Could go even further and produce multiple sections and let the "algorithm" edit them together in whatever order.
intro (2x 15 second clips pulled from random places in all the other sections)
section 1 (a/b/c)
section 2 (a/b/c/omit)
section 3 (short/long)
section 4 (a/b/c)
It would be like a choose your own adventure video, without the choosing, or the adventure.
