Side view lip flap?

[James Sharp]

What is the best way to handle side view lip flap. The kind where even the chin and jaw are moving.

-Find the parts of the face that are moving and mask them out.
-Place a frame of the mouth/face not moving underneath
-Rinse
-Repeat

Alternatively, either not use that clip or deal with it the way it is. It really depends on the segment and the video. A montage, for instance, isn't always ruined by characters acting natural and doing natural things like interacting through speech.

If you want to do it up right, you take one frame with closed mouth and match it up overtop of the character's mouth in whatever work best for you either by tracking or manually repositioning it to match position (depending on if the character is walking or if there's a slow camaera pan).

Then you mask out the closed-mouth jawline to whatever is appropriate to cover any movement that happens in the check/jawline or neck of the character within what would be their silhouette (pay attention to movement on any jawline shadows from frame to frame).

Then you need to somehow recreate the background directly around the area around the mouth, etc, and put it between the main footage layer and the close-mouth layer. This will hide the open-mouth jawlines from poking out underneith. If the background is complex and/or moving, then you're going to have a lot of fun here.

Simple as that

I think I know just what we need

Anyways, the others have some good suggestions. If there is little to no movement in the scene, which gets in the way of things, you can always freeze the frame where the person's mouth is closed. If the scene looks too static then I guess you could add in some pan/crops, movements, effects or getting multiple things from different scenes/sources etc. and making up your own scenes.

Yes that's true, if the scene really is that simple, then this is all that you'll need to do.
