4K video is superior to 1080p video with 4 times pixels to capture more clear picture. However, when we try to play, edit or share online downloaded or camera/camcorder captured 4K video, we find that it is not less easily accessible and compatible than 1080p video.
Main reason to compress 4K to 1080p:
Most hardware do not support 4K video compression codec:
1080p video are compressed with the H.264 codec, which can be used by most movies and TV shows for streaming on the Internet. However, H.264 can not compress 4K video well. We need a new codec called H.265, which has double data compression rate to enable you compress 4K videos in small file size with the same quality to stream smoothly . However, the biggest problem is that the new H.265 codec has not widely adopted by most common media players, browsers and operating system.
