If you're interested in getting a really deep understanding of Vegas (or Movie Studio), DVD Architect (Studio and Pro) and Sound Forge, have a look at my new courses at lynda.com.

Essential Training for Vegas Pro 12 goes deep into the tools in the program. And, because the interfaces are so similar, about 95% of the course also applies to Movie Studio.

The Sony Vegas Production Workflow takes you through the process of creating and editing a project in Vegas (or Movie Studio), cleaning and polishing the audio and Sound Forge and then outputting the finished piece as a DVD or BluRay using DVD Architect Pro (although a large part of it will also work for DVD Architect Studio).

Each has some free lessons in addition to the full course available to lynda.com subscribers.

Thanks for checking them out!

Steve, where is the Audacity course? I only see one Audacity course on Lynda.

Oops! My mistake. I teach Sound Forge, not Audacity. Sorry.

Thanks. I saw an Audacity course but you weren't listed as the instructor so I was confused. You cleared it up.
