Continuity

In this clip from The Birds it has been edited so to a viewer it continuously flows in real time. This has been well done in the sequence of shots because they have obeyed the 180 degree rule so in each shot they would film from angles within 180 degrees. This is done so it is simple for the viewer to understand what is going on.

Before entering the house it seems very safe and calm this is because they are using shots spread well apart and is a long shot being used so the viewer can see everything going on in the shot.
Once in the kitchen the viewer is starting to get the feeling that something has happened because they highlight the fact that all of the mugs have been smashed.
Then in the corridor it increases the tension because of it being very dark and gloomy. Also the fact that the corridor looks like it is getting smaller makes it feel like she is getting sucked into it.
Then in the bedroom the speed of the camera shots increases rapidly and this is to intensify the fear in the audience and to keep them on the edge of their seats.

When she is walking through the kitchen it shows how to use the 180 degree rule to great effect and how it helps guide the viewers through the shot. Also the shot when she is walking down the corridor and it seems as if the corridor is getting smaller it shows a great way of implying that it is all closing in on here and subtly telling the viewers that she is getting closer.
