Time Sound Effects to Visible Events
Write the sound event beside the action that should trigger it, then describe the environment and camera treatment. Start and end frames can further define the visual route. Review timing, continuity, and the audio mix as separate approval points.
| Start Frame | End Frame | Prompt | Generated Video |
|---|---|---|---|
 |  | A cinematic shot of a heavy thunderstorm hitting a futuristic neon city. The sound of thunderclaps and rain hitting metallic surfaces is perfectly synced with the flashes of lightning. |
Direct Fast Motion With Physical Cues
Specify speed, surface, camera tracking, and the material response expected from the action. Concrete cues such as water spray help define what the frame must communicate. Inspect subject shape and background continuity through the entire move.
| Prompt | Generated Video |
|---|---|
A high-speed F1 car drifting around a sharp corner on a wet track. Water sprays realistically from the tires, and the camera follows the drift with a professional cinematic pan. |
Write the Scene in the Working Language
A native-language brief can preserve cultural and visual terms that become awkward after translation. Include wardrobe, location, movement, light, and mood as usual. Review the resulting scene with a fluent speaker when words or spoken audio matter.
| Prompt | Generated Video |
|---|---|
(Chinese Prompt) 一位身着汉服的少女在盛开的梨花树下漫步，花瓣随风飘落，阳光穿过树叶洒在她身上，意境唯美动人。 |
Preview a Multi-Shot Story Beat
Happy Horse can produce a compact sequence that reads as more than one static setup. Use this for pitching the rhythm of a short ad or cinematic transition. Treat it as a concept clip and verify continuity before relying on it as final video.
