What does the number part of my video’s resolution actually mean?
Generally resolution in Videos you see—360p, 480p, 720p, or 1080p—represent the number of horizontal lines a video has from top to bottom. So, a 480p video is made up of 480 lines stacked one on top of another, with each line being 852 pixels wide. In other words, a 480p video has a resolution of 852×480 pixels.
For comparison, a 720p HD video has 720 lines that are each 1,280 pixels wide, meaning that it is more than twice as sharp as a the same video at 480p and can be viewed on a much larger screen.
