HappyHorse 1.1 AI Video Generator

HappyHorse is a multi-modal video model built by Alibaba ATH. It is strongest on lip-synced dialogue, ambient sound, high-speed action and multi-shot continuity, which makes it a fit for advertising, short drama and social marketing.

Four: text-to-video from a prompt alone, image-to-video from a first frame, reference-to-video with 1 to 9 subject references, and video-edit, which repaints an uploaded clip or swaps a subject in it while keeping the original motion.

By output length and resolution: 60 credits per second at 720P and 100 credits per second at 1080P. Video-edit is pre-charged at twice the input clip length, capped at 15 seconds, and unused credits are returned.

Up to 15 seconds of 1080P multi-shot storytelling in one job. For anything longer, generate the beats separately and keep them consistent by reusing the same subject references.

You can start for free. New accounts get bonus credits on signup, there is no credit card required, and the free plan has no daily generation limit. You can also claim extra credits every day by checking in. Everything runs in the browser on HeadSwap — no GPU, no install, and no API key.

Yes. Videos generated on a paid HeadSwap plan can be used commercially — ads, social media monetization, client deliverables and product marketing. You keep ownership of the output, with no watermark, no attribution requirement and no per-clip royalties.

Every finished job appears in the My Results tab beside the generator, where you can preview, download, share or delete it. The list keeps the last 3 days of generations, so download anything you want to keep before it rolls off.
