It's a really powerful tool, and one of the better open-source projects.
Since I started using it a couple years ago they really kicked into high gear with adding features and improving it.

And that's awesome, I actually used Ubuntu Studio and did a whole video on it about using Linux for music production. If you're going to use Kdenlive though I wouldn't use the one that Ubuntu provides in their repositories because it's usually outdated. It's always best to get the latest Kdenlive App-Image from the Kdenlive website.

What's the deal with the "!PIZZA" thing? I noticed a lot of people doing that from the Deep Dives community.
