Veo 3.1 Extend Video

Released in Late 2025, Google's closed-source Veo 3.1 Extend Video is a standalone model specialized in video continuation. It takes an existing video file as input and generates a new, extended segment that seamlessly continues the action and style. This makes it a powerful tool for lengthening shots or expanding on existing footage without needing to regenerate the entire scene. The model operates by analyzing the final frames and motion of the input video to produce a logical and visually consistent continuation, offering a unique post-production capability.
