How to create stars like this?

I tried to follow this tutorial using the similar FX in VEGAS Effects, but it doesn't work

@datoaliffalex I recommend watching the video at a slower speed and pausing if need be. Immediately from comparing your screenshot with the video, you have your layers in a different order. If there is a specific step you're getting stuck on then post some more information in your next comment so hopefully users can help.

Right-click your fractal noise plane and select "Make Composite Shot." Choose to move all effects with the plane.
Then you can turn the fractal plane off.
In Vegas Effects, effects that have Source Layers (like Set Matte) reference the source layer in it's "RAW" state - before effects are added. basically the Set Matte isn't seeing the animated noise. Embedding the Fractal in it's own Comp "bakes in" the noise so that the Set Matte properly sees it.

@TheBenNorris @Triem23 I've follow exactly in the tutorial, I even make a comp on the fractal noises, but the matte just don't "matte" base on the fractal noises.

Could have sworn that I came up with a way to make stars twinkle a while back. I'm gonna try to find the project because I don't remember what I did.

Oh OK, I used the particle simulator to create a starfield, the I used atomic particles on top of it and animated the opacity random up and down.

@Dimipapa any tutorial for that?

Hmm well it worked but the effect was maybe too subtle. So another way is get a make a starfield, not with too many stars, then duplicate it and change the seed, do this like 3 or 4 times. Then use the flicker effect, change the amplitude to .40 and the frequency to .50 and I think that creates a nicer twinkle. do it on like 2 of the starfields and change the seed for each effect. If you cant make a starfield I think there is a good tutorial in this video

Just to be that guy... 😁 Stars only twinkle when seen from an object (planet) with an atmosphere, I believe. Now. The nebula in that thumbnail might suffice...not sure. But generally in space not so much.

im assuming the stars will be used as a night sky not a space scene.
@datoaliffalex Oooh I actually put the heat distortion effect on, and dialed back the settings, THIS IS THE WAY.
