. If alpha is required for the external video, open Config and enable alpha in Video Input (see the Configuring Viz section of the Viz Engine Administrator Guide).
-
Specifically for Matrox cards: Enable w/Alpha when you require external video with alpha. The Matrox board combines two of the video inputs in pairs, to serve both fill and key. Inputs A and B, and input C and D are combined, respectively.
-
Use the Stream media asset to capture input using the Matrox X.mio 3 IP card.
Tip: When hovering the mouse pointer over a Live Video Feed asset, the tool-tip displays the resolution configured for that Live Video Feed.
