More from each model

Runway Gen-4.5

A cork pops from a bottle, foam rises and spills over the lip, high-speed look, studio black background

Slow dolly in on a woman standing at a rain-streaked window, her reflection sharpens as the camera closes, cool daylight, locked vertical framing

A man in a grey wool coat walks toward camera down a cobbled lane as the camera tracks backward, his face and coat hold steady the whole take, overcast light

Static wide of a night highway overpass, cars stream beneath as light trails with natural motion blur, city skyline behind

Handheld two-shot of a glassblower and an apprentice at a furnace, the camera steps around them as the molten glass glows, faces and aprons consistent through the move

Veo 3.1

A long passenger train curves along a single track through a deep wooded valley at golden hour, low sun flaring between tall pines, wildflowers and long grass thrashing in the draught as the carriages pass. The camera tracks alongside at the speed of the train, the forest and a hazy ridge rising above it. Audio: steel wheels ringing on rail, a low horn far off down the valley, wind through grass.

Floodlights snap on one bank at a time over an empty football stadium at dusk, rain drifting through the beams, camera tilting up from the centre circle. Audio: four heavy contactor thuds, rain on plastic seats, a low wind through the stands.

A young woman stands inside a phone box at night, filmed from outside through rain-streaked glass, mouthing words into the handset. We never hear her voice. Heavy rain falls through the streetlight above, running down the panes and softening her face, wet road glinting in the foreground. The camera holds completely still. Audio: rain hammering on the roof of the box, water running in a gutter, one car passing far off. No speech, no music.
