In videography and broadcasting, Clean Output (most commonly referred to as Clean HDMI Output or Clean Feed) is a raw video or audio signal sent from a device that does not contain any on-screen overlays, user interface (UI) elements, or data indicators. Clean Output vs. Dirty Output
Clean Output: Transmits only the pure video footage captured by the camera sensor.
Dirty Output: Bakes internal camera graphics and UI elements directly into the video feed, which cannot be removed later. Distractions Removed by Clean HDMI
When you enable clean output, the camera removes all of the following user interface indicators from the external signal: Battery percentage and power status Recording status (e.g., the flashing red “REC” icon) Exposure settings (ISO, shutter speed, aperture) Remaining recording time or storage limits Autofocus tracking boxes or grids Why Clean Output Matters
Live Streaming: Essential for platforms like StreamYard or OBS Studio. It ensures that your audience views a professional, uninhibited broadcast without camera menus blocking the screen.
External Recording: Filmmakers often route their camera’s HDMI feed to external monitors/recorders like the Atomos Ninja. A clean feed allows these devices to capture maximum video quality (often at higher bitrates or color depths like 10-bit 4:2:2) without baking settings into the final file.
Video Conferencing: When using a DSLR or mirrorless camera as a high-end webcam via a capture card (such as an Elgato Cam Link), clean output keeps your Zoom or Teams video completely pristine. Other Contexts: Audio and Production Reddit·r/obs
