Part 1: What is Video Resolution?

Video resolution (or video definition) is the measurement of data size in an image. PPI (Pixels per inch) is the indicator. It is noted that a video is a great combination of images. Therefore, the video resolution, in fact, is the image resolution. The image clarity determines the video resolution. Clearer the images are, higher the video resolution is. Of course, the bit rate of clear video will be large. That is stressful for network transmission and terminal play.

720P and 1080P are current video resolution. Along with the technology development, some high-tech players support 2K and 4K resolution. For example, movie theaters play 2K films now.

Part 2: About 720P, 1080P, 2K and 4K

720P (1280*720P) is the standard high definition. It refers to 1280 pixels of the horizontal resolution and 720 pixels of the vertical resolution. This standard HD usually appears in the video websites. A HD video, at least, should be 720P.

1080P (1920*1080P) means the ultra HD. It refers to 1920 pixels of the horizontal resolution and 1080 pixels of the vertical resolution. Now, most of video players support 1080P. Since a 1080P video contains more pixels, the video is naturally clearer than that 0f 720P. Beside, 1080P is the standard of many players, such as HD LCD TV, and the front projection, like plasma TV, D-LLA, SXRD and DLP.

2K is the resolution referring to over 2000 horizontal pixels. The mainstream 2K resolutions are 2560*1440P and 2048*1080P. In the digital cinemas, many projectors are 2K resolution. Some resolutions, like 2048*1536 and 2560*1600, belong to 2K, too.

4K is the resolution referring to about 4096 pixels in horizontal display. Generally, 4K is specific to 4096*2160. According to the usage environment, 4K can derive different resolutions, such as Full Aperture 4K (4096*3112), Academy 4K (3656*2664) and UHDTV standard (3840*2160).

Part 3: Differences among 720P, 1080P, 2K and 4K

Theoretically, the clarity increases from 720P to 1080P, 2K and 4K. A 1080P video is obviously clearer and more delicate than that of 720P. Although 2K is close to 1080P, it is still clearer. These differences are usually visible in the large screen. 4K performs best in visual effect because it contains the most pixels.

In fact, high resolution should not always be our target. For example, although a 4K video is very clear but the file size is extremely large. A 90-min 4K video is over 50GB, which is a great pressure of storage space, transmission and download. What’s more, the HD video has high requirements of the video player. We should select the suitable resolution for our device.
