02
Image to Video
Upload or pass one image_urls item to animate a first frame. Prompt is optional, so apps can either preserve the source composition or add motion and camera direction.
03
Reference to Video
Send reference_image_urls with a required prompt to guide subject, style, or scene continuity. PoYo supports up to 9 reference images and keeps them mutually exclusive with image_urls.
Key Features of Happy Horse 1.1 API
Happy Horse 1.1 supports text-to-video, first-frame image-to-video, and reference-guided video generation with 720p or 1080p short-form output. PoYo keeps the public API focused on the controls available in the playground.
01
Prompted Scenes with Motion and Audio
Use text-to-video when your product needs a complete generated scene from a written prompt. Happy Horse 1.1 is designed for smoother motion, improved instruction following, and generated clips with native audio and lip-sync support, while PoYo keeps the request shape simple for API integration.
- Prompt-only text-to-video
- 3-15 second clips
- 720p or 1080p output
02
First-Frame Animation from One Image
Use image-to-video when the opening frame matters. PoYo maps the first image_urls item to the provider first-frame input, with an optional prompt for camera movement, action, lighting, or scene style.
- Exactly one image_urls item
- Optional motion prompt
- No separate audio or edit controls required
03
Reference-Guided Video with Up to 9 Images
Use reference-to-video when you want visual guidance from multiple images without treating one image as the first frame. This mode is useful for subject continuity, visual style direction, and reference-based scene generation.
- 1-9 reference_image_urls
- Prompt required
- Cannot be combined with image_urls

Frequently Asked Questions about Happy Horse 1.1 API
Which model ID should I use?
Use happy-horse-1.1. The same public model ID supports text-to-video, image-to-video, and reference-to-video on PoYo.
How does PoYo choose the video mode?
If image_urls has one item and reference_image_urls is empty, PoYo uses image-to-video. If reference_image_urls has items and image_urls is empty, PoYo uses reference-to-video. If both are empty, PoYo uses text-to-video.
Can I send image_urls and reference_image_urls together?
No. image_urls and reference_image_urls are mutually exclusive. Use image_urls for a single first-frame image, or reference_image_urls for reference-guided generation.
Is prompt required?
Prompt is required for text-to-video and reference-to-video. Prompt is optional for image-to-video.
