The description of QLab - Play With New Friends
QLab is an audio, video and lighting control program, mainly used by theater and other companies in charge of artistic events or performances. This tool is versatile enough that both users who have to manage a small event for a handful of people, and large companies, which host events will hundreds or thousands of attendees, will find useful.
You can control all aspects of the show from QLab's main screen. There is a timeline bar for easily working with audio by making audio production automatic or by manually changing it whenever it suits you. You can even combine both methods, with some audio programmed and others that you can play manually, with just one click.
Lighting control is equally as simple. There is a series of default libraries that you can work with immediately, but you can also customize your own if you want. Controlling the lighting is as flexible and easy as controlling the show's video and audio, although, of course, it will also depend greatly on the equipment you're working with.
QLab is one of the most widely used show tools in the world and for good reason: it has everything you need to make sure the show never stops.
