DaVinci Resolve

They reckon something like 70% of Hollywood movies are colour graded in DaVinci Resolve.  You used to have to pay a fortune for a standalone box with Resolve installed, but now you can get it for FREE!  You can visit the Blackmagic Website and download it so you can work at home.

More than this, Resolve is no longer just a Colour Grading application.  It's now a full-blown post production suite, since Blackmagic purchased Fusion (compositing) and Fairlight (audio), and incorporated seamless editing, compositing, colour grading and audio in a single program.

The videos below are introductory, and walk you through DaVinci Resolve in broad terms.  It's a good place to start.
