Reference-driven 3-15s video generation at $0.084 per second.
Alibaba's Happy Horse 1.1 Image to Video animates a single still photo into a 720P or 1080P clip with livelier motion and steadier faces, billed at $0.13 per second for 720P and $0.16 per second for 1080P across 3-15 second durations. Trading manual keyframing, separate motion design, and slow render queues for one image-and-prompt step, this release fixes the sluggish action and uneven face handling of the 1.0 generation for creators, marketers, and product teams. For developers, Happy Horse 1.1 Image to Video on RunComfy can be used both in the browser and via an HTTP API, so you don't need to host or scale the model yourself.
Ideal for: Portrait Animation | Product Reveal Clips | Cinematic Ad Teasers
Happy Horse 1.1 Image to Video reads one source photo plus a short prompt and returns a coherent clip, keeping the subject's identity, color, and framing close to the original frame while adding believable motion.
This release sharpens the weak spots of the 1.0 generation. Action that used to feel sluggish now carries more pace and weight, and a wider range of faces — including Asian faces — holds a steadier likeness across the shot.
Output format: resolution 720P or 1080P / fps 24 / duration 3-15s / input a single still image / aspect ratio follows the source image (no separate ratio control).

Lead with motion verbs like drift, orbit, or push in so the model knows what should move, then state what must stay fixed, such as identity, packaging, or background. Because Happy Horse 1.1 Image to Video animates your exact photo, describing one clear visual beat per clip gives the most reliable results.
