Footage
Video, Image
noun, の adjective
You see reflections of images on a screen, and the image reflections are moving! That means this is footage, or video.
映像 refers to images in various forms of visual media. While it's most commonly used to describe moving images in videos or films, it can also refer to mental images — those pictures or scenes that come to mind, reflecting personal memories or imagination.
