It is supported by popular media players like VLC, QuickTime, and Windows Media Player, as well as editing tools such as Adobe Premiere Pro and Final Cut Pro. The format uses a hierarchical structure with boxes (or atoms) to organize data, supporting advanced features like streaming, metadata embedding, and DRM (Digital Rights Management) for secure content distribution.
