What Makes It Different
Built for creators, directors, and developers who demand more from AI video generation — precision inputs, cinematic outputs, and zero compromises.
Text, Image, Video & Audio
Accept up to 9 images, 3 video clips, and 3 audio files in a single generation request. Reference each asset in your prompt with [Image1], [Video1], or [Audio1] tags — giving you multi-layered creative control no other AI video generator can match.
One Pass. Full Production.
Generate synchronized video and audio in a single pass — no separate post-production. The model learns rhythm, atmosphere, and sound design directly from your reference audio, delivering production-ready output from a single API call.
Beyond Single Clips
Direct full multi-shot sequences with tracking shots, aerial views, and POV angles — all stitched into one coherent scene. Character identity, lighting, and environment stay consistent across every cut for true cinematic continuity.
Pan, Tilt, Zoom, Roll & Dolly
Precision control over Pan, Tilt, Zoom, Roll, and Dolly Zoom. Whether you need a slow push-in or a dramatic crane shot, the model executes your camera direction with filmmaking accuracy — no more random motion from AI generation.
One Photo. Infinite Angles.
Upload a single reference photo and HappyHorse 1.5 maintains facial features, clothing, and character style throughout the entire video — even through 360° head turns and dramatic lighting shifts. Built for branded content, ads, and narrative film.
Cloth, Fluid, Hair & Collisions
Renders cloth, fluid, hair, smoke, and complex object collisions with physically accurate motion. Sports, dance, and action scenes look indistinguishable from real footage — at over 10× the generation speed of previous versions.
Use Cases
From solo creators to enterprise studios, HappyHorse 1.5 fits every workflow — one API, infinite creative directions.
Generate on-brand product videos at scale with consistent characters, synchronized audio, and zero studio overhead. Cut campaign production time from weeks to hours.

Quick Start
From sign-up to your first generated video in under 60 seconds.
Sign up free in seconds. No credit card required — free credits included on registration.
Free to startCopy your key from the Atlas Cloud dashboard. Add it as Authorization: Bearer $ATLASCLOUD_API_KEY in every request.
Send your prompt to the generateVideo endpoint. You'll receive a prediction_id in data.id immediately — generation runs async.
GET /prediction/{id} every 2s until data.status is succeeded. Your video URL is at data.outputs[0].
