Video

A barista with a shaved head and a small scar above his right eyebrow stands behind a marble counter, facing camera. He picks up a copper pitcher and pours milk into a white ceramic cup until it is three-quarters full. As he pours, a customer in a red coat walks left to right between the camera and the counter, fully hiding him for about one second, then continues out of frame. The barista is still pouring, same cup, same hands. Behind him a chalkboard sign reads "FLAT WHITE 18". The camera performs a slow dolly-in on a 35mm lens, from waist-up to chest-up, at constant speed. Continuous take, no cuts.

What each clause is testing

a shaved head and a small scar above his right eyebrow

Identity persistence. A specific, small mark that has to survive the occlusion and come back on the correct side.

pours milk into a white ceramic cup until it is three-quarters full

Fluid behaviour and volume accumulation. The level must rise, and the stream must connect pitcher to surface.

fully hiding him for about one second, then continues out of frame

Object permanence. The single hardest test in video, and the one a cut is usually used to hide.

The barista is still pouring, same cup, same hands

State continuity across the occlusion. Most models resume with a different pose, cup or hand count.

a chalkboard sign reads "FLAT WHITE 18"

Temporal text stability. Letters must hold still across the dolly instead of crawling frame to frame.

slow dolly-in on a 35mm lens, from waist-up to chest-up, at constant speed

Camera control fidelity. A real dolly changes parallax. A fake one is a crop, and the background gives it away.

Continuous take, no cuts

Removes the escape hatch. A model that cuts here is failing the permanence test, not solving it.
