Boxed Children - FREE After Effects Preset

Boxed Children is an After Effects Preset that allows you to surround layers by a box by simply parenting layers to the box in question.

Create a rectangle shape, run the preset with the rectangle selected, then parent any amount of layers you want to it and watch the magic happen.

You can modify the box settings from the Effects panel.
