Thus, HEVC is the commonly used codec for 4K videos, which is not widely compatible with computers and other software. To make the 4K video smaller, a codec with a high compression rate is needed. Almost all the computers and software support 1080P video.Īnother problem of the 4K video is the video codec. Thus 1080P video is the best option for these situations.
Besides, when you try to back up the videos to the cloud, you will find it very time-consuming and space-consuming. You can refer to the below picture for the reference of videos video taken by the iPhone.Įven though the space of our devices like mobile phones and computers is getting bigger and bigger, 4K video files can still be a great threaten, especially for some old computers with low configuration.
A 4K 60 FPS video coded in HEVC for one minute long taken by iPhone is about 400 MB, and it’s about 90 MB for 1080P 60 FPS video. No even a worry to zoom in to see the image details of 4K videos.Ĭorrespondingly, the video file size of 4K video is much larger than 1080P videos with the same bitrate, same length, and same codec. That is to say, there are four times of pixels to render one same picture of 1080, making it clearer than 1080P videos.
In a resolution, 4K 3840 x 2160 video is exactly four times of HD/1080P 1920 x 1080 video. It’s no doubt that the quality of 4K video is higher than 1080P video’s.
