A Reddit user tested Google Flow's new Omni 1.2 Flash, which now generates up to 15 seconds per run, and produced a complete photorealistic sparkling-water ad from a single structured prompt (storyboarded first with GPT).

The shared prompt is a useful template: lock character and product details for consistency, then break the 15 seconds into timed beats, each specifying camera (35mm wide → 90-100mm macro), lighting direction, performance, and sound design. The result shows an ad-grade workflow: GPT storyboard + structured prompt + one-shot generation.
