Once these cues are running, the imagery that they produce is all treated the same way by QLab. Text cues render styled text as still images.

Camera cues play live video from webcams, Blackmagic Design video capture interfaces, and other programs on your Mac via Syphon. Video cues in QLab play back pre-recorded video or still image files on your computer. In all cases, once the surfaces are set up, you can stop thinking about projectors and simply assign your Video cues to their intended surface. In that case you could create just one surface (“Scrim”). Or you may have four projectors edge blended on a scrim, which you wish to use as one big projection area. 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 could create three surfaces defined in your workspace (“Stage Left Wall”, “Stage Right Wall”, “Door”). The idea is that each surface in a QLab workspace corresponds conceptually to a physical projection space on the stage. By creating QLab surfaces which represent the physical surfaces on which you’re displaying video (using projectors, monitors, LED walls, or anything else), QLab allows you to focus on the content of your design rather than the mechanical details of your projection system. In QLab, a surface is a sort of virtual video output which has one or more actual video screens assigned to it. QLab uses a concept called Surfaces to output video. The words “screen” and “display” are more or less interchangeable. “Screen” means any physical device that displays the contents of Video cues. No matter whether the imagery is moving or still, digital or analogue, displayed via a projector, a TV, an LED wall, or a projection-enabled intelligent light, it’s all grouped together under the name “projection design.” In QLab, a Video cue is the type of cue that deals with projection.

QLAB SHOW PROFESSIONAL
A note on styleįollowing the nomenclature of professional theater in the US, “projection” is taken to mean any form of video or film as used in a live performance. The video workflow is intended to allow you to set up your workspace, configure your hardware, and then basically forget about it and just focus on your projection design. Video in QLab is designed to be flexible and adaptable.
