2. In filmmaking, the 180-degree rule is a camera technique
which relates to a scene between two characters as they
speak to one another. The technique involves an invisible
axis which connects the characters together, by keeping
you camera at either side of the axis for the whole scene,
the characters will always be on opposite side of each
other. If you switched between either sides of the axis it
would make the audience disoriented and confused.

3. In filmmaking, the Shot reverse shot is a film technique where
there's a scene of one character looking at another
character usually off-screen and the next scene shows the
other character looking back. This creates an effect when
played back which makes the viewer assume the
characters are looking at each other.

4. In filmmaking, the Match on action is a film technique where
the editor cuts from one shot to another shot which matches
the first shots action or in other words creates continuity.
These two shots may have been shot hours apart but when
edited together it gives the impression of continuous time
when watched together.

5. In filmmaking, the cut away is a film technique which is the
interruption of a general filmed sequence by inserting a view
of an object or character which gives the audience clues to
the narrative. Sometimes the shot is then followed by a cut
back of the first shot, when the cutaway avoids a jump cut.
