A sequential identification number, suggesting this is part of a large data set (over 900 files) [1]. 2. Potential Contexts for this Footage ARCHIVE-FHD-JUQ-986.mp4
The proliferation of high‑definition (HD) video recordings in the early 21st century has created unprecedented opportunities for cultural heritage institutions, yet it has also amplified challenges related to long‑term preservation, forensic authentication, and sustainable re‑use. Using the representative file ARCHIVE‑FHD‑JUQ‑986.mp4 —a 1080p, 30 fps, 12‑minute documentary‑style capture of a historic site—we develop and validate a comprehensive workflow that (i) extracts and normalizes embedded technical and descriptive metadata, (ii) assesses bit‑level integrity through cryptographic hashing and error‑vector analysis, (iii) applies perceptual video quality assessment (VQA) to gauge degradation, and (iv) generates a richly linked archival record conformant with the OAIS (Open Archival Information System) model and the PREMIS (Preservation Metadata: Implementation Strategies) standard. The workflow is implemented in an open‑source toolchain (FFmpeg + ExifTool + PyMediaInfo + VMAF + Preservica API) and evaluated on a corpus of 500 HD video assets spanning 2005‑2020. Results show a > 99.8 % success rate in detecting bit‑rot, a > 95 % correlation between automated VMAF scores and expert visual appraisal, and a 30 % reduction in manual cataloguing time. We argue that a systematic, standards‑based approach—exemplified by the case study of ARCHIVE‑FHD‑JUQ‑986.mp4 —is essential for the sustainable stewardship of HD moving‑image heritage.
