Editing SMPTE timecode (section)

== Variants ==
Timecode may be attached to a recording medium in a number of different ways.
#[[Linear timecode]], a.k.a. longitudinal timecode (LTC): suitable to be recorded on an audio channel, or carried by audio wires for distribution within a studio to synchronize recorders and cameras. To read LTC, the recording must be moving, meaning that LTC is useless when the recording is stationary or nearly stationary. This shortcoming led to the development of VITC.
#[[Vertical interval timecode]], (VITC, pronounced "vit-see"): recorded into the [[vertical blanking interval]] of the video signal on each frame of video. The advantage of VITC is that, since it is a part of the playback video, it can be read when the tape is stationary.
#[[AES-EBU embedded timecode]], SMPTE timecode embedded in an AES3 digital audio connection.
#[[control track longitudinal timecode]] (CTL timecode): SMPTE timecode embedded in the control track of a videotape.
#Visible time code, a.k.a. [[burnt-in timecode]] and '''BITC''' (pronounced "bit-see") - the numbers are burnt into the video image so that humans can easily read the time code. Videotapes that are duplicated with these time code numbers ''burnt-in'' to the video are known as ''window dubs''.
#Film labels, such as [[Keykode]].
