Tying shoelaces

Natural lace contact and knot-tying, all 5 fingers stable throughout.

Natural pinch/lace contact, all 5 fingers stable, no fusion or clipping.

Ten normal digits across both hands, natural contact with laces and leather.

Ten normal digits across both hands, no clipping or melting into laces or leather.

Real-footage-quality contact with laces; no artifacts.

Five fingers on both hands and a finished bow at the end, but the clip cuts to a closer angle at about 5 seconds. Checked frame by frame.

Both hands keep five fingers while the laces cross, and the bow is finished by the end of one continuous take.

Ends with a finished bow, which few models reach, and finger counts hold during the crossings. The clip cuts to a close-up at about 3.7 seconds, a second shot that was not requested.

Knot shape morphs slightly as it tightens, otherwise clean.

Hands stay on-screen and tie correctly throughout; the only real artifact is one lace segment held stiff and straight rather than draping naturally near the end.

Correct anatomy, but the knot morphs together unnaturally rather than being threaded.

Good finger anatomy, but the lace ties by morphing/fusing into a finished bow rather than real topological pulling.

Plausible two-handed lacing with correct finger counts, but there is no finished bow by the end of the 8 seconds and the lace motion goes soft during the crossings.

Hands blend/clip into laces then vanish entirely around 00:05 as the knot finishes tying itself. Verified via frame extraction: last frame shows a complete finished bow with no hands in shot at all -- confirmed, not a judge hallucination.
