The Grok Video Extend node uses an AI model to create a seamless continuation of an existing video. You provide a short video and a text prompt describing what should happen next, and the node generates a new video clip that follows on from the original.

​
Inputs

Parameter Constraints:
  • The video input must be an MP4 file between 2 and 15 seconds in length and cannot exceed 50MB in file size.
  • The prompt must contain at least one character (whitespace is trimmed).
  • The model parameter is a dynamic combo. Selecting the “grok-imagine-video” option reveals a nested duration parameter, which controls the length of the extension in seconds (default: 8, range: 2 to 10).
