A tell-tale sign of a novice editor is the presence of extra frames in every single shot. I bumped into this today when a mentee asked what I thought of his film. The short consisted of cutting back and forth between two characters. Unfortunately, the video didn't "flow" because each moment consisted of a slight pause, the action, another pause and then the cut. Much like this:
As an audience we're left waiting for the next thing to happen and we even know what it has to be. At one point one of the characters runs into a bathroom and shuts the door. We wait while the door fully closes. Then we cut inside and there is a slight pause while the actor gets ready to continue running into the bathroom.
It completely ruins the momentum of the film. What's worse, since this was geared to be a comedy piece, the poor pacing killed every single joke.
I suggested that he try cutting at least a second from the beginning and end of every single shot in his film. Since it was 1:12 seconds long with about 20 cuts, I'm guessing his film could easily get down to a smooth 30 seconds. And it would be much, much better.
Remove Extra Frames
Of course, it's possible to go too far the other way... a topic we will explore tomorrow.
