The general format is as follows:
Author, A. A. [Screen name]. (year, month day). Title of video. [Video file]. Retrieved from http://xxxxx
Sometimes you will not have an author, just a screen name and that’s fine. If that is the case then do not put the screen name in brackets and use that as the author.
Video file you will leave as is. You do not need to say if it’s an MP3 or other media type.
The URL can vary. Double check with your professor if you should use the Blackboard URL or a more accessible link.
