Pretty impressive. The question is, how long does it take to get to the final 2-3 second shot? And how many minutes/hours in post could proper make-up save?
We've done this in CS5. It takes a while but as you can see it can be done, though this example they show is not that over the top retouched, not near any real cosmetic ad or commercial with a heavy media buy.
If you've watched a beauty commercial all are retouched, some more than others. You can almost hear the director in the background telling some star, "don't move too much, don't move too much", because the more you move, the less you can automate in actions in cs5 extended.
Regardless, this is not that much in regards to retouching beauty for commerce, but it does show how well a 4k movie still holds up.
