    The process of making a new negative of a film by striking an interpositive and then, from that, a new negative -- the internegative. In recent years, this two-step process was replaced by the CRI process. But advances in the IP/IN stocks now make this a preferable method for release printing.

I.P. (Inter-positive) Print
    A release print from an I.P., as opposed to an EK print.

Image clip
    A copy or instance of a source image. Each time you use a source image, an image clip of it is created. You can have as many clips of the same source as you need. You can then manipulate the clip without affecting the original source image.

iNEWS ControlAir
    A machine control system for on-air operations (iNEWS ControlAir), which can be integrated into the iNEWS newsroom computer system or operate as a standalone environment.

    White-coated film which is used at the heads and tails of film and soundtrack. It serves several purposes. It protects the film itself since it is wound on the outside of the reels rather than the valuable picture. It also provides the thread-up necessary for projection. Since it can be easily written on, it is also used as identification.

Legal effects
    The lengths for fades and dissolves which can be executed by most printers (16, 24, 32, 48, 64 and 96 frames).

    A technique for displaying widescreen video on a screen with a different aspect ratio by adding black borders above and below the original frame.

    When video is stored on normal video tape it is done so in a linear fashion. This means that one scene follows another in a sequential order. With non-linear editing the video information is stored on the hard disk in the computer and you can record scenes in any order. This is because it is possible to access the material on the hard disk almost instantly and randomly.

Linear editing
    A type of tape editing in which you assemble the program from beginning to end. If you require changes, you must rerecord everything downstream of the change.

    That point in the editing of the film when the picture editing is over. The cut is then "locked."

Low-Con print
    A print that is made on a print stock which has been flashed evenly white light prior to the image being exposed on it. This yields a lower contrast print (brings up the black levels) which in turn yields a more attractive video transfer.

Low resolution
    The digital video of a resolution suitable for edits or distribution over a network, but not for broadcast.

LTC Longitudinal timecode
    A type of SMPTE timecode that is recorded on the audio track of a videotape. LTC can be easily read when the tape is moving forwards or backwards but not at freeze frame.

Matched cut
    A cut joining two shots whose compositional elements match, helping to establish strong continuity of action.

Matte Shot
    An optical in which part of one shot is combined with part of another to create another shot which did not exist to begin with. An example would be taking a shot of an astronaut shot in a studio, combining it with a shot of a scene which appears to be on the moon.

Master shot
    A shot which covers an entire piece of dramatic action (usually a long shot, or wide shot).

Match-frame edit
    An edit in which the last frame of the outgoing clip is in sync with the first frame of the incoming clip, such that the incoming clip is an extension of the outgoing clip.

    The process allowing you to generate a film cut list from a 30-fps video project that uses film as the source material.

    A grayscale image that defines the transparency of an image when it is composited over another. A matte can be part of the image itself (alpha channel) or derived from another image (external matte).

Non-drop-frame timecode
    An SMPTE timecode format that continuously tracks NTSC video at a rate of 30 fps without dropping frames to compensate for the actual 29.97-fps rate of NTSC video. As a result, non-drop-frame timecode does not coincide with real time.

    Pertaining to instantaneous random access and manipulation of any frame of material on any track and on any layer of an edit sequence.

Nonlinear editing
    A type of editing in which you do not need to assemble the program from beginning to end. The nature of the medium and the technical process of manipulating that medium do not dictate how the material must be physically ordered.

    National Television Standards Committee created the first international television system for use in the U.S. and other countries. It produces pictures by creating 525 alternating lines across the TV screen for each frame of video. Since PAL and SECAM, the other two world systems, were developed later, they took advantage of better technology. Insiders joke that NTSC means "Never the Same Color."

Reference background
    An image or animation file used to help position objects in a scene. The reference background appears behind all objects.

Reference clips

Registration I.P.
    A certain type of interpositive which is printed in so particular a manner that the I.P. can be used as a replacement negative. For this reason, a registration I.P. is made whenever the original negative is being removed from the lab, so as to have a protection in case something were to happen to the original negative. A registration I.P. is, therefore, sometimes called a "protection I.P."

    24p segmented frame. Video captured in a filmlike way, formatted for digital recording. Like film, the images are then recorded to tape as two temporally coherent fields (segments), one with odd lines and the other with even lines.


    25-fps progressive media.

2D layer
    A layer in which objects are stacked on top each other. Objects cannot intersect in this type of layer.

2D textures
    Images that are mapped to the object surface. An algorithm is used for “wrapping” the texture around the object’s surface so that the pattern curves and distorts realistically.

3/4-inch U-matic
    One of the first composite videocassette formats, in which the composite signal is recorded onto 3/4-inch tape. Used for many years, particularly in field recording, the U-matic format is slowly being replaced by more advanced and lightweight systems.

3D compositing
    Compositing which takes place in the Z plane depth.

3D layer
    A layer in which objects are positioned based on their locations in three- dimensional space. Objects can intersect in this type of layer.

3D manipulators
    A set of 3D controls that allow you to manipulate primitives, properties, and operators in a viewport. Manipulators provide “handles” that can be directly moved in 3D space to modify specific parameter values.

3D objects
    Anything with a position and a representation in 3D space. Some objects have a special role, such as cameras and lights, while others serve as controls for other objects, such as waves and manipulators.

3D textures
    Also called solid textures. A 3D texture is created by a computer procedure with a set of parameters instead of a picture file.

4:2:2 digital video
    A digital video system defined by the ITU-R 601 (CCIR-601) technical documentation. 4:2:2 refers to the comparative ratio of sampling of the three components of the video signal: luminance and two color channels.

    The method of recording and playing back Dolby Stereo sound for film. The tracks are mixed down from their four-track format to a two-track form. It is this two-track version that is transferred to optical track and married with the picture. At the theaters, Dolby equipment expands the two tracks back into four.

    A surround sound system that uses three speakers across the front (right, left and center) and two stereo speakers in the rear (right and left), along with a subwoofer.

    720 lines, progressive scan. Resolution is 1280 x 720, scanned at 60 Hz.
