Shot

A Shot is:

(1) A piece of film that has been exposed without cuts or interruptions (before editing).

(2) A trimmed piece of uninterrupted film that is used in the final version of a film (after editing). 

In both cases, the shot is the basic element of a film, defined by its physical (including digital) existence as an unbroken entity (or its appearance as such for the viewers). It may be of any duration, from a fraction of a second to minutes and even hours. A lengthy shot with a duration of more than approximately 40 seconds is called a long take.
