Happy Horse AI Video Generator

Happy Horse is Alibaba’s short-clip video family. The first public line is Happy Horse 1.0: text-to-video, image-to-video and reference-to-video, 3 to 15 seconds, 720p or 1080p, with native synced audio. Happy Horse 1.1 is the later SKU. This site does not run either.

01 — Capabilities

Sound in the same 3–15 second pass

Numbers below are from Alibaba and aggregator model cards for Happy Horse 1.0. Do not read Wan 3.0’s 30-second window onto this family.

01
3 to 15 seconds
Clip length steps by one second from 3 through 15. That is the documented ceiling on 1.0 generate. It is not a 30-second model.
02
720p or 1080p, with native audio
Happy Horse 1.0 generates picture and sound together: dialogue, lip sync and scene audio in one pass. Prompts in other languages are used for spoken output. There is no 4K generate listed on this line.
03
Text, a still, or references
Start from a prompt, animate one first-frame still, or use reference-to-video. Video editing on aggregator cards is labeled Happy Horse 1.0: the output follows the source, billed up to 15 seconds.
04
1.1 is a later SKU
Happy Horse 1.1 is documented as a quality upgrade over 1.0, with a 1–9 image reference path. That SKU has its own page. This page is the family and the 1.0 generate.

02 — Prompt to output

Prompts that match the clips above

Each prompt describes the picture on its card. “Use this prompt” sends that text to Create. The generator on this page runs Seedance 2.5, not Happy Horse.

01 · Portrait
PromptClose-up of a young man with curly hair in a grey knit sweater, soft window light. He glances away, then smiles. Slow push-in, shallow depth of field.
02 · Product
PromptA white leather sneaker on a pale grey studio backdrop, soft diffused light. The camera orbits slowly. Stitching stays sharp, the look stays minimal.
03 · Street
PromptA slow dolly down a cobblestone lane in an old European village. Climbing roses on stone walls, café tables in morning sun, a few people walking in the distance.
04 · Character
PromptA young woman with shoulder-length brown hair in an olive t-shirt, late-afternoon gold light. She turns her head and looks off. Breeze in her hair, a handheld feel.

03 — Where it fits

Jobs that need a voiced 15-second clip

Pick Happy Horse when the line and the mouth have to land together. Wan 3.0 is Alibaba’s longer video series — that is another page.

A talking-head beat
3–15 seconds is enough for a look, a line and a small camera move. Native audio is the point of this family, not a mute generate you score later.
Animate a product still
Image-to-video takes one first frame. Keep the prompt to what moves. The documented generate size is 720p or 1080p.
Keep a face across a short scene
Reference-to-video is on the 1.0 card. For the later 1–9 image stack, use the Happy Horse 1.1 page. Neither path runs here.
Rewrite a clip you already have
Aggregator cards put video editing on Happy Horse 1.0. Output follows the source, capped at 15 seconds. That is an edit, not a blank 15-second generate.

04 — Verdict

What the Happy Horse 1.0 cards actually list

Native synced audio and lip sync
Text-to-video, image-to-video and reference-to-video

Happy Horse 1.1 is a separate SKU, not this generate
Happy Horse is not available on ImgToVid

05 — Side by side

Happy Horse, Wan 3.0 and Kling 3.0

All three can put sound with the picture. Length and who makes them are where they split.

Developer	Alibaba	Alibaba	Kuaishou
Single clip	3–15 seconds	4–30 seconds on this site	3–15 seconds
Picture	720p or 1080p	480p–1080p, default 720p	720p, 1080p, 4K listed
Sound	Native, with lip sync	Switch, default on	Native; five languages plus dialects
Start from	Text, still, references; 1.0 edit	Text, still, frames, references	Text, still, frames, elements

06 — How it works

Draft the shot on ImgToVid

Step 1
Write a 3–15 second voiced beat
If you wanted Happy Horse’s native audio or a first-frame still, put the line and the move in the prompt. Happy Horse will not be the model that runs it.
Step 2
Use the generator on this page
It runs Seedance 2.5, because Happy Horse is not offered here. The prompt and the settings carry into Create.
Step 3
Generate in Create
Membership and credits are checked there. Coming back to this page does not switch the model over to Happy Horse.

07 — FAQ

Happy Horse, in plain terms

What is Happy Horse?

Happy Horse is Alibaba’s short-clip video family. Happy Horse 1.0 is the first public generate: text-to-video, image-to-video and reference-to-video, 3–15 seconds, 720p or 1080p, with native audio. Happy Horse 1.1 is the later SKU.

How long is a Happy Horse clip?

3 to 15 seconds. That is the documented generate window on 1.0 and 1.1. It is not Wan 3.0’s 4–30 seconds.

Does Happy Horse generate audio?

Yes. 1.0 cards describe synced speech, lip sync and scene audio in the same pass. Prompts in other languages are used for spoken output.

Happy Horse or Happy Horse 1.1?

This page is the family and 1.0. 1.1 is documented as a quality upgrade, including a 1–9 image reference path — that is the Happy Horse 1.1 page. Neither runs on ImgToVid.

Can I generate Happy Horse on ImgToVid?

No. The generator on this page runs Seedance 2.5 so you can draft a shot. Happy Horse is marked coming soon.

Can I use the results commercially?

Commercial use of anything you generate on ImgToVid depends on your plan. Check Pricing and our Terms before you publish, and make sure prompts and uploads do not infringe someone else’s rights.
