Grok Imagine 1.5

Macro shot of an iridescent beetle crawling over a dew-covered leaf, rainbow shell and droplets crisp, morning light

A corgi in sunglasses bombs a hill on a skateboard past pastel houses, tongue flapping, fisheye lens, punchy saturated color

A neon-lit drag race between a vintage muscle car and a tuk-tuk on a rain-slick strip, wheels spin, the crowd roars, synthwave color grade

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.
