Linux Video Production: the State of the Art
A Few Thoughts on Sound
A video pipeline deals with a particular sort of software, but it's not the whole story when it comes to media production. The process of sound design for video is at least as involved as the video side of the equation.
In brief, you'll need a sound effects editor, a synthesizer, a mixer, a recorder and a scoring program. I've found the greatest productivity out of the fewest number of programs using Audacity, Ardour and Rosegarden in tandem, while keeping a handful of synths (like TerminatorX) around for use in a pinch. The process of sound production for a video or motion picture is a story in itself that deserves telling, but not today. In the meantime, a full discussion of the sound tools available for Linux can be found in the excellent article by Dave Phillips in past issues of Linux Journal (the September 2004 issue has a good technical overview of many contenders, and the September 2005 issue has an extensive article on Rosegarden).
Open-Source Blue Screening
Of special note in the open-source compositing field is the newcomer MatteLab (www.nccn.net/~w_rosky/evan/evan/programs/mattelab/index.html), a Java-based one-task utility that is very nicely designed and written by 16-year-old high-school student Evan Rosky. Although, at the moment, it does not support multipass keying, it is the best keyer I've yet seen in the open-source space on Linux. Outputting as it does to transparency-enabled PNGs, it allows for multiple instances of single passes to be run on the footage without quality loss, and when used in conjunction with Blender or Jahshaka for compositing, it is a very powerful tool indeed.
Dan Sawyer is a freelance director/producer running the backbone of his small studio on Linux. He has been an enthusiastic advocate for free and open-source software since the late 1990s, when he founded the Blenderwars filmmaking community (www.blenderwars.com). Current projects include the independent SF feature Hunting Kestral (www.blenderwars.com/kestralmannix) and The Psyche Project, a fine-art photography book centering on strong women in myth.
Practical Task Scheduling Deployment

One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
