I leave the replay buffer on in between recording scenes. I use a Scene Collection that leaves my webcam off by default, and only switch to a Scene Collection with a webcam source when I actually intend to record something that needs the webcam. If you switch to a Scene Collection with no sources using your webcam, then your webcam will turn off. If you have any sources in a Scene Collection that use your webcam, then your webcam will stay on even when it isn’t being used. I like to fiddle around with new ideas in a Scene Collection I’ve named “Playground”. Making new Scene Collections gives you a space to play around with new ideas for scenes and keyboard shortcuts, without disrupting the main setup(s) that you’ve put together. I only have one Profile, which I’ve named “Default” (rather than the default of “Untitled”). You can create multiple Profiles and Scene Collections in OBS. Namespaces for Scenes + Turning Off the Camera In the Audio Mixer panel choose Gear Settings > Advanced Audio Properties then set Audio Monitoring to “Monitor and Output”. When using a Media Source, here’s out to turn on the audio. However, it wasn’t obvious to me how to get media sources to play their audio. “Media Source” video sources are essential when showing prerecorded video, or using a replay buffer. Here are a handful of things I’ve found useful, that perhaps weren’t immediately obvious to me, from my early experiences with OBS. As a newcomer to OBS, I’ve been regularly discovering new features that make my OBS experience better.
