How to Downscale 4K Video to 1080p on Mac and PC

4K (Ultra HD) has a resolution of 3840 x 2640, with four times as many as pixels as 1080p. You can easily get 4K contents from sources like YouTube or shoot 4K by GoPro, Yi 4K+, DJI drones and many affordable 4K cameras from Panasonic, Sony, Nikon, etc.

However, it's not easy to play, edit or share 4K videos, compared to 1080P, so many people will convert 4K footage to 1080p. This tutorial will show you how to convert 4K to 1080p on Mac and PC.

Why Downscaling 4K to 1080p?

If you want to experience real 4K content, you need a 4K monitor. Normally, 1080p is good enough for watching on your laptop or mobile. Also, 4K video file size is huge, for example, a minute of 4K 30fps video takes up 375MB, while 1080p at 30fps requires only 130MB. By compressing 4K files to HD, it definitely saves space.

Besides, there are requirements for uploading video to social media platforms like video format and file size limit. If you want to post video to multiple social media, downscaling 4K to 1080p/720p MP4 is a very good option.
