  1. Motion Picture Scanning FADGI SubgroupApril 22, 2013 Hosted by The Library of Congress and The National Archives and Records Administration Coordinators: Criss Kovac & Heidi Holmstrom

  2. Agenda • 10:00 – 10:10: Welcome and Introduction • 10:10 – 10:40: Round Robin from Participants • What is your institution doing • What outcomes / projects would you like to see come from this group • 10:40 – 10:50: NARA's Motion Picture Digitization developments to date • 10:50 – 11:30: Discussion of Proposed Projects / Areas of Interest

  3. Film Scanning at NARA • Altra HD scanner • Capturing 1920x1080 Uncompressed 24PsF AVIs • Stored on SAN • Transcoding 29.97fps SD MPEG2 (50Mbps) derivatives • Used as source file for reference DVDs • Stored on NAS • Spirit 4K scanner • Current workflow: • High-interest films captured as 2K DPX • Color correction and dust/scratch removal in Digital Vision • Produce 2K DCP and other derivatives • Files stored on SAN, NAS, and hard drives (redundancy) • Future workflow: • Preservation scanning at 2K/4K, 16-bit LOG, 4:4:4 raw DPX • Storage: ?

  4. Common Issues • Limited funding/staff/equipment • The size of DPX file sequences makes it difficult to verify them as they are moved across systems • Lack of software allowing for a quality check of the visual appearance of a DPX sequence • DPX must be transcoded to a smaller file type in order for such software to be used

  5. Ideas from Peer Institutions • Ingesting DPX files into a transcoding suite could serve as an integrity check—2 steps in 1 • Use of digitization workflow manager to help the flow of information across systems and update metadata • Use of visual QC tool that checks for horizontal and vertical shifts so scans can be rejected based on instability detected in perf area • Use of ODTs (Output Display Transforms) to ensure we’re producing files that will represent the correct “look” of the film original across formats and platforms

  6. NARA Procedures and Standards • SOPs in place for all digital processes • Implemented Baton software for automated QC checks on files • Implemented Radiant Grid for transcoding to defined derivatives • Information on QC checks added to NARA’s Products & Services page: • http://www.archives.gov/preservation/products/reformatting/mopix-digital.html

  7. Proposed Ideas / Areas of Interest • Workflows across agencies who are having their film scanned, or are scanning themselves • Creating a technical guide or sample RFP for those using vendors to do their scanning (cross referencing FIAF & Presto Centre) • Metadata Capture • Cross Compatibility of Transforms • Testing ACES workflows - discussion of a shared testing environment/ resources / case studies • Other?
