Lens Flare

I made my own “Ray of Light” flash style animation

Now I want to add a little Lens Flare.

I have been searching for some tuts. Anyone know of a good one?

Although I have managed to piece together this title animation, I am still a newbee. I tried to recreate a subtle star burst on my own and the moving transparent discs of a lens flare, but I had to remove what I tried.

I want to add a tiny star burst. I tried the only method I could think of which is to make a series of overlaping thin rectangles and rotate them in in place overlaping. But this looked bad. I could not find out how to make the ends taper to points.

Another thing to add is a circle – not a solid circle but just a little edge colored a subtle purple . How do I do this and make sure it is centered where I want it to be?

And I want the whole thing to kind of spread apart in the time line like you see when a camera is hit by a blinding light then moves to the side.
