DESCRIPTION
Abstract: Over the last decade, farms of Linux servers have powered the production of major motion pictures. Today, individuals can use Linux to produce and distribute video in numerous formats; for example, YouTube, iTunes, DVD, and Blu Ray. Linux is no longer a hobbyists' tool, but a powerful production system that can be custom tailored. However, setting up a system like this is not for the faint of heart. Video and audio encoding and compression schemes can drive one to drink. Editing software in Linux is not polished, but difficulties can be overcome with perseverance. I will attempt to show how to create a working production workflow using Fedora, Cinelerra and various open source tools to produce a video ready for YouTube, iTunes, DVD and Vimeo.
