HappyHorse 1.1 Reference Video (Alibaba)

Overview

HappyHorse 1.1 Reference is Alibaba’s reference-guided video generator. You provide 1–9 reference images plus a written scene description. The model combines those references into a single short clip with stronger subject consistency. It helps you keep a character, outfit, or product stable across a generated shot.

What you can build

• Character-consistent short scenes for ads, reels, and branded content
• Product demo clips that keep packaging shape, labels, and color consistent
• Multi-item fashion shots where outfit, accessories, and props stay recognizable
• Visual story beats that reuse the same cast across multiple clips
• Style-and-subject locked concept pitches for storyboards and pre-vis

Inputs

• 1–9 reference images you want the model to preserve (JPEG/JPG/PNG/WEBP).
• Each reference image must be at least 300 px wide and 300 px tall.
• Each image must stay within an aspect ratio range of 1:2.5 to 2.5:1.
• Each image can be up to 20 MB.
• A written scene description that explains the action, camera, lighting, and style.
• In the description, point to your references by index, like [Image 1], [Image 2], and so on.
• The scene description supports up to 5,000 non‑Chinese characters or 2,500 Chinese characters.
• A target clip length between 3 and 15 seconds.
• A required output resolution tier: 720p or 1080p.
• An optional output aspect ratio.
• If you pick auto aspect ratio, the system chooses the closest match from your first reference image.
• An optional toggle to add a small “HappyHorse” watermark in the bottom-right corner.
• An optional numeric random seed for more repeatable variations.

Outputs

• One generated video clip.
• The clip follows your chosen duration and resolution tier.
• The frame shape follows your chosen aspect ratio setting.
• If enabled, the output includes a visible “HappyHorse” watermark in the bottom-right corner.

Limitations

• Clips are short. The maximum length is 15 seconds.
• Output resolution is limited to 720p or 1080p.
• Reference fidelity depends on input quality.
• Small, blurry, compressed, or low-light reference images can cause identity drift.
• Conflicts between your description and the reference images can reduce consistency.
• Busy scenes with many subjects raise the chance of warped hands, logos, or fine text.

Safety & compliance

• Platforms commonly apply automated filtering to inputs and generated outputs.
• Don’t submit illegal content, sexual content involving minors, or instructions for wrongdoing.
• Don’t upload reference images you don’t have rights to use.
• Avoid prompts that request real-person impersonation or deceptive political content.
