HappyHorse is Alibaba's next-generation AI video model built on a native multimodal architecture. A single unified model covers four production scenarios — text-to-video, image-to-video, multi-image reference-to-video, and in-place video editing — with native audio-video synthesis, 720p/1080p output, and deep adaptation for advertising, e-commerce, short drama, and social creative content production.

Built from the ground up to co-generate audio and video, HappyHorse delivers synchronized motion and sound in a single pass — no post-production required.
Text-to-video, image-to-video, multi-image reference-to-video, and in-place video editing are handled by a single unified model with one consistent prompt style.
Bind up to 5 reference images to guide characters, scenes, and props. Mix and match references to compose multi-element shots with strong consistency.
Replace subjects, outfits, or even the entire visual style while preserving the original camera motion, lighting, and composition — ideal for localization and creative remixes.
Choose between 720p for rapid iteration or 1080p for final delivery. Crisp detail, clean compression, and ready-to-publish quality for short drama and ads.
HappyHorse is optimized for advertising, e-commerce, short drama, and social creatives — the content types that demand both polish and production speed.
See HappyHorse in action across all four scenes: text, image, multi-image reference, and video editing.
Generate video from pure text prompts with native audio
“A Pixar-style short about a nervous little traffic cone who dreams of being a finish line pylon at a major race. Other cones mock its ambitions. A construction worker accidentally places it at a marathon finish line. The cone's painted face shifts from terror to joy as runners pass. Confetti falls on its cone head. Other cones watch on TV, inspired. Audio: Traffic sounds becoming crowd cheers, inspirational swelling music.”
Duration: 5s
“8mm vintage film style, grainy texture, slight light leaks. A group of friends laughing and running on a beach in the 1970s. Sun-drenched colors, nostalgic atmosphere, handheld camera shaking slightly. Authentic retro look.”
Duration: 5s
“First-person POV (GoPro style), a high-speed mountain bike descent through a narrow, rocky forest trail. The camera vibrates with the bumps, trees rushing past in a blur. Intense sunlight filtering through the canopy. Adrenaline-pumping action, immersive sound of tires on gravel.”

Animate still images into motion with synchronized sound
“Tracking shot as the girl walks gracefully through the meadow. Her dress and hair flutter in the wind, and clouds drift slowly. Cinematic audio of soft footsteps on grass, rustling summer wind, and melodic bird calls.”
Duration: 5s
“First-person POV. The camera glides smoothly and continuously forward deep into the sci-fi corridor. Glowing neon lights pass by rapidly on both sides. Tiny glowing dust particles float in the illuminated air. Steady tracking shot, immersive atmosphere.”
Duration: 5s
“Time-lapse effect. The thick morning mist rolls and flows fluidly through the pine trees like a slow-moving river. The bright volumetric light rays shift their angle dynamically as the sun rises. Cinematic slow zoom in.”
Duration: 5s
Combine up to 5 reference images into a coherent scene
“The girl from Image 1 is jogging lightly through a sunlit forest. The glowing forest spirit from Image 2 playfully flies closely behind her like a small comet, leaving a faint luminous trail in the air. Golden light filters through the dense trees. Cinematic audio of soft, quick footsteps on grass, a gentle magical whoosh, and distant bird calls.”
Duration: 5s
“Place the cotton doll from Image 1 into the vintage room from Image 2. The doll sits on the wooden workbench, gently swinging its legs, looking around curiously. Keep the lighting of Image 2 and the plush texture of Image 1 strictly consistent.”
Duration: 5s
“The idol from Image 1 stands on the water stage from Image 2, directly in front of the giant glowing moon. The idol steps forward slowly, creating gentle ripples in the water, and raises the microphone to sing. The soft blue light from the moon reflects perfectly on the idol's outfit.”
Duration: 5s
Replace subjects, styles, or elements while keeping camera motion
“Replace the teenage boy in the video with SpongeBob SquarePants. He should retain his classic iconic look: a yellow rectangular sea sponge with large blue eyes, wearing a white collared shirt, red tie, and brown square pants. SpongeBob should be riding the skateboard naturally and performing the kickflip. Render him in a high-quality 3D realistic style to match the lighting and shadows of the real-world park background. Keep the original camera tracking and motion exactly the same.”
“Replace the grey hoodie and pants with the floral silk skirt from the reference image. The skirt should flow and sway naturally with the woman's walking and spinning motion. Keep her face, hair, and the living room background exactly the same.”
“Transform the entire video into a vibrant Lego world. The person, the desk, and every object in the room should be constructed from high-quality plastic Lego bricks. Keep the original waving motion and spatial layout perfectly. The lighting should be bright and clean, like a professional Lego toy commercial.”
