Veo 3.1 prompts, references, and results
Text-to-video · no reference image
Prompt
A handheld shot follows a wok as it’s expertly flicked, sending vibrant, sizzling vegetables tumbling over themselves in a flash of motion and steam. Audio: a metallic clank and a sharp whoosh.
Prompt
Camera soars through the barn to the cowboy riding away.

Prompt
A medium shot frames an old sailor, his knitted blue sailor hat casting a shadow over his eyes, a thick grey beard obscuring his chin. He holds his pipe in one hand, gesturing with it towards the churning grey sea beyond the ship's railing. "This ocean, it's a force, a wild, untamed might. And she commands your awe, with every breaking light."
