![]() Audio Mixer: provides a VU meter to watch for audio clipping, input volume control and advanced audio filter.Sources: we will set up audio, desktop and webcam capture using this section.If there isn’t one already, create it by clicking the «+» button. Scenes: we will only use a single scene.It can be disabled if you have performance issues during recording (right-click on it).īelow the preview area are 5 dockable sections: The main area will preview the actual output of the recording. Once you have plugged your microphone and installed OBS Studio, launch it and you should find yourself in front of the window below: Of course, you need to download and install OBS Studio. This helps prevent the use of black bars around your recording area, as you will later scale your desktop to the recording canvas. Even if your laptop display looks slightly stretched by the altered resolution, the recording will have the correct ratio. Some laptops have a 1920x1200 native display, which is a 16/10 ratio. Preferably, you should have your desktop resolution set to a 16/9 aspect ratio and not 16/10 or 5/4.Optionally, you may also be able to forward your mobile phone audio input over bluetooth or using some dedicated app, which will generally provide better ambiant noise cancellation.A dedicated microphone, possibly from mobile headphones, will generally provide better audio quality than your laptop’s integrated microphone.The settings below will most likely lead to a 1.4 GB recording for a 30-minute talk. No GPU is required, as we advise against hardware encoders (Nvidia NVENC, Apple VT H264, Intel QSV, AMD AMF). A 4th-generation Intel i5 at 2 Ghz (2013/2014) will perform decently. CPU-wise, a moderately-recent one will be enough. ![]() Talk guidelines and tips are provided at the end. Optional: adjust audio capture for noise filtering.Configure canvas / output resolution and framerate, video and audio encoding settings.This tutorial will make you go through 5 major steps, which should take about 5 minutes to complete: Lightning talks which do not follow these guidelines (especially output resolution, format and bitrate), will be discarded as processing those will require far more time than their length. Please match these guidelines to the best you can, as the settings below allow us to further process your recordings without losing quality with later stitching and re-encoding. This post provides step-by-step instructions to paper authors, lightning talk speakers and guests to properly set up desktop and audio capture using OBS Studio, an open-source recording and streaming solution available on Linux, macOS and Windows.
