HappyHorse — Make a new video or rework your own, with one model.

HappyHorse is Alibaba’s video model, unveiled in April 2026, and it covers four ways of working: from text, from one image, from several reference images, or from a video you want to change. On Deepnia it makes 3–15 second clips in 720p or 1080p, with sound, and reworks footage you upload, for example to restyle it or swap an object.

What HappyHorse does best

Four ways to create in one model

With no media, HappyHorse starts from your text; with one image, it animates it; with 2 to 9 images, it combines them; with a video, it edits it. On Deepnia the mode simply follows what you add.

Up to 9 reference images

Bring a person, a product and a setting from different images into one video, for an ad or a product page. Alibaba aims HappyHorse at advertising, ecommerce, short-form video and social media marketing.

Edit a video you already have

Add a video and up to 5 reference images, then describe the change. Alibaba lists style transfer, replacing an element and inserting a subject: swap a shop sign or a product, for example, without a reshoot.

Sound, created or kept

With Auto, the default, HappyHorse creates the video’s sound. When you edit your own video, pick Original under “Source audio” to keep its voices, music and ambience.

Several shots in one video

Alibaba says HappyHorse can cut between several shots while keeping characters stable across the cuts, which suits short dramas. Describe them in your prompt, numbered (Shot 1, Shot 2…).

Vertical to widescreen, in 720p or 1080p

Choose 9:16, 1:1, 16:9, 4:3 or 3:4 for text or several images; from a single image or a video, HappyHorse keeps the source’s aspect ratio. Test in 720p, then switch to 1080p for the final cut.

How to use HappyHorse on Deepnia

  1. Open the video tool

    The “Try HappyHorse” button opens Deepnia’s video tool with the model already selected.

  2. Add your media, or none

    Add 1 image to animate or 2 to 9 images to combine, or add a video to edit along with up to 5 images. With no media, the video starts from your text.

  3. Describe the scene or the change

    The prompt is required, up to 5,000 characters: scene, action and camera for a new video, the change you want for an edit.

  4. Set it up and generate

    Choose the length (3–15 s), resolution and aspect ratio; when editing, the length follows your video and the “Source audio” setting offers Auto or Original. Check the cost shown, then create.

Tips for better results

  1. With several images, refer to each one by its position (“the woman from the first image”, “the bag from the third image”) and say what it brings: a person, a product or a setting.
  2. When editing, say what changes and what must stay the same: movements, framing, faces, lighting.
  3. Keep the source video to 15 seconds or less: according to Alibaba, it is the first 15 seconds that get edited.
  4. To animate a photo, describe the motion and the camera rather than what is already visible: the video keeps the image’s framing and aspect ratio.
  5. To chain several shots, number them in the prompt (Shot 1, Shot 2…) and give each one its framing.
  6. Test the idea in 720p, then run it again in 1080p for the final cut.

Good to know

  • To tell a longer story, create several 15-second clips and join them in your editor.
  • Pick 9:16 for Reels, TikTok and Shorts, and 16:9 for YouTube and the web; from an image or a video, HappyHorse keeps the source’s aspect ratio.
  • To keep a character or product identical from one video to the next, reuse the same reference images and refer to them the same way in the prompt.
