LoadVideoTextDataSetFromFolder - ComfyUI Built-in Node Documentation

This node loads a dataset of video files and their corresponding text captions from a specified subfolder inside the ComfyUI input directory. It returns two lists: lazy video references (frames are decoded only when needed downstream) and their associated captions. The node supports common video formats such as MP4, AVI, MOV, WEBM, MKV, and FLV, and can also handle nested folder structures with repeat‑count prefixes (e.g. 5_classname/) used by tools like kohya‑ss/sd‑scripts.

Inputs

Parameter	Description	Data Type	Required	Range
`folder`	The subfolder containing video files and `.txt` caption files. Select from the available subfolders in the ComfyUI input directory.	STRING	Yes	Combo: dynamic list of all subdirectories inside the ComfyUI input folder

Outputs

Output Name	Description	Data Type
`videos`	Lazy references to the loaded video files. Frames are decoded only when connected to a downstream node that processes them. Each element corresponds to a video from the input folder.	VIDEO (list)
`texts`	List of text captions, one per video. If a video does not have a matching `.txt` file, its caption is an empty string.	STRING (list)
