Each cue is assigned to a surface, and then all the cues playing simultaneously to a each surface are composited and sent to the actual physical displays. 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.

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.

Since relative fades are additive, and the Audio cues are now playing at -10, you’ll end up with very very loud sounds.Video in QLab is designed to be flexible and adaptable. Do be very careful not to accidentally run that Fade cue twice while the Audio cues are playing.Now, when that Fade cue is triggered, the Audio cues within the Group will have 49 dB added to their level, bringing them to -10 as planned.Create a Fade cue targeting the Group cue, and in the Levels tab of the inspector, set the master level of the Fade cue to +49.By default this is -60 so if that has not been changed, set your Audio cues to -59. Once all the Audio cues sound good, bring each of their master levels to 1 db louder than the minimum volume level established in Audio settings.If -10 is too loud or too soft, use the individual cue output levels for each Audio cue to get the right loudness.

For now, let’s agree on -10 for that level. Set the levels of all the Audio cues in that Group such that their master levels are the same.

Create several Audio cues and place them within a Group cue to your taste.What to do? The trick lies in starting your cues just slightly louder than -INF.

This is a problem when your goal is to fade in several sound cues from -INF to some audible level, because -INF plus any amount is still -INF. Because the starting state of each child cue may be different, Fades which target Groups can only be relative fades. When a Fade cue targets a Group cue, QLab attempts to apply the result of that fade to all the child cues within the Group.
