I'll bite. I've used After Effects at the grab-a-demo-copy level for motion tracking and stabilization and rotoscoping. I don't remember anything that would have allowed me to detect and amplify color changes in someone's face that way, or amplify movement of a given period like the shots of someone's pulse or of a baby breathing -- especially not with a general-purpose temporal amplification filter instead of really specific code. I'd love to know how to do that stuff with After Effects, though. Can you be a little more specific? My guess is you might end up with something along the lines of, say, take a specific clip of a guy's face, mask the face, average the color, detect the subtle changes with a script, and use the output of the script to control a color filter. Likewise if I had an existing clip of a particular sleeping baby, I could target the chest, motion track, and feed the tracking data into a filter. But that's a laborious way to fake particular outputs of what this software does in realtime on arbitrary clips of things moving or changing -- it's not nearly equivalent.
