SL-68 / Transitions Performed by Bodies

Exit / Enter Frame

Leaves frame right, arrives frame left somewhere else — matched on stride.

The brief

A body leaves frame right and enters the next scene frame left, with the stride matched across the cut so the two spaces read as continuous travel.

Why it's hard

The model decelerates or turns the walker toward camera before the exit, which destroys the vector the next shot needs to inherit.

The craft key

Vector continuity: same speed, same height, same direction, no deceleration into the cut.

Starter prompt

Built with the CEMI MediaMax system for Google Veo 3.1. Prompts stay in English — that is the language these models take instructions in. Treat it as a starting point and start varying it.

exit-enter-frame
Two shots engineered for one cut. Shot A: a courier in a stiff canvas jacket crosses a wet loading bay left-to-right and leaves frame right still mid-stride, never slowing. Shot B: that same stride enters frame left on a concrete stairwell landing, the foot meeting the tread on the exact beat the previous foot left. Vector, cadence and shoulder height match; the ground is different. Dirty foreground: a coiled orange extension cable and a dripping galvanised rail cross the lower third, soft. Shot in the shoulder-following register of the Dardenne brothers, lit only by sodium bay lamps and corridor spill. Handheld, 40mm vintage Cooke Panchro at f/2.4, halation blooming on the lamps, the operator's breathing audible in the frame's drift. Salt-bloomed concrete, chipped enamel handrail, wet boot prints. The camera holds the emptied frame half a beat before the cut, because it is waiting, not editing. 24fps.

Why it's built this way

The cut is invisible only if the body pays for it: same speed, same height, same direction of travel, and no deceleration before the exit. Ask for the empty frame on both sides of the cut — the held beat is what tells the eye the space continued. Changing the ground under identical footwork is what makes it read as travel rather than as a jump cut.

Watch for

The model slows or turns the walker toward camera before the exit, killing the vector; generate each half separately with the stride cadence stated in the same words so the two halves can actually be cut together.
