QLab is a multimedia playback cue-based software designed for theatre and live entertainment. It runs on Apple OS X, we have a Mac Mini for this purpose. It's main domain is in sound, but the video aspects of the software have grown greatly in version 3.
The best way to learn QLab is to play around with it. If you have an apple computer, download a copy from http://figure53.com/qlab/, do bear in mind that the free version is more limited that the one avalible in the theatre.
A load of fantastic videos explaning each feature can be found here: http://figure53.com/qlab/documentation/
Training will be run throughout the year for those interested, please contact the Technical Director if you are.
