Frequently Asked Questions

  • What is HappyHorse best at?

    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.

  • Which generation modes does HappyHorse support?

    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.

  • How are HappyHorse credits calculated?

    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.

  • How long can a HappyHorse video be?

    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.

  • Do I need to sign up, and is it free to try?

    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 MakeFun AI β€” no GPU, no install, and no API key.

  • Can I use the videos I generate for commercial projects?

    Yes. Videos generated on a paid MakeFun AI plan can be used commercially β€” 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.

  • Where do my videos go after generation?

    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.
