VideoRandomTemporalCrop - ComfyUI Built-in Node Documentation - ComfyUI

Randomly crop a continuous range of frames from an input video. The number of frames to keep is set by the length parameter, and the start position is chosen randomly using the seed parameter. The node operates lazily, meaning it does not process the entire video until the output is used downstream.
