Draw video content in front of a camera's Scene.
Scene content is visible through any transparent areas of the video content.
The Camera clipping planes determine where video content is rendered. Video content is offset by a factor of 0.00005. To render Scene content on top of the video, you have to position it between Camera.nearClipPlane and Camera.nearClipPlane + (Camera.farClipPlane - Camera.nearClipPlane) * 0.00005.
