Vanity credit

1.  A credit given to an individual who has had little or no actual involvement with the making of a moving image work.  Vanity credits are usually given to a person because of their position in the corporate hierarchy, such as the head of studio or company, or the head of a specific department, such as art or costumes (for instance, a person who assigns subordinates to individual films while still receiving credit).

2.  Also, redundant credits given when more specific functions (usually director or producer) are indicated; since the 1980s, a director of American features frequently receives an additional credit reading "a film by ..." at the opening, although final credits will specify function.

Viewing print

In AMIM2, a film print designated as available for screening.  This term can encompass flat bed and theatrical projection.  In the first edition of AMIM, the term "reference print" was used for this designation.  However, "reference print" is better known as a film print "made to optimum reference conditions, and with which series-produced release prints must conform" (ISO 4246: 1994).  In order to minimize confusion, "viewing print" is used in AMIM2 as an optional term that describes level of accessibility.  See also Theatrical projection print.
