Editing Techniques

Reaction Shot 

A cut to a shot of a character's reaction to the contents of the preceding shot to imply the display of some sort of emotion on the face of the actor being shown

Insert Shot

An insert is a shot of part of a scene as filmed from a different angle and/or focal length from the master shot. Inserts emphasise a different aspect of the action in the master shot due to the different framing

Buffer/Neutral Shot

A film technique of inserting a shot into a film to disguise a mistake, or a cut

Fade and Dissolve

Gradual fade from one shot to the next to possibly show either a sense of passing time or changing location

Superimposing

Two distinct images appearing simultaneously with one superimposed upon the other

Wipe

One shot is progressively replaced by another shot in a geometric pattern; used to show change in location

Stock/Library Shot

A single piece of footage that has been used in other films to save shooting new material
