Happy Horse Edit 1080p API for AI Video Editing

Overview

Happy Horse Edit 1080p is a prompt-guided AI video editing model available through UniAll AI. The public model id is `happy-horse-edit-1080p`. It is designed for editing or generating short videos from source video, reference images, and text instructions, with output resolution options including 720p and 1080p.

The model is useful when teams need high-resolution short-form video assets, product clips, ad variations, social media cuts, visual storyboards, or automated creative workflows. It supports asynchronous video generation, so applications can submit a job, poll or receive status updates, and retrieve the result when processing is complete.

What It Can Do

Happy Horse Edit 1080p supports video-oriented workflows such as:

Video-to-video editing from a source video URL
Image-to-video generation using 1-5 reference images
Reference-media-driven video generation
Prompt-based changes to motion, style, scene mood, and content direction
Short video outputs from 3 to 15 seconds
720p or 1080p output resolution

The model processes short clips and is best suited for concise video edits rather than long-form production. For video editing mode, provide a source video and a clear prompt describing what should change or be preserved.

Target Users

Happy Horse Edit 1080p is a good fit for developers, creative tool builders, marketing teams, ecommerce operators, agencies, and platforms that need AI video editing through an API. Typical use cases include product showcase videos, short ad creatives, vertical social clips, campaign variants, video enhancement workflows, and internal content automation.

For enterprise or platform use, UniAll AI provides a unified API layer so teams can integrate the model into dashboards, batch workflows, reseller systems, or customer-facing generation products without building separate model-specific infrastructure.

API Usage

The API uses an asynchronous video generation endpoint:

`POST /v1/videos/generations`

Example request body:

```json { "model": "happy-horse-edit-1080p", "generation_mode": "video_to_video", "prompt": "Make the product video feel more cinematic with soft studio lighting and smooth camera motion.", "duration": 5, "video_url": "https://example.com/source.mp4", "video_count": 1, "resolution": "1080p" } ```

Key parameters include:

`model`: use `happy-horse-edit-1080p`
`generation_mode`: `video_to_video`, `image_to_video`, or `reference_media_to_video`
`prompt`: required text instruction
`duration`: 3-15 seconds
`video_url`: source video for video editing mode
`reference_image_urls`: 1-5 images for image-to-video workflows
`resolution`: `720p` or `1080p`
`video_count`: fixed at 1 video per generation

Supported upload formats include MP4, QuickTime, and WebM for video input, plus PNG, JPEG, and WebP for reference images.

Pricing Angle

Happy Horse Edit 1080p is billed per second. In the listed UniAll AI user pricing profile, 1080p generation is priced at $0.3808 per second, while the 720p variant is priced at $0.1904 per second. Actual cost depends on selected duration and resolution.

For example, a 5-second 1080p job would be estimated from the per-second 1080p rate. Failed generations are refund eligible according to the model configuration, while automatic retry is not enabled by default.

Practical Guidance

For best results, keep prompts specific and production-oriented. Mention the desired subject behavior, camera motion, visual style, lighting, and what should remain unchanged from the source. When using reference images, provide clean, relevant images that match the desired identity, product, or scene direction.

Choose 1080p when output quality matters for product pages, ads, or polished social assets. Choose 720p for lower-cost drafts, iteration, and internal previews.
