: Stands for Full High Definition, which refers to a video resolution of 1080p (1920x1080 pixels). This is a common standard for high-definition video content, offering a significant improvement in video quality compared to standard definition (SD) or high definition (HD) 720p.

As digital libraries expand, the need for efficient storage and retrieval of Full High Definition (FHD) content becomes paramount. This paper examines the technical advantages of the MP4 (MPEG-4 Part 14) container for long-term archiving. We explore the balance between compression efficiency and metadata retention, specifically focusing on the "fhdarchivesone" protocol for systematic file versioning. 1. Introduction
