In the Studio, if you or a participant have a video frame that appears black or blank, first try refreshing the Studio page or selecting a different camera. If those steps do not resolve the video error, your browser's Hardware Acceleration setting might be causing it. Follow the steps below to change whether Hardware Acceleration is on or off.
