Editing Timecode (section)

== Video and film ==
In [[video production]] and [[filmmaking]], [[SMPTE timecode]] is used extensively for [[synchronization]], and for logging and identifying material in recorded media. During filmmaking or video production shoot, the [[camera assistant]] will typically log the start and end timecodes of shots, and the data generated will be sent on to the editorial department for use in referencing those shots. This [[shot-logging]] process was traditionally done by hand using pen and paper, but is now typically done using shot-logging software running on a laptop computer that is connected to the timecode generator or the camera itself.

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]]
*[[Burnt-in timecode]], in  human-readable form in the video itself
*[[CTL timecode]] (control track)
*[[MIDI timecode]]

[[Keykode]], while not a timecode, is used to identify specific [[film frame]]s in film [[post-production]] that uses physical [[film stock]]. Keykode data is normally used in conjunction with SMPTE timecode.

[[Rewritable consumer timecode]] is a proprietary consumer video timecode system that is not frame-accurate, and is therefore not used in professional post-production.
