How to Convert/Downscale 4K Ultra HD Video to 2K/1080p HD Video?

4K content, 4K video and 4K resolution are coming to everyone's daily life since the increasingly number of tablets, mobile phones, computers and TVs are able to play 4K video movies. 4K (2160p) resolution's images are around 4,000 pixels wide and it means more pixels. More pixels means more information and more information means sharper and more clear pictures – but don't forget one thing, the higher resolution also definitely needs more "space" and "time". That is to say, more space to save your 4K movie video and more time to download a 4K video are much-needed.

Therefore, it's not a wise choice for users to watch or download 4K video on portable devices. And now, here is a solution for you – convert 4K to 2K/1080p resolution. 2K resolution is a generic term for display devices or contents having horizontal resolution of approximately 2,000 pixels. Digital Cinema Initiatives (DCI) defines 2K resolution standard as 2048×1080. After downscaling 4K to 2K/1080p, you can enjoy high definition videos on mobile phones and tablets in a hassle-free way and won't be bothered by the insufficient memory error any more.
