I've created a few FCPX plugins and made them available to all. I hope you enjoy them.
There's MOODY - a grading plugin.
CHANNEL SPLIT - an RGB channel split effect based on scaling the channels independently, including the BW Ghost ;-0. A split based transition soon.
LIGHT LEAK - bitmap based light leak emulation.
GOOD LETTERBOX - A letterbox with selectable ratios and the ability animate the vertical offset.
If you use the plugins, please send me a link to your vids.
Just drop the whole folder (VLFfx) into your ~Movies/Motion Templates/Effects folder.
