The fundamental principle of video resolution
Before jumping into the nitty-gritty specifics of SD resolution and HD resolution, let's look at other factors of video resolution such as the resolution frame rate, and "progressive" instead of. "interlaced" scan techniques.
Pixel size
What is video resolution? It's all measured in pixels.
Pixels are the unit that are used to represent information about color. Thousands, even millions, of pixels can be combined to produce visual images. In general, the greater number of the screen's real space is occupied by pixels, higher the quality the image.
The number of pixels that appear on the screen is usually measured as resolution.
Resolution = (number of pixels per row) * (number of rows)
Common screen resolutions (hence resolutions of video) include:
- SD video quality: 720 x 480
- HD 720 resolution: 1280 x 720
- HD resolution 1080 (full HD resolution size) resolution: 1920x1080
- 4K resolution: 3480 x 2160
Frame rate
The higher the frame rate, the more smooth the video will appear. The two most common frame rates are 30 frames per second and 60 frames per second. On the lower part is 30 frames per second, the speed that a human's eyes can sense the that a frame is paused between frames. The more high end is 60 frames per second. When video clips are viewed at 60 frames per second generally appear better.
The Progressive version of the system vs. interlaced scanning
There is a possibility to view resolution, which follows by letter "p" or "i." Without being too specific these letters simply represent the way in which video will be scanned.
- "p" signifies progressive " p" is a reference to " progressive," which provides a more precise representation of the display of each Pixel in the way it is supposed to be.
- The " i" means " interlaced," this is a possible method that uses shortcuts to display every line within an image.
The progressive format will appear better although interlaced could not appear as sharp, but it can be broadcast easier.
What exactly is SD video?
SD is shorthand for standard definition video and has the aspect ratio 4:1. While we've made progress in the past, the 4:3 TV display and broadcast SD still has value for live streaming.
SD refers to what's commonly thought of as the base-level resolution that is used in streaming and broadcasting. While you can stream with lower resolutions such as 144p, 240p, or 360p, you probably won't be in a position to stream below SD at the 480p resolution.
Does SD stream more quickly than HD?

What exactly is HD video?

- "Full HD" is usually referred to as 1080p HDwhich is also commonly referred to as 1080 video and is used more regularly for higher resolution, high-quality streaming and video.
