The aspect ratio of highdefinition television (HDTV) .  \n3D: Three-dimensional, or having appearance the appearance of three-dimensional depth. 3D images can refer to stereoscopic images (one image for each eye) or computer-generated images based on three-dimensional modeling.  \n4:1:1: A video compression ratio in which the chroma (color) is sampled at one quarter the rate of luminance (brightness) .  \n4:2:2: A video compression ratio in which the chroma is sampled at one half the rate of luminance.  \n4:4:4: A video compression ratio in which the chroma is sampled at the same rate as luminance.  \n4:3: The traditional television aspect ratio, 4 units wide and 3 units high. This aspect ratio is being replaced by 16x9 .  \n4:3 Safe: A method of shooting widescreen footage while still retaining a \"safe area\" that can be cropped and used for 4x3 aspect ratio.  \n5.1 Audio: A surround sound system that provides five separate audio signals: Left, middle, right, rear left, rear right. An additional low frequency (LFE) channel is also provided.  \n720p: A high-definition video format that has 720 lines of vertical resolution and uses progressive scanning.  \n3-point editing: an editing technique that uses a three“in”and“out” points (or marks) to determine how much source material will be edited into a specific location in a sequence.  \n3-point lighting: a common lighting technique that requires three instruments – a key light, a fill light, and a back light. The lights are arranged around the subject in triangular fashion produce portrait-type lighting.  \nA-roll: videotape that contains primary action footage and/or interviews. Used in A/B roll editing.  \nA/B Roll: The use of alternating scenes, recorded on separate videotape reels (an A roll and a B roll), to perform dissolves, wipes or other types of video transitions.  \nAGC (automatic gain control): Electronic circuitry that compensates for either audio or video input level changes by boosting or lowering incoming signals to match a preset level. Using AGC, changing input levels can output at a single constant setting.  \nambient sound: A representative sample of background audio (such as a refrigerator hum or crowd murmur) particular to a shooting location. Ambient sound is gathered in the course of a production to aid the sound editor in making cuts or filling in spaces between dialogue. Also called room tone or natural sound.  \nanalog: A continuously varying electronic signal. Audio and video analog signals stored on tape deteriorate with each copy or generation.  \nanalog recording: The common form of magnetic recording where the recorded waveform signal maintains the shape of the original waveform signal.  \nA-only edit: Audio-only edit, sometimes called a“radio” edit.  \naspect ratio: A measure of screen size as articulated by the ratio of width to height. HDTV is 16:9 .  \nStandard definition TV is 4:3 .  \naudio mixer: A component that combines more than one sound input for composite output.  \nB-roll: Video that consists of cutaways and other shots (usually with natural sound) that illustrate a story. If a reporter is talking about horseback riding in a news package, then the b-roll would be the shots of people riding horses.  \nbarn doors: Two-or four-leafed metal blinders mounted onto lights to control brightness or direction.  \nbit depth: The number of bits used to indicate the color of a single pixel in a bitmapped image or video frame. The higher the color bit depth, the higher the color precision. A higher color bit depth means more variety, more choices on how much color can be used for each pixel.
