Tutorial showing how and why to use the invisible split-screen/spit-comping technique that David Fincher's editors (Angus Wall & Kirk Baxter) have become known for.

Also, I've compiled a bunch of interviews with Fincher's editors concerning this technique if you want to check them out: www.mediafire.com/view/j1229xdk3fd8b2b/Invisible_Split-Screening_Interviews_&_Research.pdf
