  • Ethical protocol for handling potentially sensitive content (redaction, non-distribution).

    • 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.

    We release the archivefhdsone454 test set under CC‑BY‑NC. Future work will extend the framework to 4K and incorporate neural‑based codecs (e.g., VVC, AV1). The 2mp4 hybrid encoding strategy is recommended for mixed‑content video archives with moderate storage budgets. archivefhdsone454 2mp4
