Dots – Grid Transition
I need to create a grid-like layer of slightly random dots which cross the screen in a transition. I realize this is quite simple, but I’m having trouble manipulating the dots properly with particular, and think an expression could really make it easier.
Ideally, I would like the dots to appear from left to right by adding the dots (rather than using keyframes to actually move them). The result is, a bunch of dots being added from left to right (not moving) covering the screen for a moment before disappearing screen-right.
The problem with particular is that, while the grid dots can be randomized well, the perimeter of the grid is pretty much fixed. I haven’t been able to, say, extend any of the rows of dots out ahead of the rest (like fingers on a hand of grid dots).
I can solve that by breaking the grid down into single rows and duplicating those screen-crossing rows into the “broken” grid I’m looking to create, but then I can’t get the right randomness on the back end of the dot trail.is anyone familiar with an expression i can tweak for this?

Is this what you need ?
step 1:
Animate a gradient from left to right in an oversized comp.Step 2:
Add Horizontal Turbulent displace:Step 3:
Precomp, Crop and add a Mosaic Effect:Step 4:
Multiply or Stencil Luma, a grid of dots (I made this with Generate->Circle and Stylize->Motion Tile)
Step 5:
Finished. -
Yes!
Thank you filip. So clear.
This looks like it’ll work. -
Right now, the trails are actually all of equal length, just scattered.
This can be easily mimicked by overlaying some blurred out fractal-noise over the original gradient:

Oh wow. You just saved my life sir. 😀
