In countries employing the SECAM standard, PAL format cameras and decks are used. sDI:Serial Digital Interface, a professional digital video connection format with a 270 Mbps transfer rate. SDI uses standard 75-ohm BNC connectors and coaxial cable. six-point edit: See Split edit. slide edit: An edit that adjusts the previous clip’s Out point and the next clip’s In point without affecting the clip being slid or the overall program duration. slip edit: An edit that adjusts the In and Out points of a clip without affecting the adjacent clips or affecting overall program duration. spatial compression: See Intraframe compression. speed: The playback rate of a video or audio clip compared to the rate at which it was recorded. split edit: A technique resulting in a clip’s video and audio beginning or ending at different times. Also see L-cut and J-cut. storyboard: A series of sketches or still images outlining material to be shot on film or video, or indicating a sequence of clips to be edited together. streaming: Process of sending digital media over the Web or other network, allowing playback on the desktop as the video is received, rather than requiring that the file be downloaded prior to playback. superimposition: A composite, or layered image involving transparency; see also compositing. s-Video: Super-Video, a technology for transmitting analog video signals over a cable by dividing the video information into two separate signals: one for luminance and the other chrominance. (S-Video is synonymous with Y/C video). telecine: Refers to the combination of process, equipment, and software used to acquire and convert film to video. temporal compression: See interframe compression. three-point edit: An edit in which a clip is inserted into a Timeline using three of the four In and Out points. The fourth point is automatically calculated by Adobe Premiere Pro. timecode: Time reference that identifies each video frame on a tape, used to locate video seg- ments and implement frame-accurate tape-to-tape editing. When video is captured digitally, the timecode is transferred to the computer. Though timecode is not necessary for frame-accurate editing on a computer, it can be used to build batch capture lists and locate source footage. timecode log: See Batch list. timeline: On an NLE interface, the graphical representation of program length onto which video, audio, and graphics clips are arranged. titler: See Character generator. track: In the Adobe Premiere Pro Timeline panel, a horizontal row on which clips are arranged. Tracks are similar to the layers found in many other Adobe applications. When clips are placed one above another, both clips play back simultaneously. The Video 1 track is the main video edit- ing track; all tracks above Video 1 are for superimposing clips over the Video 1 track; all tracks below Video 1 are for audio. transcoding: Converting a file from one file format into another; that is, reencoding the data. transition: A change in video from one clip to another. Often these visual changes involve effects where elements of one clip are blended with another. transparency: Percentage of opacity of a video clip or element.

For a comprehensive overview of Adobe Produc- tion Studio, please visit www.adobe.com/ uncompressed: Raw digitized video displayed or stored in its native size. products/premiere/main.html. For a comprehensive overview of Adobe After Vertical resolution: The number of horizontal scan lines (counting from top to bottom) Effects, please visit www.adobe.com/products/ that the electron beam draws across a television screen to form the picture. aftereffects/main.html. Video capture card (or board): Installed inside a computer, adds the functionality needed to digitize analog video for use by the computer. Using a hardware or software codec, the capture card may also compress video as it is captured and decompress video as it is played or transferred back to a videotape. Voice over: A voice, such as a narrator, coming from off camera. Widescreen: Any aspect ratio for film and video wider than the standard 4:3 format; previously used to refer to wide-aspect film formats; now typically used to refer to the 16:9 format, which is the standard aspect ratio for HDTV. xlR connector: A connector with three conductors used in professional audio applica- tions, typically with a balanced signal. Y/C video:A video signal in which the chrominance and luminance are physically sepa- rated to provide superior images (synonymous with S-Video). YCrCb: video signal comprised of three components: luminance (Y) and two chromi- A nance (Cr and Cb). YuV:Another term for YCrCb. zooming: Enlarging or decreasing the apparent size of the subject within the frame by either optical or digital means.
