From any input to a finished video in four simple steps
Choose T2V, I2V, R2V or EDIT based on whether you have a prompt, first frame, reference images, or a source video.
Write a detailed Happy Horse prompt (up to 2500 chars) describing the scene, action, lighting and camera.
Select resolution (720P/1080P), exact duration (3–15s) and aspect ratio if applicable.
Happy Horse renders the clip; preview, download MP4 and reuse the seed to iterate.
Built on Happy Horse 1.0, designed for fast iteration and professional cinematic output
T2V, I2V, R2V and EDIT all run on the same Happy Horse 1.0 model — switch by changing inputs, not models.
Pick any integer second count from 3 to 15 in Happy Horse. No more wasted footage from fixed presets.
Happy Horse renders directly at 1080P with strong temporal coherence, or use 720P for rapid drafting.
Happy Horse R2V mode mixes 1–9 reference images so characters, props and style stay on brand across shots.
Happy Horse EDIT mode reimagines an existing video and lets you keep the original audio or auto-generate a new one.
Pass a seed to lock the Happy Horse result, then iterate prompts safely without losing the look you found.
Trusted by video creators, marketers and educators who need flexible duration and professional-quality AI video generation
Happy Horse is my go-to AI video tool now. The ability to pick exactly 7 seconds — not 5 or 10 — fits my editing rhythm perfectly. I've tried Kling and Sora, and Happy Horse's custom duration is a genuine differentiator.

I sketched a first-frame concept and Happy Horse turned it into a 12-second I2V explainer in minutes. The output was surprisingly faithful to my drawing. Happy Horse is perfect for educators.
