  Does anyone know how to cleanly delete dental braces off teeth?

  Thanks,
  Tyler

  I believe a dentist has to do it.

  You have to do it by hand, possibly by replacing the set of brace-teeth with a picture of a set of no-brace teeth. Depending on the size of the teeth in frame, and the amount of subject movement, it could be difficult to impossible.

  I suggest replacing the entire mouth with new teeth, since trying to paint individual teeth would be nuts.

  If the mouth stays open, you might be able to use the motion tracker to track the mouth then apply the new teeth to the tracker, then mask the teeth where the lips cover them. But it could look really dumb, and jiggle a lot.

  I’d walk away from this one.

  And they have long flowing blonde hair.
  And they’re wearing fatigues.

  We’re not being facetious, it’s just that you can imagine doing this for a still in photoshop. Now imagine doing it for 30 images per second. Now imagine having to eliminate the jitter that comes from doing this kind of frame-by-frame work. Sure, do it for a few frames, then charge by the hour if you still want to do it. If you just have to do a few frames here and there, it might be doable.

  This is hard because you’re not just removing something, you’re replacing it with something else. And that something isn’t smooth and featureless, so your mistakes will be evident. And it’s on a human face, which is usually where your audience is looking.

  If somebody imagines that anything can be done on a computer, they’re right.
  But it might have to be done by hand. Can it be done on time and within budget?

  Now if the person were facing camera directly, and not moving, not talking, just smiling, you might be able to paint out the teeth in one frame, then use that frame to replace the rest of the frames as I mentioned earlier. But if the talent moves or talks, you’re in for a lot of hand work. It’s called rotoscoping, or roto, by the way. Quote hourly, with no ceiling.
