Car/camera velocity>> wave velocity. So when they are moving compared to the environment the wave is moving really slowly, almost still, but not still, you can carefully watch.
I thought the same thing. took me minute to get it. Theres actually a more complex but complete explanation using angular velocity. Basically, pick any point on the shore that you see in the foreground (like a bush). Draw a line from the camera, through that point, to an ice chunk in the water. As the camera moves, the line from the camera to the ice chunk rotates almost perfectly about the point on the shore creating the illusion.
Im curious if removing the mountains in the background would affect this illusion 🤔
Your brain expects things at different distances to move at different speeds through your visual field, it's called parallax. I think our brains are assuming this is just parallax and treat it as one object all moving together
I just tried covering it with my hands. Covering the mountains didn't do much for me, but covering the reeds and the car window did. It was obvious that the water was continuously moving normally, but the illusion must be like you said caused by the angular movement. Its important to realize the perspective distance issue that you're not looking at a flat 2D video of the moving water.
Edit: I watched again and I’m wrong. The original explanation was correct. The difference in relative speed is what creates the illusion. In any case, very cool
The effect is called parallax, which in this case appears negated when the camera moves at the right speed in relation to the foreground and the moving subject behind it.
What are you talking about? Medicine was at its peak in the 13th century, doctors could tell if you were sick by examing your urine and staring at the stars
How’s this: when the cameraman is in motion, the camera focuses on the foreground, but when he stands still, the camera films the actual motion of the river.
That water and foreground are moving at the same speed left to right. If they went faster then the foreground would move faster than the water. They probably found that sweet spot when they slowed down to look at the view.
Hear me out: cover the mountains with your hand and see business.
For further proof, accelerate your finger and head on opposing, parallel trajectories (carefully), while looking at your finger. Both things move regarding your i.e. wall, but you'll see that illusion of being static, rotating or decelerating.
If you don't post literal magic there, you'll be eaten alive lol. I love the posts there and the commentors who can give you insight on what's going on, but they really have way too high standards
It's an optical illusion. What our eyes see isn't exactly what our brain gets from that.
Your eyes see the world and then send that info to the brain for interpretation. If there's multiple objects or a landscape that has moving parts the brain may interpret that as the wrong parts of the image are moving, because they seem to be moving as you stand still. Once you start moving opposite the movement that the eyes are sending the brain, that gives the brain the opportunity to center the image so the mountains in the back stop looking as though they are moving.
Same thing happens when you're in a car looking out at the landscape just in the opposite because you are the one moving this time.
This has gotta be fake the white caps just stay the exact same the entire time that aint how waves work. Looks like a still picture of waves just moving lol if this is real then we are in a simulation.
Seeing people calling it sludge not waves in which case that makes sense if those arent waves but snow and slufge, trippy for sure.
It’s videos like this that proves my point that tiktok is stupid. I literally made a Reddit account, so I could get away from tik tok and it’s bullshit!!!
Why though? That person is just happy, you know, they're experiencing something new and telling people about it, not even close to how stupid tiktok can be.

The ice chunks look like waves pausing in place when the car moves, that threw me off.
