Mode 1
Text-to-Video Guide
Text-to-Video (T2V) is the most flexible mode. You write a prompt, and HappyHorse-1.0 creates the full scene — visuals and native audio — in one pass.
Prompt Structure
[Subject] + [Scene/Environment] + [Motion] + [Camera] + [Mood/Audio]
Mode 2
Image-to-Video Guide
Image-to-Video (I2V) takes your reference image and animates it according to your prompt. HappyHorse-1.0 leads all models in Source Fidelity (9.5/10) — it preserves the look of your image better than any competitor.
Use a clear, well-lit image
Blurry or cluttered inputs confuse the model.
Describe motion explicitly
"Gentle swaying", "slow pan right", "hair blowing in wind".
Specify atmosphere
"Warm golden hour", "cold blue fog", "neon-lit rain".
Keep the subject centered
Especially important for multi-reference inputs.
Match audio to the image
For an ocean image: "gentle waves, distant seagulls".

Tips
Prompt Writing Tips for HappyHorse-1.0 (T2V & I2V)
Name the camera movement
"Slow zoom in", "tracking shot", "dolly forward" give the model clear direction.
Specify lighting
"Golden hour", "studio rim light", "neon night" set the scene instantly.
Add audio intent
"Ambient café noise", "dramatic orchestral swell", "wind through leaves".
Use style references
"Cinematic", "product commercial", "documentary", "anime".
Mention pace
"Slow, deliberate motion" vs "fast-cut energy" — pace shapes everything.
Avoid vague adjectives
"Beautiful" tells the model nothing. "Dramatic" + context does.
