Motion Critique Framework

Static images are evaluated on visual dimensions. Animation adds temporal dimensions: smoothness, timing, and motion personality. The motion critic evaluates five dimensions.

Temporal Consistency: does the visual style remain constant across all frames? Palette, typography, composition — all the static dimensions must hold across the time axis. Smoothness: are transitions free of jitter, jumps, or artifacts? Frame-to-frame delta should be perceptually uniform — no sudden jumps followed by slow crawls. Timing: do transitions match the motion style specification durations? A 200ms standard transition should not take 500ms or 100ms. Easing: do elements follow the specified easing curves? A linear motion where ease-out was specified is a violation. Motion Personality: does the overall feel match "confident and precise"? Bouncy, chaotic, or playful motion violates the brand motion specification.

Each dimension is scored 1-10. Minimum 7 per dimension to pass. Temporal consistency is weighted 2x because it is the most common failure mode and the most visible. The motion critic operates on a sampled frame set — not every frame, but every 10th frame plus all transition points (where the motion begins, peaks, and ends).
