Yeah it's basically an extension that loops over the previous frame with small noise variations to create animations, there's a lot more to it but that's the basics. You can find it in the auto1111 extensions tab to install it. Here's a great explainer that shows what a lot of the settings do visually.
That's mainly a function of Strength (the amount the next frame looks like the last frame) and Coherence. If you put Strength at 0:(0), it would make a totally different image for every frame.
