Part 1: What are the differences between SD and HD, Full HD, 4K, 8K

Video quality is an important part of a viewer’s live streaming experience. Blurry images, pixelated faces or objects can all detract from the message of the video. It’s useful to know about video resolution — specifically around SD vs HD vs 4K vs 8K — and how it impacts the quality of a streaming video.

And the video resolution is all in the pixels. Pixels are individual units of color information. Thousands or even millions of pixels may combine to constitute a visual image. Generally speaking, the more pixels per given amount of screen real estate, the sharper and more detailed the image will appear.

The number of pixels displayed on a screen is commonly expressed as resolution. Resolution is presented as (number of pixels in a row) x (number of rows). Common screen resolutions, and hence video resolutions, are 720 x 480 (SD), 1280 x 720 (HD), 1920 x 1080 (Full HD), 3480 x 2160 (4k), and 7680 x 4320 (8K). SD stands for the standard definition that the video stream is in lower resolutions like 144p, 240p and 360p. HD stands for high definition. HD refers to the high definition with a resolution of 720 or 1080 pixels and so on.
