By Cecilia Hwung | Last Update:

Summary: Here is a roundup of 9 best 4K video converters given their performance, features, availability, and ease of use. Depending on your goal when seeking a 4K video converter, these tools can help you to fix 4K playback errors, solve editing hiccups, swap containers without re-encoding, resizing, or compressing while maintaining the best quality.

With iPhone shooting 4K 30fps/60fps, GoPro and DJI capture 4K UHD videos, Cinema 4K, 4K 4:3, and platforms streaming 4K content, consumers have more access to 4K videos than ever. But when people tries to work with 4K videos, exporting from iPhone to TV and computers, playing back on Windows/Mac, editing in Premiere, iMovie, DaVinci Resolve, things become complicated.

Below are some of the issues that a dedicated 4K video converter can help you with. You can also skip these, find the detailed description of each tool below and pick one that caters to your needs.

4K video converter solves these issues and beyond:

  1. Compatibility concerns: Dealing with playback errors on TV, Windows/Mac, upload correct 4K format to YouTube and edit smoothly in DaVinci Resolve, etc. Converting 4K MKV to MP4, MOV for playback, or to ProRes (intermediate codec) for video editing.
  2. 4K video stuttering or lagging: Some devices fall short on 4K HEVC, 4K 10bit, or 4K HDR videos. Plus, iPhone that shoots VBR (variable frame rate) 4K video can be problematic for editing software. 4K converter can change codec, convert VFR to CFR, and manage other codec settings.
  3. Convert 4K to 1080p: Downscaling 4K videos to lower resolution to save storage space, go for quick sharing where quality is less a matter.
  4. Convert videos to 4K: Using a 4K converter to upscale 720p/1080p videos to 4K in certain scenarios. Some users are trying to do so not because they want to fake a 4K video. Instead, the specific use case can be, you are editing on a 4K timeline with footage from various resources, and you prefer to convert everything to 4K to streamline the process.
  5. Convert 4K to best quality at smaller size: This is handy for 4K files from iPhone, GoPro videos, DJI, and DLSR cameras. Depending on your settings when recording the video, the file size can be unnecessarily large. With a dedicated video processing tool, you can convert 4K video and make it smaller – no matter you decide to keep the original resolution or downscale – without losing quality.

When choosing a 4K video converter, there are several factors to consider. Besides the issues mentioned above, you will also want to pay attention to the 4K resolution of your original video, and check whether the converter supports the 4K video resolutions at various aspect ratios (4K 16:9, 1.9:1, 4:3 etc).
