This is a clip of red/cyan 3D glasses rotating center frame and then moving toward the camera to break the scene. It functions as a transition and it can be used to introduce titles or switch into stereoscopic content. The download includes one clip rendered with motion blur, and one without. The clips are rendered as Quicktime MOVs Animation codec with alpha.
If you would like to animate your own, you can purchase my 3D model of the same glasses located here:
