How do they film scenes where there is 3d movement of the camera without people moving. Is this the same thing as second example where camera is moving in depth differently between things in foreground and background

Example:

Timestamp in video (but in general many parts of this music video) [https://www.youtube.com/watch?v=kTJczUoc26U&list=RDP1tI4VFMRmE&t=65s](https://www.youtube.com/watch?v=kTJczUoc26U&list=RDP1tI4VFMRmE&t=65s)

There are different techniques in different situations. Sometimes (like the matrix bullet time) there are a bunch of different cameras in different locations near each other. They take one frame from one camera, another frame from another, and so on.

Other times, the people just move really slowly (or stand really still) and they use a camera with a fast frame rate and move it quickly. Then they play it back at a normal frame rate so it makes everything look slow.

In the links you shared, some of them were probably things like models of poured liquid that are actually plastic, or maybe 3D models made with CGI. The second link looked like it was just a static picture that slid past the camera, with a separate background image. You can see that the people’s faces don’t change. But if you move a camera past a real face, there would be different parts visible at different times.
