On Film Editing, Edward Dmytryk

Rule 1. Never make a cut without a positive reason.
Rule 2. When undecided about the exact frame to cut on, cut long rather than short (Dmytryk, 23).
Rule 3: Whenever possible cut 'in movement'" (Dmytryk, 27).
Rule 4: The 'fresh' is preferable to the 'stale'" (Dmytryk, 37).
Rule 5: All scenes should begin and end with continuing action" (Dmytryk, 38).
Rule 6: Cut for proper values rather than proper 'matches'" (Dmytryk, 44).
Rule 7: Substance first—then form" (Dmytryk, 145).
