Move Shapes shows how to create a write-on effect using gradient strokes in Ae.

This new tutorial from the Move Shapes channel (Peter Arumugam) walks through how to create a nice-looking gradient stroke in After Effects animated as a write-on effect.

The tutorial shows how to create a stroke path with the gradient by applying blend effects in illustrator and creating a smooth animation in after effects. Adobe After Effects has some updated stroke workflows for motion graphics work, like the ability to taper the stroke quickly.
