Video Digitization
DVA-Profession is a complete solution for digitizing video for archival purposes. It manages the whole workflow, ranging from digitization to analysis, generating preview images and a preview video (MPEG), manual quality control, documentation of all process metadata and the final deposition of the files on a digital mass-storage. All steps of the workflow are designed and optimized for an economic operation and preparation for long-term archiving (for further information see "documentation").

On June 23, Mr. Antonio da Silva, a representative of the UN Audiovisual Archives visited the Mediathek Headquarters in Vienna to learn about the practices and procedures applied to audio and video digitization and digital preservation. In particular, to learn more about DVA Profession system and workflows. "The technical visit allowed the UN to learn about best practices and procedures being used by Mediathek's team for digitization and preservation. It was a great opportunity to see a hands-on demo of the open-source approaches. The UN is looking for future partnerships with national audiovisual preservation institutions, such as Mediathek, creating and applying sound tools and best practices in the AV preservation area."

Digitisation and Digital Preservation Challenges at the BBC

Recently, there was a webinar by Tom Heritage and Richard Wright from BBC about "Digitisation and Digital Preservation Challenges at the BBC".
The video of the presentation is available online on Vimeo (thanks to PrestoCentre). We were happy to find out that the features and requirements of BBC's "Ingex" tape ingest system, described by Tom Heritage, are also covered by DVA-Profession:
  • Use of a lossless codec. Across the whole workflow in realtime.
  • Audio uncompressed.
  • Metadata written in standardized format (METS, LoC MD-profiles)
  • File checksums
  • Frame checksums
There are slight differences, though. Some even advantageous:
  • Reduced data storage:
    Using FFV1 as lossless video codec greatly reduces the costs and allows having more copies for absolute data integrity.
  • Content can be retrieved fully or partially directly from the storage across the whole institution. Independent of underlying technology 
  • Metadata stored separately (=allows updating/augmenting the AIP. Checksum-safe)
  • Multiple copies in 3 different pools: 2 RAID HDD cluster filesystem + 1 LTO tape robot.
  • AVI as container. Less interoperability or accessibility problems than with MXF.
  • "Minute segements": Difficulties with handling very large files are bypassed, by simply storing the video in segments with 1500 frames each.

It might be noteworthy, that we are currently working on our new long term storage + management system. This allows handling cases described by Tom Heritage and Richard Wright as "currently not solved".

Ferry machines go virtual
19. August 2013 04:25
In order to ease and speed up the installation of new ferry background processing computers and new DVA-Profession installations, we are currently working on moving the ferry setups into Linux-KVM based virtual machines.
In order to ease and speed up the installation of new ferry background processing computers and new DVA-Profession installations, we are currently working on moving the ferry setups into Linux-KVM based virtual machines. The current VM-host is running on Debian 7, and the benchmarks look very good so far: There seems to be no noticeable performance loss due to virtualization. We are currently working on 2 setups in parallel:
  1. Classic setup with Debian 6
  2. New setup with Debian 7
These setups will be made available as Linux-KVM images in QEMU's "qcow2" format. This format should is easily convertible to raw format, so it can also be used with other virtual machines like Virtualbox, VMWare etc.
