Upload a still image and animate it into a video clip. The model preserves the original composition while adding realistic motion.

Subject + Video to Video (SV2V)
Replace or insert a specific subject from a reference image into an existing video. The original motion, composition, and unaffected regions stay untouched.
Cinematic depth & multi-shot
Wide-aperture shallow depth-of-field, stable character positioning across cuts, and high-speed action—built for short dramas, ads, and dynamic sequences.

FAQ
Who built HappyHorse 1.0?
HappyHorse 1.0 was built by Alibaba’s Future Life Lab (Taotian Group) under the ATH AI Innovation Unit. The project is led by Zhang Di, former VP at Kuaishou and the technical lead behind Kling AI. Model weights are released on Hugging Face under the Apache-2.0 license. On HeadSwap you can run HappyHorse 1.0 fully in the browser — no local GPU, no setup, and no Hugging Face account required.
What's the maximum video length and resolution?
HappyHorse 1.0 generates up to 15 seconds of 1080p video with multi-shot transitions in a single render. The model supports five aspect ratios — 16:9, 9:16, 4:3, 3:4, and 1:1 — so you can output for YouTube, TikTok, Reels, Shorts, and square ads directly without re-rendering. For higher resolution, pair HappyHorse with HeadSwap’s upscale tool to push clips up to 4K.
What other video models does HeadSwap have?
HeadSwap hosts a full lineup of leading AI video models in one dashboard: HappyHorse 1.0, Wan 2.7, Wan 2.6, Kling 3.0, Kling 2.6, Veo 3.1, Seedance 2.0, Sora 2, and Grok Imagine. Compare outputs from different models side by side and pick the best one for each shot.
What is HappyHorse best at?
HappyHorse 1.0 is strongest at cinematic output with wide-aperture shallow depth-of-field, multi-shot consistency with stable character positioning across cuts, and high-speed dynamic action — motorcycle chases, racing sequences, suspenseful confrontations, and romance narratives with nuanced camera movement. It’s a great pick for short dramas, ads, and dynamic sequences where motion realism and character continuity matter most.
What generation modes does HappyHorse 1.0 support?
HappyHorse 1.0 supports five generation modes: Text-to-Video (T2V), Image-to-Video (I2V), Subject-to-Video (S2V), Video-to-Video (V2V), and Subject-and-Video-to-Video (SV2V). S2V lets you insert a person or object from a reference photo into a generated scene. V2V modifies an existing clip while keeping its original motion. SV2V combines both — use a reference subject and an existing video together for full creative control on HeadSwap.
Is HappyHorse free to use on HeadSwap?
Yes. New users get free credits on signup and 30 bonus credits daily through check-in — enough to test HappyHorse 1.0 across all five generation modes. No credit card required, no waitlist, and no Alibaba account needed. For higher daily limits, priority queue, and commercial rights, HeadSwap offers affordable Premium plans. HappyHorse 1.0 runs fully online — no API key, no Hugging Face setup, and no local hardware required.
Does HappyHorse generate audio automatically?
Yes. HappyHorse 1.0 produces synchronized audio-visual output by default. The model generates lip-synced dialogue, ambient soundscapes, and emotionally expressive vocals together with the video in a single pass — no separate text-to-speech, dubbing, or sound-design step required. Audio generation is optional; you can turn it off if you only need the video track for editing in your own pipeline.
Can I use HappyHorse videos for commercial work?
Yes. Videos generated with any HeadSwap paid subscription plan can be used for commercial purposes — ads, social media monetization, client deliverables, product marketing, and more. You retain full ownership of the videos you create, with no watermark and no extra licensing fees. There are no per-clip royalties or attribution requirements. For high-volume commercial workflows, the Premium plan unlocks faster priority generation and higher daily limits.
