I was playing around with the optical flow patch (part of Flowkit), and stumbled into this kind of color offset effect seen in VHS playback. It’s a five minute effect! Try it out.

Of course, it was an online conference, but at least it was nice seeing familiar names in the live chat window; Noland Chaliha, Clay Weishaar, Ben Knutson, Sarah Mayer, and Luke Hurd, to name a few.
