MovIm is developed since late 2018 by Reto Kromer, who first presented it publicly in 2019. It is a new video codec, specifically designed for both conservation and restoration purposes, and is actually an enhancement and a replacement of his YCoCg and the MSMI video codecs. This work has been directly inspired by a discussion he had with Tommy Aschenbach at the AMIA Conference 2018. However, he wishes to acknowledge also the inspiration given in various occasions by Claudio Weidmann, Jim Lindner, Carl Eugen Hoyos, Peter Bubestinger-Steindl, Jérôme Martinez and Michael Niedermayer.

We use the unofficial FourCC «MovI» for this video codec.

The openMovIm package contains the libmovim C library, implementing the MovIm video codec, and its associated command-line utilities movimenc, movimdec and movimplay, as well as the openmovim Bash command−line interface to libmovim, allowing to encode, decode, play and analyse virtually any moving images. The package is released under a 3-Clause BSD License and is provided «as is» without warranty or support of any kind. The source code will become freely available, as soon as a public beta not requiring special user’s skills will be released. A PDF of the current man page is available. It contains, en passant, additional information about the implementation.

Alpha Release

The library is currently used mainly as a plug-in for the Diamant-Film restoration suite. Our inner circle can already install and test an alpha, which comes with a few short test files, by running the following command in the Terminal:

brew install avpres/formulae/openmovim

The Homebrew installation has been successfully tested on x86_64 architectures running on the following operating systems:

  • Linux: Ubuntu 18.04.1 LTS and 16.04.5 LTS, and Slackware 14.2
  • Macintosh: macOS 10.14.3 and 10.13.6
  • Windows 10: running Debian 9.5 or Ubuntu 18.04.1 LTS
