How does video resolution typically affect the quality of an image?

Video resolution refers to the amount of detail an image holds, and it is primarily defined by the total number of pixels in each dimension that the video displays. The greater the number of pixels, the higher the resolution, which generally leads to a clearer, sharper image with more detail. This is crucial for visual clarity, especially on larger screens, where lower resolutions can result in a pixelated or blurry image.

In contrast to the other options, brightness is not directly related to resolution; rather, it relates to the display technology itself. Frame rate pertains to how many frames are displayed per second and is separate from resolution, even though both affect overall video quality. Audio quality is distinctly different from video resolution, as it deals with sound capturing and reproduction rather than visual detail. Therefore, understanding that video resolution directly indicates pixel quantity is fundamental to comprehending image quality in the context of video production.
