Update: Samsung reached out to us to clarify that 8K videos aren’t limited by time but by file size. The phone simply divides the video into different files of up to 4GB in size but doesn’t stop recording until the user manually stops it.
Original story follows
The Galaxy S20, Galaxy S20+, and Galaxy S20 Ultra are the first smartphones ever to support 8K video recording. 8K videos are going to offer a lot of detail, so much so that you will be able to extract 33MP stills from them. Of course, that also means they will need more space, and we now have an official figure of how big these videos will be.
Each 8K video will take around 600 MB of storage per minute
According to Samsung, one minute of 8K video on a Galaxy 20 will have a file size of 600 MB. On a Galaxy S10+, a minute of 4K video takes around 340 to 350 MB of space, and since 8K videos have four times as many pixels as a 4K video, it’s impressive that an 8K video will only use 600 MB per minute. But that’s still quite a lot, and a lot of processing power would be required for 8K video recording, which is why the Galaxy S20 will only record a maximum of 5 minutes per video.
Furthermore, each 8K video will be shot at 24 frames per second, which is the industry standard for Hollywood movies as well (though higher frame rates have been used in some movies, such as The Hobbit). Naturally, there’s no option to record 8K videos at 60 fps on the Galaxy S20, as both the Exynos 990 and Snapdragon 865 can only go up to 30 fps for 8K videos.
