QLab is a reliable and flexible way to design and run your projections. Play full screen videos and images, or customize the geometry for projection mapping. QLab offers up to 1,000 video layers, chained video effects, per-cue blend modes, text cues, NDI and Syphon for video input and output, and more. We rewrote our video engine from scratch for QLab 5, utilizing Apple’s new Metal framework and vastly increasing the power and flexibility of our video features.

While all of QLab’s pieces are powerful on their own, the true elegance of the program is the way they all work together. There are so many ways to customize your cues: trigger one cue from another, start 18 sound effects at once, loop through a playlist at random, or even set up your cues to start based on the time of day! You can also use timeline mode to adjust the relative start times of your cues with drag and drop. Our integrated Cart mode lets you trigger your cues with the press of a button.

…and more!

Show Control

QLab has extensive support for OSC, MIDI, and timecode protocols for ingoing or outgoing show control. New in QLab 5, QLab syncs to incoming time code. Network cues can send custom OSC, ASCII, and Hex messages over TCP or UDP. These powerful show control tools make QLab an integral part of complicated, multi-department live shows.
