When cutting together two shots of a fast action, say a man chopping wood etc, my usual method is to find a suitable matching frame in both shots and use that as the cutting point. But I've just been reading Michael Rabiger's 1989 book "Directing, Film Techniques and Aesthetics" and he says you should repeat the action on the next shot for 2 or even 3 frames.... "since the eye does not register the first 2 or 3 frames of any new image."
I find this fact rather hard to swallow. I feel as if I've always not needed those extra overlapping frames. But on the other hand maybe I've only found the cut acceptable due to the very fact that I am 'expecting' the subsequent shot and not seeing the film with the fresh eyes of an audience. And it's not exactly an easy one to ask a viewer.
I'd really like to hear what you think. Should the action be repeated to this extent ?
Or does it vary according to the size of screen etc.
