Seven Rules for Film and Video Editors
Matt Jeppsen | 09/07
Tried-and-true principles to guide you in the edit suite

Edward Dmytryk, film industry legend in the directorial and editorial fields, enumerates seven rules to follow in his text On Film Editing (Focal Press, 1984).
Rule One: Never make a cut without a positive reason.
“The only reason for using another cut is to improve the scene.”
It is unwise to cut film adhering to arbitrary principles, such as keeping all shots under a certain length. While Dmytryk argues that every cut must be made at a precise and perfect point, he gives no indication that these particular edit points are governed by anything other than the drive to improve what the scene intends to communicate to the audience. Some scenes require no editing at all if the composition and camera movement are strong enough to support the intent of the scene. Other scenarios, particularly action and montage sequences, require constant cuts in order to communicate the scene’s intent. If another take does not make emotional truth clearer or capture the action more appropriately than the current take, then by all means do not make a cut.
Rule Two: When undecided about the exact frame to cut on, cut long rather than short.
“Splicing a few frames back onto a scene which has been lopped short makes ‘jumpy’ viewing, and a cut full of such amendments makes proper visualization difficult and perceptive judgment impossible.”
Just the most basic common sense rule there is. When cutting filmstrip, it is much easier to trim a bit of excess duration than to splice more on to increase duration. Dmytryk adds that the first instinctual decision regarding where to make a cut is usually the right one; however, you still may want to cut a little long in case you’re out of touch with your instincts. Note that this rule doesn’t so much apply to nonlinear video editing, unless for some masochistic reason you’ve disabled your undo function.
Rule Three: Whenever possible, cut in movement.
“Creating a ‘diversion’ of sorts ... is also the principle at work in the action cut.”
The concept here is that during movement of any kind, be it a man sitting down on a park bench or a woman darting her eyes to the left, cut in the space between the beginning and end of the action so as to mask the cut. The goal is seamless, invisible, “magical” editing. This is not possible without the greatest command of timing: timing that comes from an understanding of human perception and eye movement. If you choose to cut too early, the following cut will seem nonsensical and inappropriate. If you choose to cut too late, you may deny the audience key information and try their patience by extending the previous shot. There is a precise moment at which to make the cut: near the dead center of the action. For the man sitting down on the bench, you would most likely want to cut at the point of contact between the man and the bench. For the woman darting her eyes to the left, you may want to cut somewhere in the middle of the motion but not before or after. Mastering this fundamental of editorial timing will not only make your cuts seamless but will also strengthen the scene itself in what it intends to communicate. This, after all, is the purpose of editing: communication.
Rule Four: The fresh is preferable to the stale.
“In art, the obvious is a sin.”
In order to maintain the invisibility of technique, a film editor strives to avoid boring, confusing, or disappointing the audience with a poorly managed cut. However, it is possible to jar the viewer from the context of the story with even the most well-intentioned cut. If your shot contains action that exits the frame, do not linger on it even for a couple frames. If you do this and fail to overlap to the next action, the viewer has no new information to feed upon and therefore lapses out of the comfort of the story. Because of only a few frames, your viewer is now examining your set design or lighting. This is exactly what should be avoided. Dmytryk suggests that if frames must be added between shots, do so at the beginning of a fresh, new shot so that the viewer accepts the lingering frames as part of exposition for a new angle or shot.

Yep, all good advice, particularly regarding continuity and emotion. It is something I have tried to explain to people before but it often falls on deaf ears.

Any chance I could get this as a poster with graphics?
I’d like to post it in the office for my editing staff to see.
