HappyHorse 1.0 is a multimodal AI video generation model designed to produce broadcast-quality videos with native audio. It generates 1080p output in a single forward pass and aligns speech to lip motion at sub-pixel precision. The model supports text-to-video and image-to-video generation, making it useful for ads, explainers, previews, and localized content. It also handles seven languages for lip-sync, including English, Mandarin, Cantonese, Japanese, Korean, German, and French. With built-in audio synthesis, it removes the need for separate TTS or post-production audio stitching, delivering a faster and more integrated workflow.
