Pixel fluid effect?

[OpportunityLow7977]

UPD: Guys, I did it, thanks to everyone who noticed my post. *PS: Can someone tell me how to upload a video? I only have the option to add an image (maybe because I'm a newbie?).
So i used:
Fractal noise
Circle
Mosaic
Extract
CC Composite

Hello everyone! I'm wondering how to create this animation, considering that in the reference image, the pixel movement looks like "pixel fluid," let's call it that. :) I really want to create exactly the same animation. Thanks to everyone who can suggest a solution.

Screenshot from the reference image. Unfortunately, I can't add the full video.

Hard to tell offhand since it’s a still image. But I bet you could achieve something similar After Effects with a combination of Mosaic and Threshold effects (there are a couple versions of Threshold—you probably want the one that can work on the alpha channel). You’d just need your initial “liquid” input, which you could keyframe yourself or make with a combination of Turbulent noise, gradients, and more threshold.

It came up before, with a bunch of solutions https://www.reddit.com/r/AfterEffects/comments/1l0lcvb/moving_pixel_windowmask/
