LongCat-Video

LongCat-Video is built for sequences that run longer than the usual short bursts. You can start from a prompt, a style frame, or a short reference and guide framing, lens language, choreography, and transitions while the model preserves faces, hands, materials, and lighting across shots. Editing happens inside the same pipeline, so you extend a take, retime action, replace backgrounds, or refine regions without restarting the scene. The result is footage that stitches together cleanly for ads, explainers, product demos, and storyboards.
