Drift is dangerous precisely because it is invisible at the frame level. Reviewed one at a time, every image passes. Played in sequence, the jaw has narrowed, the can has grown a millimetre and the key light has swung fifteen degrees.
Every gate we run exists to catch it: stack and flick for faces, silhouette overlay for products, one stated key direction for a set. The rule underneath all three is the same: compare against the locked reference, never against the previous frame, because comparing to the previous frame is how drift accumulates unnoticed.
QUESTIONS PEOPLE ASK
How do you stop AI image drift across a series?
Lock a master reference before the set exists and generate everything from it. Then check each new frame against that reference, not against the last one you liked.
