Kling Video O1 is the world’s first unified multimodal video model from Kuaishou. Unlike previous tools that separate creation and editing, Video O1 handles everything in one place — generate cinematic videos from text or images, then edit, extend, or restyle them using simple conversational commands. With up to 7 image references, start/end frame control, and pixel-level semantic editing, O1 replaces traditional masking and rotoscoping workflows entirely on A2E.
