## Example output

[Watch the clip](https://otoy.studio/images/models/kling-4-example.mp4) (1080p, 16:9, 5 seconds).

Prompt: A huge storm wave crashes against an old stone lighthouse on a rocky headland at dusk, white spray exploding high into the air as the lighthouse beam sweeps through the mist. Slow aerial push-in toward the tower. Dark teal sea, heavy clouds with a band of orange light on the horizon, cinematic 35mm film look. Sound of roaring surf and howling wind.
