Happy Horse 1.0 AI Video Generator
One model, four workflows — generate from text, images, or reference clips, and edit existing footage with a prompt.
Happy Horse 1.0 is the utility player of AutoDirector's model lineup: it's the only model on the platform that covers all four workflows — text to video, image to video, reference to video, and video editing — in a single model. Instead of learning a different tool for each job, you keep one prompting style and switch modes as the task changes.
The standout capability is video editing: upload existing footage and describe the change — swap the background, restyle the scene, alter the weather — and Happy Horse re-renders the clip with your edit applied. Combined with reference to video, it makes Happy Horse the strongest choice for working with footage you already have rather than starting from a blank prompt.
Generations run 3 to 15 seconds at 720P or 1080P in five aspect ratios. Pricing follows the flagship tier: 10 credits per second at 720P for text and image modes, with reference and editing modes priced higher for the heavier computation.

Reference to video
Carry motion or subjects from an existing clip into a new generation for consistent characters and repeatable moves.
Flexible 3–15s durations
Any whole-second length, priced per second — from a 3-second loop to a full 15-second sequence.
Five aspect ratios
Landscape, vertical, square, and classic 4:3 / 3:4 — matched to feeds, ads, and legacy formats.
Works with your footage
Built for editing and remixing what you already shot — not just generating from scratch.
