Part 1: What’s The Best Video Resolution

What is Video Resolution?

Since more and more people prefer to watch videos with high quality, the video resolution becomes higher and higher. However, many people do not understand the resolution well. For example, what is 4K/2K/1080P/720P? What about their differences? How about the resolutions of mobile phones, 4k TVs, DVDs, video recorders, and different video files? How to convert the resolutions, the aspect ratios, and the formats between videos?

Video resolution indicates the precision of a video in unit size. When you enlarge a video, you can see many tiny areas of illumination called as pixel, the basic element of a video.
Resolutions and pixels have a tight connection with each other. For example, the resolution of a video is 1280*720, which indicates that there are 1280 pixels in horizontal and 720 pixels in vertical.

What is Video Resolution

The resolution, one of the most important elements of video quality, determines the video image precision. Generally speaking, in the case of two videos in a fixed size, the video with higher resolutions contains more pixels. As a result, the video will be more delicate and of high quality.

720P, also called as “high definition”, generally means the 1280*720 resolution. It refers to a horizontal display of 1280 pixels and a vertical display of 720 pixels, which is a mainstream resolution in video websites. Since it is the lowest standard of high definition, it is also called as standard HD. A video whose resolution is below 720P is not HD.

1080P, means 1920*1080 resolution, called as “full high definition”. 1080P refers to a horizontal display resolution of 1920 pixels and a vertical resolution of 1080 pixels. As for most of videos display devices, it looks quite clear because it provides enough pixels.

2K, also called 2K resolution, refers to a horizontal display resolution of over 2000 pixels. The mainstream 2K resolutions are 2560*1440 and 2048*1080. Many digital projectors adopt 2K resolution. 2048*1536 and 2560*1600 are also included in 2K resolutions.

4K, also called 4K resolution, refers to a horizontal display resolution of approximately 4,096 pixels. Mostly, 4K means 4096*2160 resolution. Due to the application scope difference, various resolutions are derived from 4K, such as 4096*3112 (Full Aperture 4K), 3656*2664 (Academy 4K), and 3840*2160 (UHDTV standard).

What’s the best video resolution for home video?

The best video resolution for your home videos is one that’s clear, crisp, and easy to watch. Standard-definition videos are limited to 720 pixels on the width and 480 pixels on the height, which isn’t a lot. High-definition videos have a resolution of 1,080 pixels on the width and 720 pixels on the height, or 2,160 pixels on the width and 1,080 pixels on the height. You can even find videos in 4K or 8K resolution, but those resolutions are best suited for professional use. Standard-definition videos are only 720 pixels on the width and 480 pixels on the height. Two ways to convert your old videos to high-definition are recoding the video or using a video editing software to upscale the video.
