From box-office hits to home movies, Linux is ready, set, action.

From the operating system that gave you Lord of the Rings, Spiderman and pretty much every other film that's made these days, comes the Holy Grail of Linux computing: the home and small office video production pipeline. Unlike the object of Monty Python's ill-fated quest, however, thislong-sought treasure actually exists and is finally within reach.
The problem has been one of great frustration for many potential adopters: what do I do about my home videos, my hobby films, my presentation videos? These days, even the greenest newbies can bumble their way through assembling a video in the tinkertoy-like Windows Movie Maker, and Mac users are even better off. They have a properconsumer video editing application: iMovie.
Linux has, for years, been growing into a major standard in the Hollywood studio pipeline. A cursory glance at the CinePaint Web site reveals a catalog of films that could not have been produced on time or budget (if at all) without a Linux infrastructure. Without Linux, the Star Wars prequels would have had a different look, and there would have been no Lordof the Rings trilogy. From its early days on the renderfarms to its coming of age in Shrek, Linux has proved time and again its effectiveness, power and stability to the major studios.
None of which does the hobbyist user much good. Typically, filmmaking software for Linux is dearly bought; Eyeon's DFX compositing system, the most reasonably priced of any professional Linux-based compositingsystems, weighs in at a hefty $1,295 US per seat, and it's the least capable player in the field. The home producer historically sits in the worst possible spot: atop a free and exceedingly capable operating system that was powering the major motion picture studios, without any way to get in on the fun short of writing a lot of scripts and working from the command line a great deal.
During the lastthree years, that situation has changed. Although the situation is not yet ideal, the FLOSS end of the Linux universe now allows for a near-complete, end-user-oriented production pipeline. I know, because during the last four years, I've built up a production studio running entirely on Linux-with one gap in the pipeline-and I make my living using it.
Let's say you want to edit your brother'swedding video to produce a short film with an alien sitting in the audience as a guest. In the Windows and Mac worlds, several companies offer end-to-end commercial solutions that take you from acquisition through delivery-format authoring, covering (in no particular order) editing, titling, compositing, color correction, sound/score sequencing and DVD mastering. 3-D graphics applications are easilyobtainable from a variety of other companies, and for a variety of prices. However, the companies producing such software will continue ignoring the Linux market until their high-end customers force them to produce Linux versions of their software (as happened in the 1990s with the IRIX version of Photoshop).
Although it would be nice to have such tools, we're not going to get them. And, I canfinally say with confidence, the day approaches when we won't need them, either.
To get a home or small-office production studio running, you need most of the pipeline shown in Figure 1.(1-57)
