Gradient Background

One way to make your videos interesting is to have a dynamic background.

Here's a technique to add a nice touch to your videos. 

On the canvas, add a circle from the shapes menu.

Under the color panel, select radial gradient, then pick the color combination

You may also adjust the gradient on the circle by moving the indicator.

Resize the circle to cover the canvas.

Animate the circle to rotate and pick the right easing for you.
