What is clean HDMI

Clean HDMI output means that a camera is able to output a live video signal through HDMI without any graphics, marks, data, autofocus regions or any other thing that usually shows on the camera display.

The clean HDMI output only includes just the video, nothing more, so it can then be sent without any visual distractions to any other live video equipment (HDMI capture card, professional video switcher) for live video streaming or broadcasting.
