I don't know if there's a pre-existing site that will do it, but you could do this with FFmpeg and therefore FFmpeg.wasm. A brief search [1] indicates that it would likely be about the combination of the right filters. Ostensibly, you could put those filter options into the FFmpeg.wasm demo app [2] (scroll down) and get your video out.

Talking about online animation tools ...
Does anybody know a site where one can create "zoom in animations"?
I mean you upload an image, select the point where the animation should zoom in and get a "fly into the image" animation.
