This tutorial is all about the basics of node-based compositing. Rather than doing a ramble on the interface and explaining every button, I decided to work with a practical example. This way, you'll get a real-world project with the software to get you started quickly.
This tutorial is mainly meant for people who already have a little bit of experience with applications such as After Effects of Photoshop, and working with render passes.
The software used for this tutorial is Natron. Why Natron, you might ask? Well, the interface and shortcuts are very similar to Nuke, but Natron is open source and thus free. So it's a great way to get acquainted with a node-based workflow without spending money. You can also use it on commercial environment, so you're not limited to a student or personal learning edition.
Don't get me wrong, Nuke is a wonderful application to work with and even has a free learning edition with a few limitations. One of those limitations is that it's not meant for commercial work.
EDIT: The workfiles have been updates to work with Natron 2.0.
As always, enjoy the video and don't hesitate to ask me questions!
