The rapid growth of video archives presents challenges in balancing storage efficiency, visual fidelity, and future accessibility. This paper introduces ArchiveFHD Sone 454, a test corpus designed to evaluate the trade-offs of MP4 encoding variants in archival contexts. Using the identifier 2mp4 to signify second-generation MP4 compression techniques, we analyze compression ratios, perceptual quality (VMAF scores), and preservation metadata integrity. Our results show that a hybrid scheme — combining AVC (H.264) for motion-stable content and HEVC (H.265) for high-detail scenes — achieves a 34% storage reduction over uniform encoding while retaining forensic-grade quality. The archivefhdsone454 framework offers a replicable benchmark for audiovisual archives migrating from legacy codecs.
The archivefhdsone454 experiment reveals that MP4 can be a preservation‑ready access format if encoding decisions are documented per segment. However, reliance on proprietary codec features (e.g., H.265’s dependent slices) may hinder future migration. We propose an extension called “2mp4+” that includes a sidecar XML with encoding parameters and decoding dependencies. archivefhdsone454 2mp4
