![]() This material is based on a workshop I held with Kevin Glesson with Dublin-based theatre company Dead Centre, which in turn is based directly on our experience of live-streaming 28 performances (as of Feb 2021) of To Be A Machine for Dublin Theatre Festival, Théâtre de Liège and Burgtheater Vienna’s German language version, Die Maschine in Mir. The workshop was supported by The Arts Council of Ireland and Dublin Fringe Festival. We’ll go step-by-step through setting QLab up to work with professional video cameras, and using OBS (Open Broadcaster Software) to stream to YouTube. Then we’ll cover how to add high-quality audio acquision to the setup. Finally we’ll also cover topics like reliability, internet connection and using multiple cameras. This guide is detailed with lots of images and screenshots. This makes it seem long! But hopefully the layout will help you find what you need quickly. QLab is normally used to playback pre-recorded sound and video using a stage-centric cue-based interface, with sound heading out of the computer to a PA system, and video going to projectors, screens, LED walls etc. In order to live-stream a performance, we first need to film it on camera and acquire that live video signal at a reasonably high quality. We also need to capture sound from either the camera mic, or a separate mic e.g. You’ve probably noticed the poor picture quality from cameras that are either part of your computer (your webcam) or that can plug directly into your computer, e.g. They are compact, cheap cameras designed with the reasonable assumption that they’d be used for video calls and the like. Since video chat apps heavily compress video to reduce bandwidth, there’s never been much need for high-quality webcams. □□□ while this guide details how to capture video from an external video camera with a video capture device, you can follow along and test with just your webcam. Then later, if you get your hands on a camera and capture device, you can switch to those and refer back to here then. To do justice to your production, you’ll want to use a professional / ish video camera. #QLAB PRO MULTIPLE VIDEO OUTPUTS PROFESSIONAL#.#QLAB PRO MULTIPLE VIDEO OUTPUTS LICENSE#.#QLAB PRO MULTIPLE VIDEO OUTPUTS HOW TO#.
