HappyHorse 1.0 Is Coming to Picsart - Here's What to Expect

HappyHorse 1.0 is coming to Picsart, bringing a new level of control, consistency, and realism to AI video creation. Built by Alibaba’s Future Life Lab, this 15-billion-parameter AI video model introduces multi-shot storytelling, native multilingual audio, and frame-anchored image-to-video – all generated in a single pass.

When it launches, HappyHorse 1.0 will be available across the AI Video Generator, AI Playground, and Flow. Instead of stitching together clips or layering audio afterward, you’ll be able to generate cohesive, cinematic sequences with synchronized sound directly from a single prompt.

Here’s a first look at what HappyHorse 1.0 brings to the table and why it matters for your creative workflow.

Multi-shot storytelling in a single generation

HappyHorse 1.0 lets you chain up to five sequential shots in one generation. Each shot can run between one and twelve seconds, and the entire sequence is generated together as a cohesive unit. Character identity, wardrobe, lighting, and atmosphere stay consistent across every shot – something that has traditionally been difficult to maintain with AI-generated video.

This replaces the typical workflow of generating clips one by one, stitching them together manually, and trying to correct inconsistencies. With HappyHorse 1.0, a sequence behaves more like a storyboard brought to life in one step.

You can define up to three reference elements – such as a character, product, or location – and reuse them across the entire sequence for visual continuity. This makes multi-shot generation especially powerful for mini-narratives, product walkthroughs, storyboard previews, and brand videos where consistency across cuts is essential.

Multilingual AI video, generated in one pass

HappyHorse 1.0 generates dialogue and lip-synced speech natively as part of the video itself. It supports six languages – English, Chinese (Mandarin and Cantonese), Japanese, Korean, German, and French – and builds the mouth movements and audio together in a single generation.

This is not dubbing layered on top of pre-rendered visuals. The model creates both the visuals and the spoken language simultaneously, resulting in more natural lip-sync and timing. The difference becomes especially noticeable in close-up shots or dialogue-heavy scenes where mismatched audio can break immersion.

For creators working across regions, this opens up new possibilities. You’ll be able to produce localized ad campaigns without reshooting, create multilingual social content from one concept, and generate spokesperson videos that feel natural in each language without relying on voice actors or dubbing.

First-frame and last-frame control for image-to-video

HappyHorse 1.0 introduces more precise control for image-to-video generation through first-frame and last-frame anchoring. Instead of starting with a single image and letting the model guess the motion, you can define both the beginning and the end of a clip.

Upload one image as the starting frame and another as the ending frame, and the model generates the motion between those two points based on your prompt. This creates a much more predictable and controlled outcome, especially for transitions and transformations.

You can also combine frame control with reference elements to maintain consistency for characters or products throughout the motion. This makes the feature especially useful for product reveals, before-and-after demonstrations, logo animations, and transition shots between scenes in a larger project.

Where you’ll find HappyHorse 1.0 in Picsart

When HappyHorse 1.0 launches, it will be available across three Picsart tools, each designed for a different stage of the creative process.

In the AI Video Generator, you’ll be able to select HappyHorse 1.0 as a model option for both text-to-video and image-to-video creation – ideal when you want a finished clip from a single prompt. In AI Playground, you’ll be able to experiment with it alongside other models to refine prompts and explore different styles. And in Picsart Flow, you’ll be able to chain HappyHorse 1.0 into automated multi-step pipelines for producing video content at scale.

HappyHorse 1.0 quick specs

HappyHorse 1.0 runs on a 15-billion-parameter unified Transformer architecture that generates visuals and audio together. It produces 1080p MP4 video with durations ranging from 3 to 15 seconds, defaulting to 5 seconds.

It supports 16:9, 9:16, and 1:1 aspect ratios, along with Pro and Standard quality modes. Multi-shot generation allows up to five sequential shots, each between 1 and 12 seconds. You can define up to three reference elements per task.

For image-to-video, it supports two frames – first and last – for anchored motion. Audio includes dialogue, sound effects, and ambient layers, all generated natively and toggleable. Generation speed averages around 10 seconds, with previews available in about 2 seconds. Languages supported: English, Mandarin, Cantonese, Japanese, Korean, German, and French.
