Mark Spencer talks about adjustment layers in Final Cut Pro X. He goes over with Steve Martin how with adjustment layers, you can apply different affects to a group of clips without having to apply the affects to each clip individually in FCPX.

As a bonus, Ripple Training has created this adjustment layer title effect for you to use. You can access the effect by going to: http://www.rippletraining.com/using-the-adjustment-layer-title-in-final-cut-pro-x.html
