time code (TC)

The time code (TC) is a time information in videos and audios, which is needed for video editing and electronic editing. It is used in analog and digital video recording processes and is used for frame-accurate control. In video, time codes include time in hours (h), minutes (m), seconds (s), and frames

(f). The common form of representation is: hh:mm:ss:ff. Most time codes work with a relative time indication, but there is also

the real-time code, Real TimeCode (RTC). In video technology, the time code can be transmitted in the vertical blanking interval together with the video signal or recorded on a separate audio track. In addition to the time information in hours, minutes, seconds and full frames, the time code can also include other data

The time code is recorded synchronously with the audio and video information and used for editing as well as post-production. There are standardized time codes such as the SMPTE time code from the Society of Motion Picture and Television Engineers (SMPTE), the Longitudinal Time Code (LTC), MIDI Time Code (MTC), Inter Range Instrumentation Group (IRIG) as well as Burnt-In Time Code (BITC) and Vertical Interval Time Code (VITC) as well as proprietary time codes such as the RC time code defined by Sony for Video-8 and Hi8 video.
