Since 4K videos requires much on both the hardware and software to assure smooth playback, editing, uploading and sharing, the 4K video converter chosen to convert 4K videos needs to meet the higher standards. So, how to choose the best 4K video converter? The below 5 are the basic standards.

1. Great compatibility

Besides the power to recognize the 4096x2160 and 3840x2160 4K video resolution, the 4K video converter should have the ability to convert 4K videos from different sources to different resolution and formats. As a few devices, media players and platforms can handle 4K videos, converting 4K videos to 1080p or MP4/MOV format is the highest demand among users. So, it is possible to play with Windows Media Player/QuickTime, import to Premiere Pro, upload to YouTube, play on iPhone/Android, and more.

If you have iPhone 4K 30fps/60fps, GoPro/DJI 4K UHD, and Cinema 4K videos to process, you need a GPU-accelerated 4K video converter to help speed up the conversion process while releasing the burn of CPU.

3. High output quality

We choose 4K videos for their more pixels will provide more details. When we downscale 4K videos to 1080p or 720p, we don’t want to sacrifice their quality so much. So, the 4K video converter we choose should have something like “High Quality Engine” or “1:1 Copy” mode to keep the output quality as much high as possible.

4. Multi-functional

A good 4K quality converter should satisfy different purposes, such as 4K to 1080/720p, 1080p to 4K, any video to 4K, 4K video compression, 4K videos to any format, 4K videos to any device, and so on. So, it can fix 4K playback errors, editing problems, not uploading issues, and not sharing troubles.
