# ViduExtendVideoNode - ComfyUI Built-in Node Documentation

> The ViduExtendVideoNode generates additional frames to extend the length of an existing video.

The ViduExtendVideoNode generates additional frames to extend the length of an existing video. It uses a specified AI model to create a seamless continuation based on the source video and an optional text prompt.
