Scripts with no obscure dependencies, mac and windows friendly, interactive or with defaults, fast.

Script	Description
videoFrameExtractor.py	Interactive script to extract frames, super fast. OpenCV required, nothing more. Accepts file or folder input, configurable stride, and start/end frames.
yobb_to_yolo_bbox.py	Converts oriented bbox labels into normal YOLO bbox. Interactive, multithreaded, error-checking, and continues processing even on errors. If an image folder is provided, it verifies that images have their label pairs. Creates a backup before overwriting labels.
mass_rename.py	Renames label/image pairs with the same random name. Usage: python3 script.py labels_path images_path.
resize.py	Interactive script to resize images inside a folder using PIL. Supports interpolation methods: nearest, bilinear, bicubic, and lanczos. "All" option available for comparison.
download_coco_categories.py	Downloads specific classes from the COCO dataset, multi-threaded, and creates YOLO-format label files. Interactive with prompts and a progress bar, but also allows direct CLI usage: py script.py 0 (class 0) or py script.py 1,33,56,57,70 download_path
Structure.py	Recreates folder structure while allowing selection of how many files to copy from the original folders. Useful for creating validation datasets from training datasets.
Json_to_Folders.py	Sorts files into folders based on selected attribute values from a JSON file. Prompts for the number of files per folder with an option to process all files.
videocrop_path_top_right_bot_left.py	Crops a video by removing specified pixel amounts from its sides (top, right, bottom, left). Example usage: py script.py video.mp4 100 0 200 20 (removes 100 pixels from top, 0 from right, 200 from bottom, 20 from left).
nospaces.swift	Removes Python-breaking characters from filenames in a chosen folder and replaces spaces with underscores. Usage: swift nospaces.swift (prompts for folder if not provided). Logs changes (old name → new name) in a text file within the folder.
