HappyHorse 1.0 API Routes for Video Generation and Editing

Compare four HappyHorse 1.0 modalities by input, output, resolution, duration, and production use.

ModalityDescription
HappyHorse 1.0 T2V API (Text To Video)Turn text prompts into 720P or 1080P videos lasting from 3 to 15 seconds, with flexible aspect ratios for different delivery formats. Use this endpoint for storyboards, promotional clips, and visual concepts created without source footage.
HappyHorse 1.0 I2V API (Image To Video)A first-frame image becomes a 720P or 1080P video, while an optional prompt provides additional guidance for the animation. Durations from 3 to 15 seconds suit product visuals, character shots, and social content built from existing artwork.
HappyHorse 1.0 Reference-to-Video APIWhen visual guidance matters, supply one to nine reference images with a text prompt to generate a 720P or 1080P video. Flexible aspect ratios and 3 to 15 second durations support character-driven scenes, branded assets, and reference-led creative production.
HappyHorse 1.0 Video Edit APIRefine an input video through text instructions, with optional reference images available to guide the requested changes. The endpoint produces 720P or 1080P output for restyling footage, revising scene elements, and adapting existing video assets.

Inside the HappyHorse API: Unified Video and Audio in One Pass

From Arena-topping cinematic quality to native multilingual sound, the HappyHorse API combines unified multimodal generation, lifelike motion, image animation, and an asynchronous workflow behind one pay-as-you-go endpoint.

Cinematic Quality from the HappyHorse API

HappyHorse holds the top spot on the Artificial Analysis Video Arena for both text-to-video and image-to-video, judged by blind human preference. That ranking translates into footage with convincing detail, lighting, and cinematic composition.

Lip Sync Across Seven Languages

Native lip sync spans Mandarin, Cantonese, English, Japanese, Korean, German, and French, with dialogue and Foley generated alongside the video. Localized campaigns no longer need a separate dubbing or sound design pass.

Unified Multimodal Core of the HappyHorse API

Text, image, video, and audio tokens flow through one unified Transformer sequence instead of a chained multi-stage pipeline. Your integration stays simple because every generation mode shares the same underlying architecture.

Motion That Obeys Real-World Physics

When subjects run, collide, or interact, the physics stays believable, a strength behind HappyHorse leading blind image-to-video comparisons on the Video Arena. Sports clips, chase scenes, and dance sequences keep their weight on screen.

Still Photos to Living Scenes with the HappyHorse API

Feed one photograph to the image-to-video endpoint and watch it become fluid 1080p motion while subject identity stays intact. Product shots, portraits, and concept art all animate without losing their look.

Fast Turnaround, Asynchronous by Design

An asynchronous task workflow keeps generation moving: submit a prompt, poll for status, and retrieve the finished clip without blocking your application. Rapid iteration cycles fit tight campaign and prototyping deadlines.

HappyHorse vs Other Models - One Prompt

The same prompt, generated by HappyHorse and other leading video models: cinematic short film and high-end commercial film

Prompt

Create a 10-second cinematic short film about a street musician and a child meeting in a sunny city square. Scene 1, 0-2s: Wide establishing shot of a bright European-style city square in the late afternoon. A street musician sits near a fountain, playing an acoustic guitar. Warm sunlight, soft shadows, pigeons moving in the background, natural city ambience. Scene 2, 2-5s: Medium tracking shot as a young child walks toward the musician while holding a small red balloon. The musician continues playing guitar. The child’s steps, the guitar rhythm, and the ambient crowd sound should feel synchronized and natural. Scene 3, 5-8s: Close two-shot: the musician smiles and slightly changes the melody as the child stops beside him. The child gently taps the balloon in rhythm with the music. Keep both characters’ faces, clothing, body proportions, and spatial positions consistent. Scene 4, 8-10s: Final cinematic pullback shot: the musician keeps playing, the child laughs, pigeons fly across the square, and the fountain sparkles in the sunlight. The music and city ambience fade naturally. Requirements: - Maintain consistent identity, clothing, and proportions for both characters across all shots - Keep the red balloon, guitar, fountain, and city square layout consistent - Use readable cinematic camera control: wide shot, tracking shot, close two-shot, final pullback - Synchronize audio with action: acoustic guitar, footsteps, child laughter, pigeons, fountain, city ambience - Natural human motion, stable hands, realistic guitar-playing movement - No warped faces, no changing character outfits, no disappearing balloon or guitar - Warm cinematic realism, polished short-film look, 1080p

