Veo 4 is an AI video generation platform designed for cinematic, controllable content creation. It accepts text prompts plus image, video, and audio references in a single generation. The product emphasizes natural language guidance, native lip-synced audio, accurate motion and camera replication, and consistent characters, clothing, text, and scenes across shots. It also supports video extension and targeted editing, allowing users to merge clips, replace elements, or refine segments without rebuilding the entire video. The result is a flexible tool for producing polished, multi-shot videos quickly.
