Adding a twinkle effect

[Mike Clasby]

You can do a pretty good quickie of the TV commercial tooth twinkle with this.

Overview:

A white solid with a star mask, rotation and opacity keyframes with CC Radial Fast Blur in the Add mode.

Details:

Add a white solid (Ctrl Y).

Draw a 4 point star with the Pen tool the size you want the twinkle (a little smaller actually).

Set Opacity keyframes (T reveals, click the stopwatch) at zero, then 3 to 5 frames down the timeline at 100, then another 2-5 frames set to zero again.

Set rotation (R) keyframes with the same timing.

So you know have a very sharp edged star that appears and rotates on a tooth then disappears.

Now ad the effect “CC Radial Fast Blur” the defaults should work fine, except you need to center the “Center” with the middle of the star.

Set the Blending Mode of the layer to add.

Tweak keyframes and effect to taste.

Thanks Mike

That was just the ticket. Thanks for your quick reply, I guess that I just add this forum to my favourites.

Thanks again
