TinyDesk.video

TinyDesk.video turns one to five portrait photos into a short desk-concert video. The casting page puts role slots next to a reference clip, so you can see who will sing, play sax or keys, or join the backing vocals before generating. You can keep the remaining reference performers for a solo clip, or cast a whole group. The result is a roughly 15-second MP4 with sound. The site has a public five-person example so you can see the finished format before making your own.
