> <i>Because it uses face rec, you can ONLY show your face, and if you disappear from view your audio will stop after a while, to avoid situations like when you need to go the the restroom but forget to mute.</i><p>Of course, the <i>real</i> killer app for Zoom calls is the opposite of this: some kind of deep fakery that makes it seem we're there when we're not.<p>Yet as it is, this is a fantastic idea. It's surprising video codecs deal so little with the nature of the images (AFAIK) and try to be generalists.<p>As this demonstrates, not all pixels are created equal.
