Features
- Synced sound & ambience——Thunder lands on lightning, splashes land on slow-mo peaks — audio and picture align in a single generation. Silent clips are the past; sound is the default.
- Chart-topping quality——Per the April 2026 charts (via Pollo's public page): HappyHorse-1.0 scored T2V 1333 and I2V 1392, topping both Artificial Analysis lists about 60 points ahead of Seedance 2.0 (1273/1355).
- Native Chinese prompts——Dialogue lip-sync in Chinese, English, Japanese, Korean, German and French. Write lines in Chinese directly — no English translation needed, mouths match every word.
- One photo is enough——Pure text becomes a film (T2V); one start frame comes alive (I2V); add a reference to lock the same character. Multi-shot stories stitch 5–10s cuts into about 30s.
How it works
- Drop a photo or a line Upload a product or old photo as the start frame — or nothing at all: one descriptive sentence in Chinese works.
- Pick format and sound Landscape for YouTube, vertical for TikTok; sound defaults to native sync, dialogue mode needs your exact lines.
- Generate and publish Each run is 5–10 seconds; multi-shot stories stitch to about 30. Download with sound and post.
FAQ
- Is Happy Horse free to try?
- Yes — start free. Generate Happy Horse 1.1 clips inside Loomi after login; each run costs a small credit (about 25). Try free first, then decide. Aggregator sites mostly offer limited trials — check each platform's rules.
- Can I make a video from just one photo?
- Yes — one photo is enough. Upload it as the start frame; small moves like blinks or drifting clouds work best. A clear front-facing, well-lit face wins most. Big dance moves risk melting faces — start with subtle motion.
- Does it generate videos with synced sound?
- Yes — and it is native, not dubbed later. Thunder matches lightning and splashes match slow-mo inside the same generation. Pick lip-sync mode and paste exact lines for talking heads; pick silent if you want none.
- Does it understand Chinese prompts?
- Yes — write prompts and lines in Chinese directly. The model natively supports Chinese, English, Japanese, Korean, German and French. Translating to English first can lose the details you actually want.
- Is Happy Horse open source and commercial-use?
- The model itself is commercial-friendly. HappyHorse is open-weight and cleared for commercial use. Faces and branded products still need your own releases, and labeling AI output is recommended — see platform terms.
- How is it different from Kling or Seedance?
- Sound and Chinese. Per the April 2026 charts (via Pollo's public page) it led both lists with T2V 1333 and I2V 1392, about 60 points ahead of Seedance 2.0. Native synced audio plus Chinese lip-sync is the edge Kling and Seedance never spelled out — verify with your own test.
- How long can one generation be?
- Each run is 5–10 seconds. Multi-shot mini stories generate per shot and stitch to about 30 seconds. Films over a minute are out — split them into boards and generate shot by shot.
- Can I use it on my phone?
- Yes — right in the mobile browser. Upload, pick format, write the line, all on one web page. Switch to 9:16 vertical in one tap, download the clip and post to TikTok or Reels.
