instantiationGenerations Vocabulary


  • A-B rolls:
    Reels of film used as an intermediate step in the production process to create transitions, fades and dissolves in the final production. Each roll contains distinct shots, with black leader in between to account for shots which will be dissolved in from other reels of film for the final production. Some film productions may utilize several such reels, labeled as A, B, C, D, etc. ‘A-B rolls’ should be used as a broad term for any such reels.
  • Answer print:
    The version of a film that is printed to film after color correction and with the sound properly synced to the picture, generally used as the last production element before final approval for release.
  • Composite:
    Refers to the combination of several original rolls or elements in one print or negative — for example, a reel with the combined sound and image or a composite track that includes music, effects and dialog.
  • Copy:
    A general term for an item that has been reproduced or duplicated from an original instantiation.
  • Copy: Access :
    An instantiation of an asset, typically of low quality, that is designated by an archive or library for use by patrons, researchers, etc.
  • Dub:
    An analog copy from a film, videotape or audiotape master instantiation or earlier generation, typically involving some generation loss.

  • Fine cut:
    A working edit of a film or program which contains the correct sequences in the correct order, but may still undergo revisions in scene and sequence order to refine the final visuals.
  • Intermediate:
    A broad term for a reel of motion picture film, such as an intermediate positive or intermediate negative, that exists as a generational step between the original negative and a release print. This term should be used in conjunction with a generation element reading ‘positive’ or ‘negative’. More specific terms may also be used, such as interpositive, IP or master positive for intermediate positive; internegative for intermediate negative; or CRI for color reversal intermediate.
  • Kinescope:
    A recording of a live television program on motion picture film, used for the purpose of recording programs before the wide adoption of videotape.

  • Magnetic track:
    An analog sound recording stored on a reel of film with a magnetic coating.
  • Master:

  • Mezzanine:
    A version of an asset which is not the master, but is of high enough quality to be used for editing and to generate access copies.
  • Negative:
    A version of a film asset recorded with colors inverted. Most motion picture film is originally shot in negative.
  • Optical track:
    An analog sound recording stored on film by printing a waveform on a film strip.
  • Original:
    The first generation of an instantiation — either the material that came directly from the camera, in the case of raw footage, or, in the case of an edited master, the first master version created.
  • Original footage:
    Raw footage that was shot directly on camera, before dubbing, editing, or reformatting.
  • Original recording:
    Raw audio that was captured directly, before dubbing, editing or reformatting.
  • Outs and trims:
    Negative or positive prints of materials used for the production of a motion picture film but not included in the final version, such as outtakes, second takes, tests, sound and dialogue tracks, etc.
  • Picture lock:

  • Preservation:
    Typically the highest-quality version of an asset in the possession of a library or archive, which is not accessed, but instead kept for the purposes of long-term preservation. A preservation instantiation may be a preservation master, which is considered the original or most important version to preserve, or a preservation copy, which exists as an exact or near-exact duplicate of the preservation master in case of destruction or damage, and which is often used to make mezzanine or access copies.
  • Print:
    A film that contains a positive image printed from a duplicate negative or a reversal film, intended for projection.
  • Proxy file:
    A lower-quality instantiation of an asset, such as a preview, that is provided to allow users to review files before accessing the original. May be the same as an access copy.
  • Reversal:
    A type of moving image film that directly produces a positive image on the camera original, rather than a negative.
  • Rough cut:
    An early edit of a film or program which contains the approximate shot selection and timing that will be used for the final version, but may still require significant editing for sound, color, titles, etc.
