Flim Terms
Aspect Ratio:
The relationship of width and height. When an image is displayed on different screens, the aspect ratio must be kept the same to avoid "stretching" in either the vertical or horizontal direction. For standard TV or monitor, the aspect ratio is 4: 3 yielding 160X120, 320X240 and 640X480 sizes. The HDTV video format has an aspect ratio of 16 to 9 (16: 9).
Background:
In a multi-layered video effect, the "backmost" layer, on top of which other layers are keyed or composited.
Background Plate:
The piece of film used as the basis for a visual effects shot. The background plate is then layered with one or more foreground elements, typically shot in front of a blue or green screen.
Blue/Green Screen:
A film or video technique in which an object or performer is taped against a blue/green-colored background. In post-production, the blue/green color is electronically removed, allowing images to be combined.
Color Correction:
In addition to color intensity, Imagine's artists can change the degree of contrast, highlights and shadows in a shot. This process, known as color correction, allows for the delicate adjustment of aspects that a cinematographer controls when shooting a film. Imagine''s artists can also perform "after the fact art direction" and add color to an entire scene.
Re-grainingDe-graining:
Grain refers to the small scale structure in a film image. It is caused by the small silver halide crystals that make up the active ingredient in the film emulsion. Imagine' artists can add grain or, re-grain a shot, which gives it a rougher, harsher look. Re-graining a shot can make new footage look like it was shot decades ago. Taking grain out, or de-graining, makes an image softer and smoother.
Digital Compositing:
The digital blending together of a background plate and one or more foreground elements to create one seamless, well-integrated film image
HDTV:
High Definition TV. A proposed standard for producing high resolution video, recommending the doubling of the current 525 lines per picture to 1050 lines and increasing the screen aspect ratio (width: height) from the current 12: 9 to 16: 9, which would create a television screen shaped more like a movie screen and provide image quality approaching 35mm film photography.
Image Processing:
Blurring, sharpening and touching up images digitally to enhance or correct a filmed scene.
Matte:
A solid color signal that may be adjusted for chrominance, hue and luminance. Matte is used to fill areas of keys and borders
Motion Tracking:
2D Motion Tracking is used for stabilization of unwanted camera weave or jitter, match moves between separate elements, and tracking features or objects within the film frame. 3D Motion Tracking divines the camera position within the 3D space of the shot, which allows the artist to integrate computer generated elements into the shot. Once the natural movement in both 2D and 3D have been determined, the elements can be composited together seamlessly.
Multimedia:
Refers to the delivery of information that combines different content formats (motion video, audio, still images, graphics, animation, text, etc.). A somewhat ambiguous term that describes the ability to combine audio, video and other information with graphics, control, storage and other features of computer-based systems
Post-Production:
All production work done after the raw video footage and audio elements have been captured. Editing, titling, special effects insertion, image enhancement, audio mixing and other production work is done during post-production. Videonics equipment is ideally suited for use in post-production
Rotoscope:
The frame-by-frame process of re-touching images in a live-action sequence. Often, animation is added over live-action via the rotoscoping technique
Special Effects:
Artistic effects added to a video production in order to enhance the production by creating drama, enhancing the mood or furthering the story. Special effects may vary from the limited addition of patterns or the mixing of several video images together, to sophisticated digital effects such as picture compression, page flipping and three-dimensional effects. Special effects are usually created using SEGs.
Storyboards:
A series of sketches, similar to a comic strip, which outlines the action and dialogue in a scene. These drawings would be pinned up on a bulletin board and arranged, re-arranged and replaced as the story took shape. Early rough storyboard sketches are referred to as Thumbnails, while more detailed drawings would be called Finished or Final Storyboard Panels.
Wire Removal:
The process of digitally painting out wires or cables attached to stunt people, vehicles or other objects in a filmed scene.
The relationship of width and height. When an image is displayed on different screens, the aspect ratio must be kept the same to avoid "stretching" in either the vertical or horizontal direction. For standard TV or monitor, the aspect ratio is 4: 3 yielding 160X120, 320X240 and 640X480 sizes. The HDTV video format has an aspect ratio of 16 to 9 (16: 9).
