Bars aren't required, nor is a slate or excessive amounts of black. (They would get lopped off any entry that had them upon being imported into our system anyway.) We just wanted to give some examples where the total amount of time consumed on a tape (in particular) could be longer than 5 minutes. However, the body of the video MUST be 5 minutes or less once the program begins.
Most of the entries we've been getting this year are on DVD-Video, all of which seem to get right into the program, though I have done some cut-edits on a few with excessive amounts of black. More on that later (in the blog).
