Continuity 

2. Continuity, in film, refers to the concept that the positions of objects onscreen as well as their colors and sizes, etc. must remain consistent; continuity errors break the illusion of watching actual events. Care towards continuity must be taken because films are rarely, if ever, filmed in the order they are presented in: that is, a crew may film a scene from the end of a movie first, followed by one from the middle; the shooting schedule is sometimes dictated by weather, permitting issues, or other circumstances besides preference. Frequently film shoots will have a person dedicated exclusively to minding continuity.

One example of broken continuity occurs in the 1998 film Waking Ned Devine[?], when two of the characters are walking through a storm to Ned's house: the umbrella they are under is black during their conversation on the walk to the house (filmed from slightly above and to the front); yet after cutting to a lower shot from behind of Jackie approaching the house, Michael walks onscreen from the right holding an umbrella that isn't black but beige, with a brown band at the rim.

Continuity also matters in other forms of art, such as novels and comics. If a character loses his jacket in one scene, yet he is still wearing it in a later scene without recovering it or getting another one, that is a break in continuity.

In a larger sense, continuity refers to consistent details of any fictional world, such as the names of characters' relatives.

Accidental or deliberate discrepancies in continuity are known as retconning.
