Alibaba's HappyHorse 1.0 is a high-end video generation family: text-to-video, image-to-video, reference-guided video, and natural-language video editing. Emphasizes synchronized native audio with picture (dialogue, ambience, and effects in one pass where supported), multilingual lip-sync, and 1080p-class delivery. Positioned for cinematic social, localized campaigns, and rapid storyboard-to-cut workflows. Official API access is available on fal.ai across multiple endpoints.

It addresses the hardest user complaint about AI video, convincing sound and lip-sync with motion, not only pixels. Strong fit when you need dialogue-forward clips or localized performances without a full audio post stack.
