Tip: to capture system audio, tick "Share tab audio / system audio" in the browser popup. On macOS, sharing system audio usually only works when sharing a Chrome tab.
Screen Recorder Guide

🎙️About audio recording
- System audio: tick "share audio" in the popup; support varies by browser/OS
- Microphone: you will be asked for permission the first time; mixed in for narration
- System audio and microphone can be on together and are mixed into a single track
💡Tips
- Exports WebM (VP9+Opus) by default; optional MP4 conversion loads a large resource on first use
- With camera PiP on, drag it in the preview and use +/− to resize
- Clicking the browser "Stop sharing" prompt also ends recording on this page
