MetaZ
MetaZ is a macOS MP4 metadata editor that helps users tag video files with titles, artwork, chapters, and other library information.
What is MetaZ?
MetaZ is a native macOS metadata editor for MP4 video files. It helps users organize movies, TV episodes, and other compatible media by editing tags such as title, description, artwork, genre, ratings, and chapter information. The app is useful for people who maintain local media libraries and want cleaner metadata for playback software and Apple media workflows. MetaZ can search for metadata from supported online sources, apply results to files, and save reusable presets for repeated tagging tasks. It also includes features for handling multiple files, plugin-based extensions, and AppleScript-related automation workflows. Published by Maven-group, MetaZ is aimed at Mac users who want more control over MP4 library details than basic file renaming provides.

Safety overview
Status: Mostly safe
MetaZ is a media-tagging utility, so accessing the files you choose to edit is a normal part of how it works. Changes made in the app can overwrite metadata in your MP4 files, so it is wise to keep backups of important media before making large batch edits. Network access may be used when searching for metadata from online sources. For ordinary use, its behavior is consistent with a desktop utility for managing local media files.
Recommendation: Keep MetaZ if you actively manage a local MP4 video library or need to clean up media tags on your Mac. If you no longer edit video metadata, you can remove it without affecting macOS, though any workflows built around its presets or automation will no longer be available.
