Screen Direction

 A character should should enter the opposite side the character exited in the last corresponding clip. For example if the character is seen walking into fame from the left to right, the next edit should show the same thing to tell the viewer that the character is moving towards their goal. If this rule is it followed it will appear to the viewer as if the character on screen is moving in different directions spontaneously. The same rule applies to diagonal perspectives. The character should be moving in the same direction.
