FAQ
Why can't macOS capture system audio?
macOS CoreAudio does not expose system audio capture to browsers — a system limitation. Use a microphone or native tools like OBS.
Is the output MP4 or WebM?
You can choose in the "Video Format" dropdown. Chrome/Edge usually support both; Safari mainly supports MP4. WebM is smaller and higher quality; MP4 has wider compatibility.
Can I record a specific window?
Yes. After clicking "Start Recording", the browser prompts you to choose entire screen, application window, or browser tab.
Is there a recording length limit?
Theoretically no, but browser memory grows with duration; recommend keeping single sessions under 1 hour.
Why can't I get 240 FPS?
Actual FPS is limited by display refresh rate (typically 60/120/144 Hz) and capture source. Even if the slider is set to 240, output may only be 30/60. Stick to 60 or 120 based on your display.
