The content is interesting but when you get onto the masking I have no clue as to what the top LH window is..(it seems to be UV/image editor) Think you should have taken some more time in explaining the set up better..How you have customized VSE windows to perform these functions..... feel the need to go to YouTube and check out how to do masking in VSE. Also 2.79 does not seem to have the "Normals" adjustments in the texture panel.....
