Scenes are one of the most fundamental features of Composer. A project may consist of one, two, or multiple Scenes. In a multicamera setup, a project usually consists of the same number of scenes as the number of cameras or more.

A scene usually consists of several layers of inputs.  Inputs used in a scene are stacked into several Scene layers - each representing one input or a Scene.

For each of these Scene layers, Operators (effects)can be applied.

For the selected scene, the preview window will display the scene's output (assuming the preview function is activated).

Working with Scenes

To add a scene, use the Add Scene button:

Scenes will be listed in the details view under the Inputs & Scenes tab.

To change the display name of a scene, double-click on the name found next to the yellow arrow.

Use the yellow up/down arrow to collapse/expand a scene.

Right-click on the input to access actions.

Copy image will copy the selected scene to the clipboard.

To duplicate a scene and all its scene layers, operators and targets, select the Scene input (in this example "Program Out Scene") and right-click, in the dropdown menu, select "Duplicate Scene" to make a copy of the scene. Remember that some operators or targets need to be reconfigured with unique settings, for example, the RTMP target. 

To delete a scene, select the top row of the scene and press the DELETE KEY or right-click and select "Delete".

Scene Properties

Scenes have the following properties:

• Description - optional free text description.
• Width - Scene width in pixels. Default value 1280 (can be configured in Settings). Max value 4096.
• Height - Scene weight in pixels. Default value 720 (can be configured in Settings). Max value 4096.
• Background colors and alpha (group) - RGB and Alpha values used when initializing the scene.
• Processing information: read-only. Color space converter used by the scene.

Scene outputs

Scene output consists of RGB+Alpha and a 4-track of stereo audio. The scene output can be used either by Targets attached to the scene or in other scenes (creating nested scenes).
