 The basic principles of resolution of video

Before jumping into the nitty-gritty details of SD resolution and HD resolution, let's look at some other key components of video resolution: pixel size, frame rate and "progressive" vs. "interlaced" scan techniques.

Pixel size

What's the resolution of a video? It's all measured in pixels.

Pixels are units of color information. Millions, perhaps thousands, of pixels combine to create visual images. In general, the greater number of pixels per screen real estate and the higher resolution the picture will appear.

The amount of pixels displayed on display screens is typically expressed as the resolution.

     Resolution = (number of pixels within a row) * (number of rows)    

Common resolutions for screens (hence video resolutions) include:

  • SD video quality: 720 x 480
  • HD 720 resolution: 1280 x 720
  • HD 1080 resolution (full HD resolution size) Resolution: 1920 x 1080
  • 4K resolution: 3480 x 2160

Frame rate

The faster the frame rate, the smoother and more fluid the movie will appear. The two most common frames are 30 fps and 60 frames per second. On the lower side is 30 frames per second, the speed at which a human eye detects the pause between individual frames. On the higher end is 60 fps. When videos are played at 60 FPS, they are generally more appealing.

The Progressive version Vs. interlaced scanning

You may occasionally notice a resolution followed by either a "p" or "i." In the absence of getting too deep, they simply represent how the video will be scanned.

  • "p" stands for progressive " p" is a reference to " progressive," that is an more precise description of how the display is displayed of each pixel as it should be.
  • "i" stands for "interlaced. " i" signifies " interlaced," that is a different technique that utilizes shortcuts to display every other line in an image.

Progressive will look better, whereas interlaced will often not look as crisp however it is broadcast more efficiently.

 What exactly is SD video?

SD stands for standard definition video and has an aspect ratio of 4:1. While we've made progress in the past from 4:3 television display and broadcast the SD format is still useful in the world of live streaming.

SD can be referred to as the basic resolution that broadcasters and streamers use for their. Although you are technically able to stream with lower resolutions such as the 144p, 240p, or 360p, you probably won't need to lower the resolution below SD with 480p.
