The hybrid 2mp4 approach outperforms single‑codec encoding in terms of weighted bitrate (median 8.2 Mbps vs. 12.4 Mbps for H.264 and 7.1 Mbps for pure H.265, but with better random access performance). Preservation metadata (fixity, provenance) was embedded in MP4 udta atoms without breaking standard compliance.

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. Extract technical metadata:

Digital archives increasingly ingest Full HD (1080p) video from heterogeneous sources (digitized film, born-digital recordings, surveillance footage). The placeholder string "archivefhdsone454 2mp4" originated from an internal University of Sone archive test batch, where “FHD” indicates full HD resolution, “Sone” refers to the Sone Acoustics Lab’s video collection, and “454” is the batch ID. “2mp4” denotes the second method in a comparative MP4 encoding experiment.
