This effect works the same as the FCPX "Aged Paper" effect, but with a choice of textures or a drop zone.
It has been setup to work with all SD, HD, 4K & 5K resolutions at all available frame rates from 23.98 to 60fps in FCPX.
It also has a PDF file inside the folder. This folder, as downloaded from the link below, should be put inside a "Custom" named folder in your "Effects" folder inside your "Motion Templates" folder in your "Movies" directory.
For those of us that think visually, it might help if we could see a before & after pic or something to help us get a clearer understanding of what your plugin does. Sure we all understand "aged," but visuals help sell the concept.
I had preview video's for everything, but I deleted them all. When I get time I'll start putting something quick together.
I tried my hand at putting tutorial video's together, but my accent is a nightmare for anyone to understand. If anyone feels like they fancy doing any for any templates I post I know I'd welcome them as a reply.
