If two screens overlap by more than 90%, they will be treated as double-stacked, and QLab will send the same image to both screens.QLab automatically detects when edge blending should happen and feathers the edges of each screen as appropriate, according to the following rules: Each surface may have more than one screen assigned, and each screen may be assigned to more than one surface.
Once a surface is defined, one or more screens can be assigned to it. Each Video, Camera, or Titles cue you create is then assigned to a surface, and any geometry adjustments you make are relative to that physical surface. Or you may have four projectors edge blended on a scrim, in which case you will have just one surface (“Scrim”). For example, you may be projecting onto two walls and a door, all at different angles and all covered by one projector, in which case you will have three surfaces defined in your workspace (“Wall SL”, “Wall SR”, “Door”). Basic structureĪs a rule, each surface in a QLab workspace corresponds conceptually to a physical surface on the stage. * Multiple single-screen surfaces can be created without a license, but only the default surface can be used to play cues. The various advanced features introduced by QLab’s surface setup require different licenses, as follows: Feature

The free version of QLab allows you to work with the simple case of outputting video to a single screen that you choose as a default surface for the workspace.
As such, there’s a lot of potential for complexity the concept of surfaces allows that complexity to be isolated from the process of cue programming. Surfaces are designed to accommodate an extremely wide range of workflows and setups, from single screens, to video walls, to multi-projector blends on curved surfaces. By creating QLab surfaces which represent the physical surfaces onto which you’re projecting, QLab allows you to focus on the contents of your design rather than the mechanical details of your projection system. A surface in QLab is a virtual video output which has one or more actual video output devices assigned to it. QLab uses an abstraction called Surfaces to output video.
