What is HappyHorse?
HappyHorse is an open-source AI video generator that creates cinema-grade clips with synchronized audio in one pass. It supports both text-to-video and image-to-video, so you can describe a scene or upload a reference image and generate a video from it. The product focuses on fast results, native lip-sync in seven languages, high-resolution output up to 2K, and a range of visual styles from photorealistic to anime. It also offers commercial-friendly licensing, API access, batch generation, and tools for teams and high-volume production. The goal is to make video creation simpler by handling video, dialogue, ambient sound, and effects together, without a separate post-production workflow.
