Generate production-ready video from any idea — with physics-accurate motion, native audio, and multilingual dialogue built in.
Happy Horse 1.0 generates video frames and a fully synchronized audio track — dialogue, ambient sound, and Foley effects — in a single forward pass. No separate dubbing pipeline. No post-production audio sync.
Wide-angle low tracking shot, camera racing ahead of a lone man sprinting at full speed down a crowded city street. He wears a dark jacket, face desperate and sweating. Behind him a mob of over a hundred people — police officers, civilians, suits — floods the street in chaotic pursuit, shouting. Slow-motion cinematic shot, 120fps playback feel. The running man crashes full-speed into a street fruit stall — wooden crates explode outward, oranges, apples erupt into the air in every direction, tumbling in graceful arcs. Vendor dives aside in panic. Flying fruit fills the frame mid-air.
Happy Horse 1.0 supports phoneme-level lip synchronization across English, Mandarin, Cantonese, Japanese, Korean, German, and French — useful for international campaigns, localization work, and multilingual storytelling.
Rear-view handheld, slight sway. A broad-shouldered Italian man in his 40s, dark overcoat, stands before a warm wooden front door. He exhales slowly, shoulders drop. Then straightens, sets his jaw, forces a quiet smile, reaches into pocket for keys. Extreme close-up on a weathered brass door lock. A hand inserts a key and turns it. Door opens, warm interior light floods in. A 6-year-old girl throws herself at him arms wide, a golden retriever launches forward barking, tail wagging. He catches the girl, lifts her, breaks into a wide genuine smile. Background: a glowing Christmas tree and his wife watching.
Happy Horse 1.0 produces coherent multi-scene sequences from a single prompt — complete with natural camera cuts, persistent character identity, and smooth visual transitions. Tell a full story, not just a moment.
High-angle wide shot of a clay miniature town. Packed two-story clay buildings line a cobblestone alley converging toward a warm sunset. Tilt-shift diorama lens effect. Friendly plump white ghosts with dot eyes scattered through the street. A girl in white dress and red cap pushes a delivery cart down the alley. Warm amber and dusty rose sky. Three quick medium shots in the same clay world: a round white ghost splicing overhead wires with focused tiny hands; a ghost cheerfully serving customers at a wooden grocery stall; a ghost sweeping cobblestones with an oversized straw broom. The girl pushes her wooden cart past clay storefronts, a tiny ghost hitching a ride among the packages.
Powered by DMD-2 distillation and MagiCompiler accelerated inference, Happy Horse 1.0 renders full 1080p video in approximately 38 seconds on H100 — 30% faster than Seedance 1.5 Pro and 29% faster than Kling 2.1.
Extreme close-up of a man's face, head-on. Mid-40s, mustard-yellow athletic shirt, dark wood-paneled elevator background with brass trim. Eyes wide, jaw open, brow furrowed — raw panic. Harsh overhead light. Camera holds still for 2 seconds. Camera orbits the man continuously inside the elevator, completing 540° total — ending behind him facing the closed doors. Smooth gimbal motion, claustrophobic. Elevator doors open to a dim corridor. Man sprints out immediately. Camera whips around and tracks alongside him running. Flickering corridor lights. No cuts, one continuous unbroken take.
