Text-to-Video Generation
With HappyHorse-1.0 API, text-to-video generation makes it possible to turn natural language prompts into dynamic video content for storytelling, visual ideation, marketing concepts, short-form clips, and other creative uses. This mode is especially useful when a project starts from an idea rather than an existing visual, giving users a direct way to transform written concepts into more vivid and expressive video results.
Image-to-Video Generation
HappyHorse-1.0 API also supports image-to-video generation, making it easier to transform reference images into more engaging video outputs with stronger visual continuity. This mode is well suited for character animation, product motion, stylized scene generation, and other reference-based creation needs where preserving the original image remains an important part of the result.
