SMPTE timecode on a clapperboard. SMPTE timecode (/ ˈ s ɪ m p t iː / or / ˈ s ɪ m t iː /) is a set of cooperating standards to label individual frames of video or film with a timecode. The system is defined by the Society of Motion Picture and Television Engineers in the SMPTE 12M specification. SMPTE revised the standard in 2008, turning ...
The SMPTE family of timecodes are almost universally used in film, video and audio production, and can be encoded in many different formats, including: Linear timecode (LTC), in a separate audio track; Vertical interval timecode (VITC), in the vertical blanking interval of a video track; AES-EBU embedded timecode used with digital audio
Vertical Interval Timecode (VITC, pronounced "vitsee") is a form of SMPTE timecode encoded on one scan line in a video signal. These lines are typically inserted into the vertical blanking interval of the video signal.
A special bit in the linear timecode frame, the biphase mark correction bit, ensures that there are an even number of AC transitions in each timecode frame. The sound of linear timecode is a jarring and distinctive noise and has been used as a sound-effects shorthand to imply telemetry or computers .
The Society of Motion Picture and Television Engineers (SMPTE) (/ ˈ s ɪ m p t iː /, rarely / ˈ s ʌ m p t iː /), founded in 1916 as the Society of Motion Picture Engineers or SMPE, [1] is a global professional association of engineers, technologists, and executives working in the media and entertainment industry.
It proposed removing the optical soundtrack from film prints, and using the SMPTE 80 bit timecode printed onto the film print, combined with two CD-ROM drives to provide a four channel digital soundtrack. The removal of the soundtrack would also allow more of the film area to be used during filming, increasing the quality. The format was not ...

The DVCAM SDTI has video data at the top, control data in the middle (Timecode, etc.) and audio at the bottom just like it is organised on the tape. Because SDTI is used for compressed data the area used is less than a full screen; this allows for faster than realtime transfers. SDTI is standardized as SMPTE 305M.
