Darn, I can't come up with a context in which I would cite the fantastic video below. There are more authoritative sources for the chemical facts it contains, and I know nothing about animation to refer to the techniques or effects Christopher Hendryx (2009) uses.
Well that should do I guess to get to the point, which was to give an example of citing Vimeo in APA Style, which would appear in my reference list as:
Hendryx, C. (2009). Oxygen [video]. Retrieved May 7, 2009 from http://vimeo.com/4433312
Unless of course one wanted to cite an aspect of the video that was contributed by someone else... for that video, perhaps some aspect of the narration (very appealing, I'd listen to Andrew Bailes (2009) again :D )... In that case:
Bailes, A. (Narrator). (2009). Oxygen [video]. Retrieved May 7, 2009 from http://vimeo.com/4433312
(or see a different example, citing an interviewee, below the video)
What makes it fantastic to me is the FUN presentation of basic information about Oxygen (and its interaction with Iron, Barium and Helium), perfect for an educational setting. I'd love to see a whole series of similar videos presenting the qualities of other elements (as would other viewers, like Steven White, {sad that I could not link directly to any of the comments at Vimeo}).
Oxygen from Christopher Hendryx on Vimeo.
I wonder will anyone read this far?
Okay, say we have a video that contains a few interviews, and we are citing only one of the interviewees? Perhaps David Rosenthal's (2009) points about his Doctors 2.0 endeavour within the video The Next Generation of Doctors. I would do this:
Rosenthal, D. (Interviewee) (2009). The Next Generation of Doctors. [Video] Retrieved August 21, 2009, from http://vimeo.com/5379566
Please tell me which video you're planning to cite in your paper?
