Reports from the Field
A second glimpse of RAWcooked

What and how

A short demonstration of the last alpha release by Joshua Levy and Reto Kromer, followed by an informal Q&A session and light refreshments. This time, we will have computers running on the following operating systems:

  • Linux: Ubuntu 18.04 LTS, 16.04.3 LTS and 14.04.5 LTS
  • Macintosh: macOS 10.13.5 and 10.12.6, and OS X 10.11.6
  • Windows Subsystem for Linux with Debian 9.4 and Ubuntu 18.04 LTS

and LTO-6, LTO-7 and LTO-8 decks to play with.

When and where

Friday the 8th of June 2018, starting at 11 o’clock sharp, at our company AV Preservation by reto.ch in Écublens (a suburb of Lausanne, Switzerland). The admission is free, but an inscription is required, as the places are limited to eight, and our clients will have the precedence.

The missing piece of software for audio-visual archives

RAWcooked encodes so-called raw audio-visual data, like DPX or TIFF and WAVE or BWF, into the Matroska container (.mkv), using the video codec FFV1 for the image and audio codec FLAC for the sound. The metadata accompanying the raw data are preserved, and sidecar files, like MD5, LUT or XML, can be added into the Matroska container as attachments. This allows to manage these audio-visual file formats in an effective and transparent way (e.g. native playback in VLC), while saving typically between one and two thirds of the needed storage, and speeding up the back-up process on LTO cartridges.

When needed, the uncompressed source is retrieved bit-by-bit, in a manner faster than uncompressed sources directly stored on LTO cartridges.


Note

  • We are very unhappy that our generosity is often betrayed, as many of our materials are distributed without naming their origin. Increasingly, others are even shamelessly claiming authorship of our work, which is just disgusting behaviour. And that’s the very reason why some resources are no longer freely available, but have been moved to password-protected parts of our website.
