Reports from the Field
A third glimpse of RAWcooked

The missing piece of software for audio-visual archives

RAWcooked encodes so-called raw audio-visual data, like DPX or TIFF and WAVE, using the video codec FFV1 for the image and audio codec FLAC for the sound, and wraps it into a Matroska container (.mkv). All 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 greatly speeding up the backup 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.

What and how

A short demonstration by Reto Kromer of both the current 18.10.1 release and the improvements made in the development branch, followed by an informal Q&A session and light refreshments. We will have computers running on the following operating systems:

• Linux: Debian 10.2 and Ubuntu 18.04.3 LTS
• Macintosh: macOS 10.14.6 and 10.13.6
• Windows: Subsystem for Linux (Ubuntu 18.04 LTS) and Terminal

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

Note that most probably this meeting will be bilingual German and French without translation.

When and where

On Friday the 21^st of February 2020, starting at 11 o’clock sharp, at our company AV Preservation by reto.ch in Écublens (a suburb of Lausanne, Switzerland).

As usual, the admission is free, but an inscription is required, as the places are limited to six at our small facility, and our clients will have the precedence.

Notes

• We request the participants to wear the provided FFP3 masks and to use our alcohol-based hand sanitiser.
• 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.
