Which makes me think: it would be interesting to have a diff tool for videos, but it diffs a representation of the content not specific video frames.
Customers might include all the students of Udacity, Coursera, EdX and Startupschool.

diffIt might work well if you can first pair up the similar sentences from A and B, using word-level edit distance, or mapping to a lower-dimensional space using sentence embedding?
Probably right. I used the term diff as a concept not implementation.
For business talks, you can see it here: http://findlectures.com/?p=1&type1=Conference&talk_type_l2_C...
This includes the older startup school talks, plus a few good software business conferences. For the next phase, I want to highlight talks that are most unique to the category (using word lists in the transcript/captions, not video diff)
