Continuity in film and video involves maintaining consistent action and details across scenes. Editors should cut from one shot to another that matches the same action to avoid confusion. The 180-degree rule states that the camera should remain on the same side of an imaginary line between characters to avoid making it seem like they switched places. Shot reverse shot alternates between characters looking at each other to imply a conversation.

1. Continuity.
• The maintenance of continuous
action and self-consistent detail in
the various scenes of a film or
broadcast.

2. Match on action.
• Cutting on action or matching on action refers
to film editing and video editing techniques
where the editor cuts from one shot to
another view that matches the first shot's
action

3. 180-degre rule.
• Rule stating that a camera should be placed somewhere
inside 180 degrees on a particular side of the invisible line of
a shot containing two people filmed in sequence. If the
camera crosses the line, confusion results for the film
viewers, because it makes it look like the people are
switching places as one watches the film.

4. Shot and reverse shot.
• Shot reverse shot is a film technique where
one character is shown looking at another
character and then the other character is
shown looking back at the first character.
Since the characters are shown facing in
opposite directions, the viewer assumes that
they are looking at each other.
