Cinematic AI Video with Alibaba Happy Horse

Alibaba's Happy Horse generates cinematic videos from text prompts or animates a first-frame image into a full video. 1080p output, durations 3-15 seconds, support for both text-to-video and image-to-video workflows.

What makes Happy Horse different

Any duration from 3 to 15 seconds

Happy Horse lets you pick any whole-second duration between 3 and 15 seconds — not just the fixed 5-or-10 choice most video models offer. Because billing is per second, a 3-second sting costs a fraction of a full clip, which makes it practical to generate short cutaways, transitions, and loops without paying for footage you'll trim away.

Text to video and image to video in one node

Write a prompt of up to 2500 characters and Happy Horse invents the scene from scratch. Drop an optional first-frame image into the same node and it switches to image-to-video, animating your exact starting composition instead. One node on your Scenetra board covers both workflows — no swapping models when you decide to start from a still.

Cinematic 1080p output

Happy Horse renders at 720p or full 1080p, with five aspect ratios covering widescreen 16:9, vertical 9:16 for shorts and stories, square 1:1, and the 4:3 / 3:4 pair. Alibaba positioned the model squarely at cinematic look and camera movement, and the 1080p tier is where that shows.

A second mode for character consistency

The model on this page starts from text or a single first frame. When you need the same character, product, or style held consistent across shots, switch to Happy Horse Reference to Video — it accepts 1-9 reference images and lets you cite each one in the prompt as character1 through character9. Both modes sit side by side on the same Scenetra board.

Frequently asked questions

What is the Happy Horse video model?+

Happy Horse is Alibaba's AI video generation model. It creates cinematic clips from text prompts, or animates a first-frame image into a video, at 720p or 1080p and any duration from 3 to 15 seconds. On Scenetra it runs as a node in the visual workflow editor, alongside a separate Reference to Video mode for character consistency.

How can I use Happy Horse?+

The fastest way is in the browser: sign up for Scenetra, drop a Happy Horse node onto your board, write a prompt (optionally attach a first-frame image), and generate. No API key, no waitlist, no local GPU — Scenetra is web-based and works anywhere, and Happy Horse sits next to every other major video model on the same canvas.

Is Happy Horse free or paid?+

It's a paid model billed per second of video, but you can try it without paying: new Scenetra accounts start with free welcome credits and a 7-day trial, which covers your first generations. After that you pay per generation from your credit balance — there is no subscription gating the model and nothing to cancel.

How much does Happy Horse cost?+

On Scenetra, Happy Horse costs $0.14 per second at 720p and $0.28 per second at 1080p. A 5-second 1080p clip is $1.40; a 10-second one is $2.80. Because duration is adjustable per second from 3 to 15, you only pay for exactly the length you generate.

Is Happy Horse better than Seedance?+

They trade blows. Early comparisons generally rate Seedance 2.0 as the more established, more consistent model, while Happy Horse is newer and competes hard on cinematic look and price. On Scenetra you don't have to pick in advance — both are available on the same board, so you can run the same prompt through each and judge on your own footage.

Can Happy Horse do image to video?+

Yes. Attach a first-frame image to the node and Happy Horse animates from that exact composition, guided by your prompt. If you instead need one or more subjects held consistent across a scene, use the dedicated Reference to Video mode, which accepts 1-9 reference images.

What resolutions, durations, and aspect ratios does Happy Horse support?+

720p and 1080p output; any whole-second duration from 3 to 15 seconds; and aspect ratios 16:9, 9:16, 1:1, 4:3, and 3:4. Prompts can be up to 2500 characters.

Is Happy Horse open source?+

No — Alibaba has not released open weights for Happy Horse; it's available through hosted APIs. On Scenetra you can use it directly in the browser with no API setup, and compare it side by side with open-weight models like LTX-2 and Wan on the same board.
