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.
This last week I've been trying my hand at a bit of DVD authoring and I thought I'd pass on everything that I've found out! A couple of the most useful tools are command line based, hence the title, but I'm also going to talk about a fantastic GUI that brings these bits and pieces together. To my horror, just as I sat down to write this I discovered Mitch Meyran had just posted a very similar blog entry! This post, however, is a bit more command line based and HOWTO-like in structure.
