a) Device used to correct for time base errors and stabilize the timing of the video output from a tape machine.
Machines like VHS players where a single pass of the video head represents many video lines are particularly susceptible to tape stretch, jitter, and speed variations which cause some recorded video lines to be shorter or longer than others. The TBC acts as a “rubber-band” storage device to line up each horizontal line at its proper location allowing for synchronous playback.
b) A device used to rectify any problems with a video signal’s sync pulses by generating a new clean time base and synchronizing any other incoming video to this reference. The Digital Video Mixer includes two infinite window, full field TBCs.
Industry:Software
In many situations, video losses can be anticipated, allowing signal precompensation in a way that partially corrects for the losses. See Line Compensation.
Industry:Software
The act of changing the effective resolution of the image.
Images can be scaled down so that more images can be displayed or scaled up such that the image takes up more screen space.
Industry:Software
a) Two images simultaneously picked up by two different cameras and electronically mixed on the face of a kinescope tube in such a manner that both images are visible. b) A film term describing the mixing of two or more video sources such that they appear to be overlaid.
Industry:Software
A video signal that will remain legal when translated to any other format. A valid signal is always legal, but a legal signal is not necessarily valid. Signals that are not valid will be processed without problems in their current format, but problems may be encountered if the signal is translated to a new format.
Industry:Software
The list of directories that leads you from the root (/) directory to a specific file or directory in the file system.
Industry:Software
A display showing hours-minutes-seconds of tape that has been recorded (elapsed time), or how much tape remains.
Industry:Software
a) To label with a take number by recording a voice on the tape.
b) Term used for a frame of video text usually recorded after bars prior to countdown sequence at the top of a commercial or program containing information on date recorded, ad agency, direction, etc.
Industry:Software
a) A digital code number recorded onto a videotape for editing purposes. When decoded, the time code identifies every frame of a videotape using digits reading hours:minutes:seconds and frames. Each individual video frame is assigned a unique address, a must for accurate editing. The three time code systems used for video are VITC, LTC, and RC (consumer). b) Electronically generated digital clock information which is recorded onto tapes on a special track such that an editor can accurately locate individual frames (fields) of video information for editing purposes.
The SMPTE standard for encoding time in hours, minutes, seconds, and frames and video.
