MARC21-007: Generation of motion picture
duplicate
Duplicate that is usually negative, referred to as a dupe neg, and is a reproduction of the original picture or sound track. A duplicate negative is made from a master positive, which in turn was made from an earlier negative.
d
A duplicate is at least three generations from the original. Duplicate negatives may be prepared either to obtain characteristics not present in the original image, as in special effects work, or to protect and extend the production availability of the assembled original negative as when duplicate negatives are prepared for release printing simultaneously at different labs.
master
Master that is usually positive and referred to as a master positive. It is a specially prepared positive print made from an earlier generation negative film and used for the preparation of duplicate negatives rather than for projection.
e
The master is normally considered second generation material.
original
Original that is usually negative. It is film exposed in a camera and thus of better quality than any subsequent generation or derivative.
o
When referring to older film, an original is almost always a negative. However, the original film may also be a reversal positive.
other
Generation other than duplicate, master original, reference print/viewing copy.
z
reference print/viewing copy
Reference print (ref print) that is defined technically as a release print which has been approved by the producer and director of a film. A reference print may also mean a print kept as a reference print to evaluate the quality of subsequent prints. In film archives, the term is used to indicate that a film may be viewed by researchers.
r
It is not original, master, or duplicate material.
unknown
Generation stage of the film is not known.
