Prompt:
A daring cat, wearing a safety jacket and goggles, speeds across the water on a jet ski, leaving a trail of splashes behind. Chasing close behind, two determined dogs, also in safety jackets, ride their own jet skis, their ears flapping in the wind. The cat grips the handlebars tightly, eyes wide with excitement, while the dogs bark playfully, closing the gap. The bright sun reflects off the waves, creating a thrilling high-speed chase on the open water.

Example 3: cat flying her jet
Input image:
Prompt:
A fearless tabby cat, dressed in a vintage aviator outfit with leather goggles and a pilot's scarf, grips the controls of an old retro biplane soaring through the sky. The wind ruffles its fur as it confidently navigates the aircraft, with a spinning propeller and a trail of white smoke behind. Below, rolling green fields and a golden sunset create a dramatic backdrop. The cockpit is filled with classic dials and levers, giving the scene an adventurous, nostalgic feel. The cat's focused eyes and determined expression make it look like a true flying ace.

Yes. Paid plans include a commercial license. If you're running it yourself, check the open-source license terms.
6. How long does it take to generate a video?
Depends on your GPU and settings.
- 5s of 480P video → ~4 min on a 4090
- Higher resolutions or longer videos take more time
7. What input formats does it support?
- Text (describe what you want)
- Images (use a reference image)
- Video (for editing)
8. Can it generate videos in different languages?
Yes. It supports English and Chinese text in videos.
