In video, what does the term "resolution" refer to?

The term "resolution" in video specifically refers to the amount of detail an image holds, which is typically expressed in pixels. This definition encompasses the width and height of the image, such as 1920x1080 pixels (Full HD) or 3840x2160 pixels (4K). Higher resolution means more pixels are used to create the image, which generally leads to greater detail and clarity. This is crucial in video production and playback, as it directly impacts the viewer's experience and the overall quality of the visual content. Understanding resolution is vital for professionals in the AV industry, as it influences everything from equipment selection to content creation and distribution.
