Background of a Project
Two parameters in a project’s Properties Inspector affect the background color of a project
and how a composition appears when exported out of Motion. (To open a project’s
Properties Inspector, choose Edit > Project Properties).
Use this color well to set the color appearing in the Canvas when no
other object obscures the background.
Note: To export a project with a premultiplied alpha channel, Motion always renders
Use this pop-up menu to set whether the background color is rendered as
part of the alpha channel. If set to Solid, the background color creates a solid alpha
channel. If set to Transparent, the background color does not render as part of the alpha
channel. In either case, the background color is visible in the Canvas.
