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?

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

Changing aperture can greatly impact the depth of field in a video clip. A wider aperture (smaller f-stop number) will result in a shallower depth of field, making the subject in focus stand out more from the background. On the other hand, a smaller aperture (larger f-stop number) will result in a deeper depth of field, making more of the scene in focus.
Yes, changing aperture can also affect the overall exposure and lighting in a video clip. A wider aperture allows more light to enter the camera, resulting in a brighter image. Conversely, a smaller aperture allows less light to enter, resulting in a darker image. It's important to adjust other settings such as ISO and shutter speed accordingly when changing the aperture.
Changing aperture can be used to create different moods and effects in a video clip. For example, using a wider aperture can create a dreamy or romantic look, while a smaller aperture can create a more serious or dramatic look. It can also be used to draw attention to specific elements in a scene or to create a sense of distance or closeness between the subject and the viewer.
Yes, there can be some challenges when changing aperture in the same video clip. One potential challenge is maintaining consistency in exposure and lighting throughout the clip. It's important to pay attention to the lighting conditions and adjust other settings accordingly when changing the aperture. Another challenge can be maintaining focus on the subject, as a wider aperture can result in a shallower depth of field and make it more difficult to keep the subject in focus.
To effectively change aperture in a video clip, it's important to plan ahead and have a clear understanding of the desired look and effect. It's also helpful to have a tripod or other stabilizing equipment to ensure smooth and steady shots when adjusting the aperture. Additionally, it's important to practice and experiment with different apertures in different lighting conditions to become comfortable with how they affect the overall look of the video.
