Now, most cameras and phones are capable of taking 4K videos. Also, 4K video content has quickly occupied the market of streaming services, desktops, TVs, etc. 4K video is much clear than standard HD 1080p, but it takes up more storage and it’s hard to share.
This MiniTool Video Converter post will mainly talk about several 4K video compressors to help you reduce the file size of 4K video, so you can easily upload it to social media platforms or send it to others.
What Is 4K Video
Before going into the 4K video compressor, let’s learn what the 4K video exactly means.
4K video refers to a video with 4K resolution. In recent years, 4K resolution has gained great popularity in the film and television production industry and television display technology. 4K refers to a horizontal display resolution of about 4000 pixels, which means excellent image quality and an immersive visual experience.
4K video is also known as Ultra high-definition (UHD) video, and the standard for 4K resolution in the video/movie projection industry is 4096 x 2160 pixels, whereas the dominant 4K standard for television and monitors is 3840×2160 pixels.
Resolution determines the amount of detail in a video and is the main factor affecting the quality of the video image. Compared to full HD 1080p (1920 x 1080 pixels), 4K video has a resolution four times the resolution of 1080p video. Therefore, 4K produces better and crisper image quality than 1080p.

Why You Need to Compress 4K Video
Since 4K videos are now widely supported by many devices and have Ultra high-definition image quality, why do you still need to compress 4K videos? Here’re 2 main reasons.
1. Large File Size
With the rise of 4K videos, now, almost all new cameras and phones support shooting 4K videos like iPhone, GoPro, DJI, Canon, etc. 4K video brings you and your audience the perfect visual enjoyment and greatly increases the immersed sense, but it also means a large file size and takes up more storage space than 1080p video.
The specific file size of a 4K video depends on the parameters of your recording device, but there’s no doubt that 4K video file size is large. The higher the resolution of the video, the more pixels, the better the quality, and the larger the file.
Of course, 4K video will take up a lot of your storage space. Some people even need to purchase a larger external hard drive to store 4K videos.

2. Not perfect for sharing videos
Until now, almost all social media platforms like YouTube, Facebook, and TikTok don’t support direct 4K uploading. If you upload a 4K video, it will automatically compress it to a low quality. For instance, if you upload a 4K video to TikTok, it will automatically be downsized to 1080p that’s the maximum resolution for TikTok videos.
In addition, it might take a long time to process a 4K video while uploading. The processing time varies based on the video format, length, frame rate, and quality. For instance, a 4K video with a frame rate of 60FPS will need a longer time to process and upload.
Moreover, a large 4K video can’t be sent through email because of the file size limit. What’s more, 4K video may lead to issues like choppy playback.
In general, a 4K video is worth it if you have enough storage or that’s used for movie projects in high resolution. However, 4K is not perfect for small projects like online videos. That’s why you need a 4K video compressor to shrink the file size for easier uploading, sharing, and storing.

Understand Video Compression
Before we start discussing the best 4K video compressors, let’s go over the basics of video compression.
The goal of video compression is to reduce the size of the file because videos take up much space and the bandwidth is limited. More specifically, video compression is the process of reducing redundancy and storing information more compactly.
There’re many methods to reduce the video file size including changing the resolution, changing the format, and trimming a clip. In addition, the size of a video file can be shrunk by optimizing some video parameters like frame rate, bitrate, encoder, etc.
Generally speaking, MP4 using H.265 (HEVC) codec is currently the best-recommended video format because of its best compression efficiency, universal compatibility, and good quality. However, you should select the video format and encoder according to your needs. For instance, the accepted video format by most social media services is MP4 using the H.264 codec.
