Linux Scripts

A collection of small scripts used to speed up everyday CG/VFX work on Linux. They cover video conversion, EXR sequence processing, file management and various utility tasks.

Requirements

• ffmpeg
• ImageMagick
• GNU parallel
• OpenImageIO tools
• OCIO environment variables

Installation

For Debian-based Linux distributions, install the dependencies via:

sudo apt-get install ffmpeg imagemagick parallel openimageio-tools

Set the OCIO environment variable according to your colour configuration.
