What are the key ingredients in creating a suspense-filled clip?

The first video is private so I couldn't see it.

• In Jaws Spielberg uses the question of "Will he catch the shark or will it get away?"
• He jumps between objective and subjective perspectives.
• He watches the hand movements of characters.
• In Jaws he watches Quinn's hands and feet in his process of preperation.
• In The Colour Purple Celia's hands are shown shaking as she shaves her husband after she's told that if she cuts him he will kill her.
• In Munich the main source of tension is the knowledge that Abner is going to try to kill someone.
• Him meeting his hotel neighbours one of which is the man he is there to kill who turns out to be a friendly person which makes the scene even more uncomfortable.
• Spielberg frames the important objects wisely large and in the foreground. The fishing rod in Jaws, and the razor in The Colour Purple.

• Difference between suspense and shock.
• The audience needs information for the scene to contain any suspense.
• Bomb theory
• Shock is there's a normal conversation then suddenly a bomb goes off which gives about ten seconds of shock.
• Suspense would be if you show the audience the bomb and that it is going to go off in a few minutes then have the oblivious characters have their normal conversation and the audience is now helpless to warn the characters on screen of what they now know is going to happen.
