Athletic Archive Chroma Delay Correction for Historic Game Video
Athletic archive chroma delay correction is the process of identifying and fixing a timing misalignment between the color signal and the brightness signal in analog game footage — a defect that causes team uniform colors, jersey numbers, school banners, and court markings to appear shifted horizontally from their correct position on every display that plays the affected file. Composite analog video encodes brightness (luminance, Y) and color (chrominance, C) as separate signal components that must arrive in precise synchronization. When the capture deck, the tape mechanism, or the time base corrector introduces a timing offset between those two components — even by a few hundred nanoseconds — the chroma channel drifts sideways relative to the luma channel, creating color fringing along every high-contrast edge in the frame. On a lobby kiosk or hall-of-fame screen, this looks like a red or blue shadow beside a white jersey number, or school color bleeding slightly away from the correct position in a banner or court logo.
