What does video resolution mean?
Video resolution refers to the number of pixels in a video image. Specifically, it is the number of pixels that a video has in a certain direction (usually horizontally and vertically). These pixels together constitute the basic unit of the video image, which determines the clarity and detail expression ability of the video.
Video resolution is usually expressed as the number of pixels of "width × height", such as 1920 × 1080, which is what we often call 1080p high-definition video resolution. In this example, 1920 means that the video image has 1920 pixels in the horizontal direction, and 1080 means that there are 1080 pixels in the vertical direction.
Different video resolutions correspond to different clarity levels. Generally speaking, the higher the resolution, the richer the details of the video image and the higher the clarity. Common video resolutions include 720p (1280 × 720), 1080p (1920 × 1080), 4K (3840 × 2160), etc. With the development of technology, there are now higher resolution video standards, such as 8K (7680×4320).
Video resolution is not the only criterion for measuring video quality. In addition to resolution, factors such as video frame rate, encoding method, color depth, etc. will also affect the quality of the video. Therefore, when evaluating the quality of a video, it is necessary to consider multiple factors comprehensively.
