Sharp change of shot's zooming, illumination or coloring of the scene provoke the feeling of space jump.
Two attached shots must be similar in moving direction(if in the first shot a ball is thrown from right toleft, then in the next shot it must break a window in the same direction of flight).
Interlocutors in alternating shots must look at the center from different edges of the screen.
Movie's soundtrack consists of sound (which makes a effect of staying at the place of action), speech, and music (which creates special mood). During the movie levelof the volume must be changed to reach the highest expressiveness.
Soundtrack and scene should be accepted as a whole.
One should avoid long monologues in movie.
If you break a scene, it means that in the next one some particular or interesting event should happen, else this break would look like it is unnecessary and forced.
Multiple breaking of the scene heavily bothers.
Breaking the scene in the most dramatical episode keeps spectators' interest to the going events high.
Simultaneous heeding of more than three plot lines is rather hard.
