Examples of when changing changing aperture in the same video clip?

Could you please give me example of situations when changing the aperture ( that means the depth of field, and exposure, right? ) is necessary during shooting the same video clip?

Do you mean the "Hitchcock Zoom":

It's also called the "Dolly Zoom". If you google those terms, you get many links about it.

Thanks for your response. No, I didn't mean that. In a continuous shot, if you move from a scene to another with a different lighting condition, you may need an aperture change. I just came to know that changing the lighting condition itself can be another way to solve the problem. I have to think, though, if that can be done in all circumstances.

Going from a dark room outside into direct sunlight?
