HappyHorse 1.0
Alibaba HappyHorse 1.0 is built for cinematic short video generation. This page supports both text-led drafting and first-frame image animation: use text-to-video when you want to explore a scene from a prompt, and image-to-video when you already have a subject, composition, or visual style to preserve.
Start
Choose text drafting or first-frame animation
Write the shot first
For text-to-video, describe the subject, action, setting, camera movement, and frame shape before adding style words.
Pick a clear first frame
For image-to-video, use one clean reference image with a visible subject and complete composition, then describe what should move next.
Lock parameters after a good direction
Once a result is close, record the seed, resolution, duration, prompt, and reference image version so you can reproduce or iterate deliberately.
Decision
How parameters change the result
Aspect ratio
Impact: Changes the output frame for text-to-video and affects horizontal, vertical, or square composition.
Recommendation: Choose by channel for text-to-video: 16:9 for landscape, 9:16 for vertical, and 1:1 for square. For image-to-video, let the first-frame image drive the composition.
image
Impact: Image-to-video animates one first-frame image, so the subject, composition, and base visual style come from that image.
Recommendation: Use a clear JPEG, PNG, BMP, or WEBP with the subject intact. Keep the image aspect ratio between 1:2.5 and 2.5:1.
resolution
Impact: Resolution changes estimated credits. 1080p currently costs about twice as much as 720p.
Recommendation: Use 720p while testing prompt direction or motion. Move to 1080p once the scene is close.
duration (3-15s)
Impact: Duration scales estimated credits and determines how much action the clip can hold.
Recommendation: Start short to validate rhythm and subject behavior, then extend only after the direction is working.
seed
Impact: Seed helps reproduce or lightly vary a result direction.
Recommendation: Leave it open while exploring. Save a seed only after you see a result worth reproducing.
Cost
Cost and runtime expectations
| Workflow | Parameters | Estimated credits |
|---|---|---|
| Text to video | 720p or 1080p · 3-15s | Resolution × duration |
| Image to video | 720p or 1080p · 3-15s | Same dynamic estimate |
| Example | 720p · 5s | 210 |
| Example | 1080p · 10s | 840 |
Method
How to judge before using it
Start with the goal: If you are testing prompt, frame, or duration, start with text-to-video at 720p and a short duration. If you already have a character, product, scene, or key frame, start with image-to-video.
Then inspect the result: After generation, check subject stability, motion, composition, and key details before deciding whether to iterate or export.
- • Write the subject, action, camera movement, and frame clearly.
- • For image-to-video, confirm the first frame is clear and uncropped.
- • For comparisons, change the prompt slightly or adjust the seed.
- • Save the working parameters before changing resolution or duration.
FAQ
FAQ
- Is HappyHorse 1.0 suitable for final videos?
- That depends on the generated clip, your project bar, and whether you plan to edit further. Treat each output as something to review against your own acceptance criteria.
- Should I start with 720p or 1080p?
- Start with 720p while testing prompt, framing, and duration. 1080p currently costs about twice as much, so it is better to use after the direction is close.
- How is HappyHorse 1.0 pricing estimated?
- Both text-to-video and image-to-video use dynamic estimates by resolution and duration: 720p is about $0.14 per second, and 1080p is about $0.28 per second. Credits are converted from the current dollar estimate and rounded up.
- When should I use image-to-video?
- Use image-to-video when you already have a character, product, scene, or key composition to preserve. The image provides the visual base while the prompt guides motion, camera, and mood.
- When should I compare Kling, Veo, or Seedance instead?
- If your task needs a different workflow shape, such as stronger reference handling, video editing, audio, or expansion, compare those models with the same prompt and acceptance criteria.
