Hi
Can anyone tell me how to create the rays effect in the background of this?
http://www.istockphoto.com/stock-video-14417728-fashion-words.php?st=2403a1...

I want them to be slightly random and radiate out from the center.

CC LightRays? LightBurst?

Classic example of using Trapcode Shine. You can use a preset for the looks, apply it on a vertical white solid (you may want to apply a blur to that as well) and animate the "shimmer" and intensity. To variate the intensity and length of the rays you may want to try to create an animated white shape that changes (using a shape layer) and apply Shine to that. Keep the Blurred rectangular white shape behind the Shape Layer.

Thanks Ted!
So this effect cannot be achieved using built-in filters -effects?

Sure can! You can use any form of Radial Blur that allows you to use a 'Zoom' mode. I often use CC Radial Fast Blur (it's fast), but it only supports 8bpc.

In the example you posted, I would start by separating the pink rectangle into its own layer, adding Fractal Noise set to the 'Multiply' mode, then applying the radial blur. Set this layer to an additive mode, animate the evolution of the fractal noise and increase the radius of the radial blur.

You can adjust the fractal noise properties to change the size and frequency of the light rays.

It's somewhat different from using Shine, but can still give you a good result.

Or you can use CC Light Rays with Fractal Noise.
