title: Determine consecutive video clips
body: <p>I a long video stream, but unfortunately, it's in the form of 1000 15-second long randomly-named clips.  I'd like to reconstruct the original video based on some measure of "similarity" of two such 15s clips, something answering the question of "the activity in clip 2 seems like an extension of clip 1".  There are small gaps between clips --- a few hundred milliseconds or so each. I can also manually fix up the results if they're sufficiently good, so results needn't be perfect.</p>
