Composite inputs

A Composite is a virtual input built from inputs you already have: add several sources as layers, and the Composite switches as one input, itself, exactly like a camera. The sources it is built from keep working as their own inputs too: a Composite refers to them, rather than taking them over.

Add one

Press Add Input… and choose Composite. It starts empty and transparent, and stays transparent wherever no layer covers it. There is no background colour to set.

Add layers

In the Composite’s own settings, Add Layer lists every other input in your Show; choose one to add it. Layers are ordered back to front, and each has its own Opacity, and buttons to move it toward the front or back, or remove it. A source you add as a layer can stay offline and still be configured here, ready for when it comes up.

Framing a layer

Each layer keeps its own size, position, crop and rotation, set from Size & Position…, the same editor a plain input’s Picture tab uses. Changes to it apply live: if the Composite is already on Program, you will see it move as you drag. A layer does not loop between two framings the way a plain input can: that belongs to an input itself, not to its place inside a Composite.

Showing and hiding a layer during a show

Each layer’s Visible switch shows or hides it at once, on air too. A hotkey or a Stream Deck key, a rule or a Companion button can do the same: Show a Composite layer, Hide a Composite layer, or Show or hide a Composite layer, with the layer chosen by name, such as “Stage · Cam 1” (a source in the Composite twice is numbered by its place, “Stage · 2 · Cam 1”). A key is lit while its layer is visible. Hiding a layer is a cut, and it leaves the layer’s sound as it is: to silence it, use the layer’s speaker switch or mute the source. What you show or hide is saved with the Show.

Next

Framing a source for the full Size & Position editor, and Web pages as inputs, Image and media playlists: both, like any picture input, can be used as one of a Composite’s layers.
