In video engineering, color framing refers to the sequence of fields in a composite video signal, which governs the timing of the chrominance subcarrier and the color burst. Different standards like PAL, NTSC, and SECAM define distinct color frame sequences, critical for maintaining color accuracy during videotape editing. To avoid color artifacts from mismatched signals, the SMPTE time code includes a color framing bit that helps synchronize edits. Although largely a historical concern, color framing's significance has diminished with digital advances like timebase correctors and modern digital video systems, where subcarrier phase is no longer critical.
