MP4Maketags

MP4Maketags is a software tool concept used to generate and embed metadata tags into MP4 files. It aims to automate the creation of MP4 metadata structures and streamline tagging workflows for large collections, often supporting batch operations and template-driven tagging.

Typical functionality includes mapping user-provided fields such as title, artist, album, genre, year, track number, and cover art to the corresponding MP4 metadata keys and atoms (for example, the title commonly appears as a QuickTime/MP4 tag such as “©nam” and artwork as “covr”). The tool writes or updates the ilst metadata in MP4 containers, preserves existing streams, and supports Unicode. It commonly accepts metadata from CSV, JSON, or command-line input and may provide templates to enforce consistent tagging across files.

MP4Maketags is referenced in various tagging toolchains and scripting workflows for media organization. It is not necessarily a single standardized project; rather, the name is used to describe components or utilities that perform MP4 tagging as part of broader media-management pipelines. Compatibility considerations include varying support for specific tags across players and platforms; some fields may display differently or be hidden in certain environments.
