The 180 degree rule in filmmaking establishes an imaginary line between characters that the camera must not cross to avoid confusing the audience about the characters' positions. Crossing this axis is called "jumping the line." A match-on-action shot emphasizes continuity between shots by cutting at a moment of action. It allows focusing on a subject one character will interact with. A shot reverse shot alternates between characters' points of view in a conversation to maintain visual focus and avoid continuity errors caused by switching perspectives.

2. 180 Degree Rule
The 180 degree rule is an unwritten rule in filming, it is very important because it
avoids confusion.
There is an imaginary line that connects the characters in the mis-en-scene, this
is a line that mustn't be crossed at any time unless you pan it across while the
camera is recording, this gives the POV affect which makes it ok.
The first character will be camera left and the second camera will be camera
left, if they camera crosses the axis which connects the two characters then it is
called ‘Jumping the line’.

3. Match-on-action shot
A match on action shot is an editing technique
once you cut from one shot to another which
emphasizes the action in the previous shot.
The transition from the first shot to the second
creates a visual bridge which makes the viewers
focus on the match on action rather than the
continuity errors.
It allows you to focus on a subject which one of
the characters is about to interact with, this adds
affect without the viewers even contemplating the
shot.

4. Shot Reverse Shot
The shot reverse shot is used for editing, it takes the
viewers attention off of the continuity errors and
attracts their eyes to the conversation between the
characters.
Firstly it starts off with a POV shot or an OTS shot
which shows the viewers what the characters is
focusing on, it is usually followed by a shot revers
which shows the other character focusing.
The shot reverse shot is linked in with the 180 degree
rule, it ensures that there are no continuity errors in
the focus of the camera.
