How do I cite a video or DVD?
You need the following information (if it exists): Producer(s), Director, Year, Title of the picture, Medium (VHS, DVD, Motion picture, etc.), Location, Studio.
In the first example, the Studio is the same as the Producer. Much like a book that has the same author and publisher (e.g., National Institutes of Health), use the name as the author, and where the publisher information goes in the citation, simply put the word Author.
The third example is of a movie seen in the movie theater, rather than on a DVD or VHS or other format.
