A shot is a continuous piece of filming without interruption from the time the camera is turned on and starts filming until it is turned off.
In general most shots last for no more than 10 seconds.
The camera or subjects may move during a shot.
An edit is a break in the film where one shot ends and the next shot begins.
The four common types of edit are: cuts, dissolves, fades and wipes (occasionally).
Edit types are selected carefully to suit the genre of the film and emotional intention of the shot.
This is the combination of all the visual elements within the frame (frame: the physical boundary that contains what the audience sees)
