More from each model

Kling O1

A dancer spins in a mirrored studio, her skirt flares and the reflections track every turn, soft daylight, slow dolly in
A cyclist descends a mountain switchback, the camera follows from behind and leans into each turn with him, pine forest and morning haze
A street market at noon, a vendor hands fruit to a customer while a cyclist passes in the foreground and a dog trots across frame, static wide

Seedance 2.5

0–2s: close-up of a barista's hands tamping espresso, warm tungsten light. 2–4s: milk pours into the cup, a rosetta forms in slow motion. 4–5s: she slides the cup across the bar toward camera and smiles, shallow depth of field
Wide shot of a mountain lake at dawn, mist lifting off the water, a loon calls and the sound echoes, a fish breaks the surface with a soft splash, slow push-in, natural ambience on frame
0–2s: a skateboarder drops into an empty concrete bowl at golden hour, low handheld follow. 2–4s: the camera swings around as she carves the wall, sparks of dust in backlight. 4–6s: she pops out and lands a clean stop, dust settling, one continuous shot, no cuts
