This "Light Sweep" effect can be added to video, shapes or titles.
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.
I would personally like to thank you, sir! It seems silly, but I have been LONGING for a quick and easy way to generate a light sweep effect to my .png files/ logos. What a great product you have created, and I truly appreciate it!
