Why background swaps are hard on a GIF
The subject moves, so a clean swap means separating it from the background on every frame and keeping that separation stable. Done by hand it is slow and tends to flicker at the edges, which is why most people never bother for a GIF.
Letting the editor do the separation removes the tedious part.
Changing it from a prompt
Bring the GIF, describe the new background, and aigif re-renders it, keeping the subject and replacing what is behind it across the whole clip. You can keep adjusting the prompt until the scene is right.

- 02
describe the background
Say the new scene, e.g. 'put this on a beach' or 'make it a city at night'.
