Definitions for "Timecode"
A signal that contains information such as time, date, and other specific useful information which can be recorded and used as a time reference for bookkeeping and synchronization tasks. The popular SMPTE timecode is an 80 bit digital word that occurs once per video or film frame. SMPTE timecode is at a rate (about 5 kHz) that allows it to be recorded on audio tracks. Some devices (codecs, recorders, etc.) have special digital timecode tracks, while others just use analog tracks for this purpose.
With videos, a time stamp placed on each frame.
An electronic indexing method used for editing and timing video programs. Timecode denotes hours, minutes, seconds, and frames (00:00:00:00) elapsed on a videotape. Address track timecode is recorded simultaneously with the video picture. Longitudinal timecode (LTC) is recorded on an audio track. Vertical interval timecode (VITC) is recorded in the vertical blanking interval of the video track. SMPTE timecode is the prevalent standard. Other timecodes exist that include film timecode and audio timecode used during film projects. During editing, the Avid system can display and track several types of timecode.
