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 ...

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.
The sync pattern in bits 64 through 79 includes 12 consecutive 1 bits, which cannot appear anywhere else in the time code. Assuming all user bits are set to 1, the longest run of 1 bits that can appear elsewhere in the time code is 10, bits 9 to 18 inclusive. The sync pattern is preceded by 00 and followed by 01.
The checksum in bits 82–89 is a simple bytewise XOR of the previous 82 bits (including the sync bits, so bit 82 is the XOR of bits 74, 66, ..., 2), which can be described as a CRC with generator polynomial x 8 +1. (Preset to zero, no inversion.) The exact nature of the color frame sequence depends on the video standard being used.

SMPTE color bars are a television test pattern used where the NTSC video standard is utilized, including countries in North America. The Society of Motion Picture and Television Engineers (SMPTE) refers to the pattern as Engineering Guideline (EG) 1-1990. [1] Its components are a known standard, and created by test pattern generators.
