External Mattes in DaVinci Resolve

Lately I’ve been having to utilize external mattes a lot in commercial work.  If you’re not familiar with them, they’re extremely handy and you’ll wonder how life ever existed without them.  Although the workflow is fairly simple, it was recently brought to my attention that not many people are aware of the external matte capabilities in Resolve.  They can help you completely transform a shot that would otherwise be unfixable.  While it involves some glorified rotoscoping behind the scenes, you’ll be extremely happy with the newfound flexibility.  I made this quick video to showcase external matte workflow.  I hope you find it useful!
