How the app finds similar videos

Each second of a clip is reduced to an 8×8 color grid. Two such fingerprint strips are compared. The higher the similarity, the more likely the videos are duplicates.

Comparison

Shift mimics clips that start slightly earlier or later. The app tries every shift and picks the best match.
