Film continuity:
This is where all of the scenes are edited and filmed so that they run continuously and looks like it could be real life, where there are no things like jarring or actions being repeated.
180 degree line of action:
This is a rule when filming a scene. This is an imaginary line that should not be crossed, as to the audience it would look like the characters positions would have changed places and would be confusing. For example if two people were
having a conversation, the characters positions would seem to keep changing.
Shot-reverse shot:
This is where the camera
would be pointing at one person who is possibly talking and would changes shots to another person who is talking and keep going back and forth for the duration of the dialogue, for example, in a two way conversation where the characters aren't able to both get in the same shot.
Match on action:
This is where the scene frames are cut
properly to show a continuous action and would follow through like it would in
real life.
