What Is Video Resolution?

Resolution refers to the number of distinct pixels each dimension can display. Video resolution is usually expressed as width × height, with the value given in pixels. For example, 1024 × 768 means this video has 768 lines that are each 1024 pixels wide.

Common Types of Video Resolutions

4320p: 7680×4320

7680×4320 pixels is known as 8K or 4320p. It offers 16 times more pixels than the regular 1080p FHD or Full HD resolution. However, right now, you can only see 8K on expensive TVs like Samsung and LG.

2160p: 3840×2160

2160p, a very large display resolution, is commonly known as 4K or UHD (Ultra-High Definition) resolution. 2160p offers four times the resolution of 1080p. 4K resolution mainly exists in the digital television and cinematography industry.

1440p: 2560×1440

1440p is commonly known as QHD or Quad HD resolution. Typically, you can see it on gaming monitors and on high-end smartphones. 1440p is four times the resolution of 720p HD or HD ready.

1080p: 1920×1080

It is usually known as FHD or Full HD resolution. It is suitable for HDTV high definition video with a widescreen aspect ratio of 16:9.

720p: 1280×720

720p is usually known as HD or HD Ready resolution. Most television channels broadcast at this resolution. 1080p is developed based on 720p.

Standard Definition (SD)

The most popular standard resolutions are 640 x 360 and 640 × 480 for video, and 720 × 480 and 720 × 576 for DVD.

Reading here you might think that the higher the resolution the better. However, in fact, to get a better viewing experience, you need to consider the video resolution as well as the aspect ratio.

For instance, if you put a 720p (1280 x 720 pixels) video in an iPhone 6 Plus, you might find there are some black bars. Therefore, it is necessary to change video resolution to avoid the black bars.

If your video has black bars, don’t worry as you can find answers from this post “Tutorial: How to Remove Black Bars – Windows Movie Maker.”
