Missing Source File from "New Features in After Effects CC"

I am doing the New Features in After Effects CC course which is part of the AE LaunchPad bundle. It is missing a source file in which the roto brush is used “ShortWalk.mov” - can anyone tell me how I can get the missing source file so that I can follow along with the tutor?
