erhmmmmm..

dropping or blending an orphan frame? why this?

wouldn't it be much cleverer, delaying the video by, lets say up to 3 frames, until frames get dropped or blended? maybe sometime later in the video we have the chance getting some more duped frames that are compensating orphaned frames.

or maybe accept a slight AV async, until a scenechange occurs
(dropping frames directly before/after scenechanges is not noticeable, while dropping frames within a scene IS noticeable)
