More from each model

MiniMax H3

[Push in] A peacock fans its tail in a palace courtyard, every eye feather resolved, morning sun through the arches
[Static shot] Honey pours from a wooden dipper onto a stack of pancakes, folds and pools realistically, a pat of butter slides off the top, kitchen window light
[Zoom in] Wide shot of terraced rice fields at sunrise, mist in the valleys, a farmer walks the ridge with a hoe, fine texture in every terrace

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
