One of the special problems with managing a multimedia project (versus a text-based software project), is that there are often links to external data files which can get broken when you try to move the files around -- such as you might do when re-factoring the source code to make it more navigable. Three programs that we use extensively in the Lunatics project present this problem, and each requires slightly different handling. These are Inkscape, Blender, and Audacity. I have never found a compact guide to keeping the links straight in these programs, so I'm going to write one here.
If you've been following my column for the last year or two, you already know that "Lunatics" is the free-culture animated science-fiction series that we are creating with free-software applications like Blender, Synfig, Audacity, Inkscape, Gimp, and Krita. We are finally crowd-funding for our pilot episode "No Children in Space" on Kickstarter. If we get funded, this will be a major step forward for free-culture and free-software in the media industry. Come check it out, tell everybody you know, and/or get a copy on DVD or other cool stuff from the project!
Not so much a software book as a book on theory and technique of sound processing, "Sound Effects, Tips and Tricks" is a concise look at what can be done with good signal processing software. I found the book interesting, occasionally frustrating, and enlightening. In the end, it mostly taught me to have a better understanding of what I didn't know -- but that's useful.
Home recording is not that hard or expensive to do, and Audacity provides a great tool for recording and editing dialog. I recently got the equipment together to do decent voice recording for our "Lunatics" video project. Total cost was under $150.00 for a condenser USB microphone system, and the sound is a tremendous improvement over my previous attempts. Now our biggest challenge is the room acoustics. So far, we're having a lot of fun recording dialog.
Audacity is one of my favorite free software applications, and it has really improved over the years. This book covers the latest features in the 1.3.x series, which is expected to lead directly to the version 2.x Audacity. The book covers more than just Audacity, though. In the process of covering several different uses, it also discusses everything from hardware equipment selection to copyright and business problems that may come up in a project. Overall, it's a good read and a good introduction to Audacity, audio recording, and audio processing.
Ogg Vorbis and Ogg FLAC (the Ogg stream version of the Free Lossless Audio Codec) are popular free-licensed and patent-free codecs for handling sound. These are the formats I'll be using in a complex Ogg Theora video file that I am creating as part of my "Lib-Ray" experiment in creating an alternative format for distributing high definition video. In order to do this, I'll need to solve several technical challenges using the FLAC command line tools, Audacity, and VLC, which I'll demonstrate here.
You might think that a good program is all about good programming. But for a number of applications, the barrier to success isn't programming at all. Some of the most interesting projects nowadays -- speech recognition, for example -- rely on machine-learning from databases of information. It's not enough to write free software for these applications, we have to also provide that software with the right data. Contributing to these projects is needed from a much larger group of people, but it also can be very easy to do.
Previously, I demonstrated creating an animatic using Kino. That was an interesting exercise, but Kino is not really up to that kind of job. Blender, on the other hand, has a very nice "video sequence editor" built into it, and it turns out to be very well adapted for this kind of task.
I found a useful sound effect in an online video from NASA which replaces an earlier temporary sound I used in a scene soundtrack for the Lunatics pilot, "No Children in Space." I'm going to extract the sound from the video (with VLC), cut out the sound I need, clean it up, and insert it into an existing sound mix (all with Audacity). This should give you some insight into using Audacity and a VLC on a real project.
An animatic is a kind of a rough sketch for a film. It's not really meant to be an artform in itself (although some reach that point), but it is rather intended to be enough information for the filmmaker to make intelligent production decisions. It also must be cheap and easy, since effort that goes into the animatic will not appear in the final film. I have not yet fully decided what tool is right for doing the animatics for Lunatics, so I'm doing some experiments with different tools in order to decide. In this column, I'll create an animatic for a short sequence from the pilot.
In my recent article on QDVDAuthor, I skipped over the task of making a videoloop for the main DVD menu. Here I'm going to show you how I did it. The goal is a short loop of video that smoothly transitions through five different video segments and back to the beginning again. The audio is shaped and lowered to make it more or less even and not so distracting (loud menus can be obnoxious if they are left running).

For me there is nothing quite as relaxing as the sounds of the beach. The slow crashing of waves and the gentle lapping of water in the tide pools really helps me find my inner calm. Of course, I could do without the smell of rotting fish carcasses, the constantly screeching gulls and the looming threat of melanoma. So I decided to create my own virtual beach experience using some free sound clips from the internet and the free software package called Audacity. I’ve got all the relaxation without the annoying dead fish, dive bombing birds and sunburn.
