Bitfocus Companion turns a Stream Deck, an X-keys, or any other panel it supports into a show controller for many programs at once. The Visibox connection adds Visibox to that list. Buttons trigger Clips, select Songs, run the transport, set the output level, and drive Real-Time Control, and they light up to show what Visibox is doing.
Visibox's Camera Clip can display any live video feed, not only webcams. USB cameras are the most common input, but you can also feed in any HDMI source (a game console, a secondary computer, a video switcher, a broadcast camera) using an inexpensive HDMI capture adapter. If your computer sees it as a camera, Visibox can use it.
Visibox drives an Elgato Stream Deck through a plugin that runs inside Elgato's Stream Deck software. Drop a Visibox action onto a button and it triggers a Clip, switches Songs, steps through the set, or sets the output volume. Clip buttons carry the Clip's own thumbnail, so the deck reads like the Song in front of you.
