LORENZ Building an integrated digital media archive and legal deposit

  1. 1. Building an integrated digital media archive and legal deposit – planning and innovations for the preservation of assets like cinematographic works and ancillary data Vladimir Torov C.E.O. / Undersecretary iMM rešitve d.o.o. Ministry of Justice Tom Lorenz Managing Partner Cube-Tec International FIAT/IFTA Conference October 23rd 2019 Dubrovnik
  2. 2. Short Introduction
  3. 3. Introduction ■ With my presentations I usually try to give you insights into exciting projects in which Cube-Tec is involved. ■ Cube-Tec has realized different projects in the region where the current FIAT/IFTA world conference takes place, it is an obvious idea and a special pleasure to include an experienced project architect as my co-presenter. ■ For this I have asked Vladimir Torov, Vladimir works for the Ministry of Justice in Slovenia and as a consultant for media archives. ■ Unfortunately he can not be here today due to an unforeseeable business meeting at his ministry. However, he sent me his input and I will present a summary of his paper. ■ With his presentation he will provide the point of view from an archive client explaining the requirements in public national archiving organizations. ■ And my role will be to show how Cube-Tec solves such requirements with highlighting some new and innovative details. ■ In this talk we will have a special focus on requirements and solutions for digital media archive and legal deposit especially for the preservation of assets like cinematographic works and ancillary data.
  4. 4. About Cube-Tec
  5. 5. About Cube-Tec ■ 1990 Founding of the engineering offices Houpert Digital Audio (HDA), in the Innovation & Technology Center Bremen, Germany ■ 2005 Founding of Cube-Tec International with headquarters in Bremen, Germany ■ 2010 Founding of Cube-Tec North America LLC in Asheville, North Carolina Cube-Tec International headquarter Technology Park Bremen, Germany
  6. 6. Cube-Tec Company Background ■25 year company background in in digital signal processing and audio and audiovisual media preservation ■Starting in the mid 90 pioneering large-scale audio migration strategies with a strong emphasis on quality-control ■Inventor of the first dedicated “migration workstation” ■In 1995 the IRT (broadcast research institute for the German speaking public broadcaster) has analyzed the requirements for the mass digitization of analog audio tapes in the broadcast archive. We developed a product to fulfill the demand. IRT invented the name QUADRIGA. The acronym QUADRIGA stands for “Quality from Analogue to Digital Rigorously Analysed“ ■Leading and participation in different European Research projects, like: ■PrestoSpace - Preservation towards storage and access. Standardised Practices for Audiovisual Contents Archiving in Europe ■DAVID - Digital AV Media Damage Prevention and Repair ■VideoStar, CineXPRES, AVEROS, EDFIRE

  8. 8. System Requirements (V. Torov)
  9. 9. Summary of Vladimir Torov‘s presentation part Challange in most analogue film archives is how to transform from analog to digital • Analysis of current system • Choosing standards and good practices around the EU • Checking material and how to work with it • Creating workflows and identify bottlenecks • Identify hardware and software solutions • Creating tender and preparing legislation changes • Choosing right solution and partner ■ Vladimir Torov – expert in AV digital archives - procedures, legislation and system tender creator and project manager of establishing digital film archive (former employee of Slovenia Archives, still their advisor/ project manager as iMM rešitve d.o.o. )
  10. 10. Summary of Vladimir Torov‘s presentation part Most common problems are: • current procedures are only for analogue archives • make decisions how far the transformation should go • lack of skilled and technical employee and • not enough technical knowledge or support from (analogue) archivists • mindset is not prepared for transition to digital
  11. 11. Summary of Vladimir Torov‘s presentation part Request of solutions: Hardware (based on standardized high-end server technology) • system and network – 10 Gbit/s network, optical fiber backbone, storage • digitisation device (film scanner must support 8, 9.5, 16, 35 mm film formats incl. the different sound track formats) Software (based on customized out-of-the-box software) • MAM system for archivists • Workflow system with high flexibility (create and change workflows) • DCDM Checking (Digital Cinema Distribution Master) • DCP Creation (Digital Cinema Package) • User rights and role management • Integration via xml, REST
  12. 12. Summary of Vladimir Torov‘s presentation part MAM and Workflow Solution • solution must be compatible with existing archive database and fully integrated with support of all workflows. • database for metadata fields definition according to FIAF recommendation • support different AV formats and document formats • transcoding AV formats into uncompressed archive format and preview format • support for cinematographic works in DCDM and DCP format • QC for data and AV material - analysis and creating reports • advanced web based media player • proxy generator with watermark (logo insertion) • system need to be fully localized for Slovenian language THANK YOU FOR YOUR PATIENCE AND HOPE TO SEE YOU SOON !

  13. 13. Solutions (T.Lorenz)
  14. 14. Legal deposit for film and video files High demand because of: ■ Long-term availability of preserved assets ■ Standards conformity of the assets and metadata ■ Verifiability of a preservation procedure (conform to OAIS Reference Model) ■ Very large preservation files (> 1 TB per single deposit) This requires special procedures to assure: 1. Correctness of media assets 2. Correctness and completeness of metadata 3. Correctness of the preservation process
  15. 15. 1. Correctness of media assets 2. Correctness of metadata 3. Correctness of the preservation process
  16. 16. 1. Correctness of media assets 2. Correctness of metadata 3. Correctness of the preservation process extraction and preserving of technical metadata incl.
  17. 17. Verification and QC ■Verification and documentation of data that have been delivered ■Verification of defined preservation file structure (SIP) (checking conformity for mandatory and optional files) ■Importing delivered metadata and allow to add missing metadata ■Automatic logging and protocolling of all processing step ■Hand-over OAIS conform SIP structure for long-term preservation
  18. 18. Verification and QC of Essence files Preservation Master Files ■dpx or tiff sequences ■DCDM (Digital Cinema Distribution Master) ■Lossless compressed files like mkv/ffv1 ■JPEG 2000 (mathematically lossless) ■Uncompressed MXF Access Copies (mezzanine & proxy files) ■ProRes ■MP4 Ancillary data files (reports, film poster) ■PDF/A ■JPEG ■TIFF ■... ■ Format Characterization (incl.) ■ format identification, ■ format validation ■ feature extraction and ■ policy-based assessment ■ including commercial and open source tools ■ QUADRIGA QC View ■ Fraunhofer DCP Validator ■ JHOVE ■ ffprobe...
