Twinkling Stars

Post by Kathy Engelhard »

Is there an easy way to make twinkling stars? I tried by cycling 4 different white dots on a black layer but they looked like tiny jumping or shooting stars. :lol:
Has anyone done this already?
Thank you.

The trick with twinkles is to avoid a blinking. You have a basic star, just a little white dot, and only every second or so it brightens up a bit. Duplicate that layer, place it elsewhere, and change the timing and loop length so all twinkles will happen at different frames. Voila.

I've done it by erasing pinpoints into the background of a night sky and then creating a pan background behind the sky which is painted with streaks of semi-whites on white (or yellowish and even a pink here and there). I've used the same effect to achieve shimmering reflections in the water of objects on shore. The pan background of course is a secondary project combined with the primary project through the KeyFramer in the FX stack. When you drag a painted background like this behind the pin pricks you get a very convincing effect without ever seeing any repetitions.

Thank you Slowtiger and Paul. I am so glad that I asked because, I would have never thought of doing it either of the ways that you both suggest.
I recently finished studying the pan method in the manual and practiced doing it a couple of times.

I don't know about making a loop because I've only used the loop button when I play my project. Could you please give me more info or directions for making a loop?
Thank you both for such great help! :D
