Happy Horse 1080p API for AI Video Generation

What is Happy Horse 1080p?

Happy Horse 1080p is a high-definition video generation model available through UniAll AI. The public model id is `happy-horse-1080p`. It supports asynchronous AI video generation for teams that need short-form creative assets, product videos, ad concepts, storyboards, and social media clips.

The model supports three main workflows:

**Text to video**: generate a video from a written prompt.
**Image to video**: animate or extend a single reference image.
**Reference image to video**: use multiple reference images to guide visual style, subject consistency, or scene direction.

Best use cases

Happy Horse 1080p is a good fit when output clarity matters and the video is intended for review, publishing, or downstream editing. Common use cases include:

1080p short video assets for social campaigns
Product reveal and ecommerce videos
Advertising concept clips
Vertical 9:16 videos for mobile feeds
Horizontal 16:9 videos for landing pages or presentations
Storyboard shots for creative teams
Automated video generation inside internal tools or SaaS workflows

Supported parameters

The API uses the `/v1/videos/generations` endpoint with asynchronous generation.

Key parameters include:

| Parameter | Type | Notes | |---|---:|---| | `model` | string | Use `happy-horse-1080p` | | `prompt` | string | Required for all modes | | `generation_mode` | string | Examples: `text_to_video`, `reference_image_to_video`, `reference_media_to_video` | | `duration` | integer | 3 to 15 seconds | | `resolution` | string | `720p` or `1080p`; use `1080p` for this model variant | | `aspect_ratio` | string | `16:9`, `9:16`, `1:1`, `4:3`, or `3:4` | | `image_url` | string | Optional single reference image for image-to-video | | `reference_image_urls` | array | Optional 1–9 reference images | | `video_count` | integer | Fixed at 1 video per generation |

Example API request

```bash curl -X POST "https://api.uniall.ai/v1/videos/generations" \ -H "Authorization: Bearer $UNIALL_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "model": "happy-horse-1080p", "generation_mode": "text_to_video", "prompt": "A cinematic product reveal of a premium running shoe, soft studio lighting, smooth camera push-in, realistic motion.", "duration": 5, "resolution": "1080p", "aspect_ratio": "16:9", "video_count": 1 }' ```

For image-guided generation, add `image_url` or `reference_image_urls` depending on the selected mode.

Pricing and billing angle

Happy Horse 1080p is billed per generated second. On UniAll AI, the listed user price for the 1080p variant is **$0.1904 per second**. A 5-second 1080p generation is therefore estimated at about **$0.952** before any account-specific adjustments.

A 720p variant is also available at a lower per-second rate, which can be useful for drafts, testing, and high-volume iteration before final 1080p rendering.

Failed generations are eligible for refund handling according to the platform policy shown for the model. The model is asynchronous, so production integrations should submit a job, poll or listen for completion, and store the returned video URL once ready.

Who should use it?

Happy Horse 1080p is useful for developers, agencies, ecommerce teams, creator-tool builders, and enterprises that want programmable video generation without building model infrastructure. It is especially practical for workflows where prompts, product data, or uploaded reference images are converted into repeatable video assets through an API.

Integration tips

Use clear prompts with subject, motion, camera direction, lighting, and style.
Choose `9:16` for mobile-first short video and `16:9` for web or presentation use.
Start with shorter durations for iteration, then render longer clips when the direction is approved.
Use reference images when brand, product, or character consistency matters.
Treat video generation as an async job in your application architecture.
