Most of this video is an actual I Love Lucy episode, but it’s bracketed by behind-the-scenes footage of Desi Arnaz introducing the show’s cast and explaining a bit about how the recording works–with the audience filing in and out. However, the video does provide an illuminating look at how three-camera film shooting worked in 1953.

EDIT (3/25/2016): Unfortunately, the powers-that-be at YouTube have pulled this video.
