Standard Definition (SD) has a resolution of 720 pixels wide and 480 pixels high (480p) while High Definition (HD) has a wide resolution of 1,920 pixels and a height of 1,080 pixels (1080p). In addition, there are more than 3000 pixels in 4K videos.
And video quality is based on video codecs and video bitrates. The general consensus is AVC / H.264 which is one of the best video codecs currently to get higher quality video with a smaller size. Btw, video formats (such as AVI, MP4, WMV, etc.) Only containers, which are not criteria for evaluating video quality. In addition, video bitrate is also a very important factor. Usually, the higher the video bitrate, the better the video quality.
