LoadVideoDataSetFromFolder - ComfyUI Built-in Node Documentation - ComfyUI

Loads all supported video files from a selected folder inside the ComfyUI input directory and returns them as a list of video references. This node returns lazy video references, so frames are decoded only when another node actually needs them.

Inputs

Note: The selected folder must contain at least one supported video file. Supported extensions are MP4, AVI, MOV, WEBM, MKV, and FLV. If no supported video files are found, the node raises an error.
