Virtual Inputs


Virtual Input buttons sit on TriCaster’s Switcher rows just like other video inputs, but in fact they possess very powerful features. Much like the M/E (Mix/Effect) rows of a traditional video switcher, they permit a multi-layer composition to be prepared from multiple sources. In addition to the two sources just considered (Inputs A and B), Virtual Inputs provide an integrated Overlay channel, as well.


Virtual Inputs support two primary video sources. These two sources are labeled Input A and B. Selection is made using buttons in the lower part of the tabbed panel, corresponding to TriCaster’s Switcher sources. When a Virtual Input is displayed, Input A appears above (or, if you prefer, ‘in front of’) Input B by default. If Input A is fully opaque it completely hides Input B. However, when LiveMatte settings for Input A result in transparency, or the Input A source has transparency by virtue of being a 32bit file, or its active Position settings mean it does not completely cover Input B, then Input B will appear through transparent regions in the result.

Position controls for both Input A and Input B appear at right of their respective rows (see above image). Click the double-headed arrow button to open the Positioner. The panel that opens is identical to the DSK layer Positioner discussed in the User Guide Chapter 3.4.2.
