The software is Plotagon, which is free and in beta. It was shared with me by Tom Hodgers, a member of the POT Cert class, because I was looking for a replacement for the now defunct Xtranormal. I ran it on Mac OS 10.6 even though it requires 10.7. Then I uploaded to Vimeo, until I realized they (still) don’t have captions. So I uploaded to YouTube, put in the script for the new transcribing service, and then used a special embed code (cc_load_policy=1) to force the captions to show.
I liked it enough to make it my own Video Assignment (#1225).
