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 ...
Linear (or Longitudinal) Timecode (LTC) is an encoding of SMPTE timecode data in an audio signal, as defined in SMPTE 12M specification.The audio signal is commonly recorded on a VTR track or other storage media.
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.
Control track longitudinal timecode, or CTL timecode, developed by JVC in the early 1990s, is a unique technique for embedding, or striping, reference SMPTE timecode onto a videotape. Similar to the way VITC timecode is embedded in the vertical interval area of a video signal, CTL timecode embeds SMPTE timecode in the control track area of ...
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.
MIDI time code (MTC) embeds the same timing information as standard SMPTE timecode as a series of small 'quarter-frame' MIDI messages. There is no provision for the user bits in the standard MIDI time code messages, and SysEx messages are used to carry this information instead. The quarter-frame messages are transmitted in a sequence of eight ...
This enabled the music workstation to generate effects such as reverb or chorus within its hardware, rather than relying on external devices. SMPTE Since the primary users of the high-end workstations were film composers, the music workstations added hardware and software to generate SMPTE timecode, which is a standard in the motion picture ...
SMPTE 2059-2 is a PTP profile for use in synchronization of broadcast media systems. [15] The AES67 audio networking interoperability standard includes a PTPv2 profile compatible with SMPTE ST2059-2. [16] Dante uses PTPv1 for synchronization. [17] Q-LAN [18] and RAVENNA [17] use PTPv2 for time synchronization.
