Video Resolution

Video resolution is a measure of the pixels that display on the screen.

What is video resolution?

Video resolution is a measure of the pixels that display on the screen. To determine video resolution, count the number of pixels that appear horizontally and vertically, also known as the aspect ratio.

This metric reflects how sharp and clear a video will look. The higher the resolution or pixel count, the more detailed and lifelike the video content appears.

What are the different resolutions for videos?

Videos can have one of several different resolutions. Here are the most common settings:

  • 480p (SD): Standard definition (SD) videos have a pixel count of 720 x 480. Older devices typically support SD.
  • 720p (HD): High definition (HD) videos have a pixel count of 1280 x 720. Many streaming services and gaming consoles support HD.
  • 1080p (Full HD): Full HD videos have a pixel count of 1920 x 1080. Newer TVs, desktop computers, laptops, and smartphones support Full HD.
  • 4K (Ultra HD): Also known as Ultra HD, 4K videos have a pixel count of 3840 x 2160. High-end TVs and monitors support 4K to show the sharpest and most lifelike visuals possible.
  • 8K (Super Ultra HD): Also known as Super Ultra HD, 8K videos have a pixel count of 7680 x 4320. This resolution offers an exceptional viewing experience and displays visuals with unparalleled detail. High-end entertainment systems and professional cinemas often support 8K.

What's the difference between 1080p, Full HD, and 4K?

To understand the difference between these resolutions, you need to know their pixel count and image quality.

Full HD and 1080p refer to the same video resolution (1920 x 1080 pixels). Compared to 4k, Full HD has a lower pixel count, which results in less detailed videos.

A step above Full HD, 4K has a higher resolution (3840 x 2160 pixels). Compared to 1080p, 4K videos appear clearer and more crisp.

When watching videos on smaller screens, you may not notice much of a difference. But on larger screens or with closer viewing distances, the superiority of 4K becomes apparent.

The higher pixel count present in 4K videos provides more lifelike imagery, more vivid colors, and more detailed visuals. As a result, 4K is ideal for viewing high-definition content such as nature documentaries or action-packed movies.
