A basic sequence is a technique used in film-making to allow for each scene to be more interesting and it involves numerous clips of the same scene. It is achieved by splitting up a long scene with just one shot and angle to several shorter clips with varying shots and angles.
Over the Shoulder Shot
Each new shot should if at all possible involve a change in image size and camera angle. Not only does this make movies more interesting, but also makes it easier to cut between shots.
While varying shot angles and distances, it is also vital to follow the 180 degree rule.
Things to remember about the 180 degree rule
- The 180 degree rule is about viewer orientation. It starts with the establishing shot and works from there. If you create another establishing shot, then the orientations starts again from that direction.
- You can cheat the 180 degree rule in the following ways:
1. You can show the camera crossing "the line"
2. You can use a visual reference (like the ramp going up to the boat in the book)
3. You can cut on an action (like the character in the book putting on his hat
4. You can use a cutaway between two different reverse angles, to neutralize the orientation.
the 45 degree rule helps to avoid jump cuts.
What is Jump Cut? A jump cut occurs when the image size of two separate clips is changed but the camera angle is not altered. This can lead to jerky, unnatural-looking movements.
At 1:37 you can see that jump cuts can be used to create the effect of the camera moving forward. Note: the shower sequence from Psycho isn't considered classical Hollywood editing, because the edits aren't invisible.
The 45 degree rule (or 30 degree rule) helps avoid jump cuts
Note: the barebones book calls it 45 degree rule though it is most commonly called the 30 degree rule
Things to remember about the 45 degree rule:
•It makes transitions from shot to shot smoother and easier to accomplish
•If there is a subtle change in an image it will not be noticed if both shots are different enough
