Markers for a successful livestream

In this set, you can see markers placed on the floor with the help of tape. These are just as helpful for the protagonists as they are for camera control and direction. This is because the markings are intended to prevent the presenter, who is in the frame, from getting too close to the cameras or running out of frame. In this case, the PTZ cameras could pan along, but the shooting area is limited by the background, as is the area of illumination.