Prompt

Create a 10-second cinematic lifestyle commercial for a smart home coffee machine. Scene 1, 0-2s: Wide shot of a bright modern kitchen in the morning. A smart coffee machine sits on a clean countertop beside a white ceramic cup. Soft sunlight enters through the window, warm and natural. Scene 2, 2-5s: Medium shot of a young professional entering the kitchen and tapping the touchscreen on the coffee machine. The screen lights up smoothly. Add a soft button tap sound, quiet machine startup sound, and subtle morning ambience. Scene 3, 5-8s: Close-up of coffee pouring into the cup. Steam rises naturally, the crema forms on the surface, and the machine remains the exact same design, size, color, touchscreen position, and material. The pouring sound should match the liquid motion. Scene 4, 8-10s: Final hero shot: the person lifts the cup and smiles while the coffee machine stays sharp in the background. Camera slowly pulls back, clean premium home appliance commercial look. Requirements: - Maintain the exact same coffee machine design across all shots - Keep the kitchen layout, countertop, cup, lighting, and product scale consistent - Use readable cinematic camera control: wide shot, medium interaction shot, close-up, final pullback - Synchronize audio with action: button tap, machine startup, coffee pouring, soft morning ambience - Natural hand movement, realistic liquid physics, stable product geometry - No warped hands, no changing touchscreen position, no inconsistent product details - Bright cinematic realism, high-end lifestyle commercial style, 1080p

HappyHorse 1.0 API FAQ: Access, Inputs, and Limits

HappyHorse 1.0 is Alibaba's AI video model family for generating or editing short clips from text, images, reference images, or existing footage. Atlas Cloud provides four pay-as-you-go endpoints with 720P and 1080P output.

Start from a prompt with text-to-video, animate a first-frame image, or guide a new clip with one to nine reference images. For existing footage, the video-edit endpoint accepts text instructions and optional reference images.

On Atlas Cloud, both versions provide text-to-video, image-to-video, and reference-to-video endpoints. HappyHorse 1.0 also includes a video-edit endpoint that transforms existing footage using text instructions and optional reference images.

Create an Atlas Cloud account, generate an API key in the dashboard, and send the required inputs with the appropriate model ID to the video generation endpoint. Keep the returned prediction ID so your application can retrieve the completed result.

Requests run asynchronously, so the initial response returns a prediction ID instead of holding the connection open until generation finishes. Poll the prediction endpoint until the status is completed, succeeded, or failed, then read the output URL from a successful response.

Text-to-video and reference-to-video can render 720P or 1080P clips lasting from 3 to 15 seconds. Available aspect ratios are 16:9, 9:16, 1:1, 4:3, and 3:4, while image-to-video uses an uploaded image as the first frame.

Provide one to nine image URLs with a prompt explaining how the supplied subjects, objects, or visual cues should appear and move. Accepted formats are JPEG, JPG, PNG, and WEBP, with each image limited to 20 MB and at least 400 pixels on its shorter side.

Each HappyHorse 1.0 endpoint has a verified standard base price of $0.14 per generation on Atlas Cloud. Billing is pay-as-you-go, with no subscription required to access the text, image, reference, or editing workflows.

Plan around a 15-second maximum for text-to-video, image-to-video, and reference-to-video generations. Community tests report that fast or complex multi-subject motion can produce inconsistent frames, so review outputs and allow for retries before production use.
