Well for editors just starting, I think it best they focus on the art of editing as oppoosed to the frustrating pitfalls. When I edited that part(lady drops mask face down,next shot it is face up) I was highly annoyed at the lack of professionalism. Anywho..you do pose a valid point. Funny thing is noone else noticed it in my class but me. Don’t know if you could still buy that footage. (I only edited it last fall) I think my professor (John Marsh) has only been teaching there for 10 years or so.
