AI video examples made from start and end frames
Every reel here was built shot by shot on Keytween: a start frame, a painted end frame, and the motion rendered between them. Open one to see its prompts, references and takes.

One tripod view of a mountain lake and its cabin, three shots, a whole night. Afternoon slides into alpenglow and the cabin lights come on; the sky goes black and fills with stars until the Milky Way arches over the peak; then the stars fade, mist forms on the water and the lights go off for sunrise. Each end frame is the previous frame repainted at a later hour, so the cabin, the rocks and the peaks never move. Birdsong, lapping water and a night chorus of crickets are generated with the picture.

The tin robot was generated first as a product shot on white, then placed on a study desk by naming @robot in the opening prompt: the teal body, red chest panel, glass eyes and wind-up key all carry over. Shot one lets dusk fall and clicks the banker's lamp on. Shot two lights up the robot's eyes and turns its head to the camera while the desk stays still. The lamp click and the creak of the turning head come from the generated sound.

A painted mountain village through one night of snow. Dusk deepens, the chalet windows light up one by one and the first flakes begin to fall; then the snow eases, the sky pales to morning, the lights go out and chimney smoke rises. Each end frame is the same painting with different weather, so nothing on the slope changes. A winter wind and a slow church bell play under both shots.
Gouache illustration · 3:2 · 2 shots · 10.67 s
A plasticine fox on a stump in a felt forest. It turns its head to the camera, blinks and smiles, then grows drowsy and dozes off with the same smile. The set, the stump and the body are identical in every start and end frame; only the head and face move.
Claymation · 4:3 · 2 shots · 8.00 s
A locked-off close-up of a woman at the window of a night train. She turns from the dark glass to meet the lens, then a slow smile arrives. Both end frames are edits of their start frame, so the face, the hair and the coat hold across the cut. The clatter of the rails is generated with the picture.
Cinematic portrait · 2 shots · 8.33 s
A frosted bottle on a wet stone slab. Shot one is a light reveal: the bottle starts in near darkness and the warm key light rises until the liquid glows and a caustic spreads on the slab. Shot two lifts the cap straight off the bottle to float above the nozzle. The bottle, the slab and the droplets never move; a bass swell and a glass chime are generated with the picture.
Commercial product hero · 2 shots · 7.33 s
A vertical summer moment in a sunflower field, drawn like classic cel animation. She smiles at the camera as a gust sweeps in: she tips her hat down against the wind, petals fly past and she comes up laughing. Then the wind dies down, her hair settles and she finishes on a soft smile. Wind, cicadas, her laugh and a gentle piano are generated alongside.
