One Model for Video, Sound, and Speech
Native Audio and Multilingual Lip-Sync
Most AI video tools give you a silent clip and leave the sound to you. Happy Horse 1.1 generates the video and its audio together in a single pass, and when a character speaks, their lips match the words. Lip-sync works across multiple languages, so talking-head explainers, dialogue scenes, and ads feel finished the moment they render.
Text, Image, and Reference to Video
Start however you like. Write a prompt for text-to-video, animate a still photo with image-to-video, or upload reference images so the model locks onto a specific character or product. Reference-to-video keeps the same face, outfit, or item recognizable from one clip to the next.
Consistent Characters With Up to 9 Reference Images
Eliminate character morphing. Add up to 9 reference images and Happy Horse 1.1 holds the subject's face, outfit, and product details steady across the whole clip, so your hero looks like the same person in every shot instead of drifting between frames.
Smoother Motion, Stronger Prompt Following
As Alibaba's #1-ranked video model, version 1.1 is a clear step up from 1.0: more fluid movement, fewer warped frames, and tighter adherence to what you actually asked for, even on longer prompts.
Cinematic Camera Control
Direct the shot with plain language. Ask for a slow pan, a tilt, a zoom, or a tracking move, and you get the framing of a real camera operator without any equipment.
