4K MP4 is a robust multimedia container that is just like other video formats like MKV, AVI and MOV with capabilities to hold multiple content including video, audio, pictures and subtitles under the same container. This media format offers a very high content compression ratio, while maintaining the same quality of video and audio content thus it is more suited for delivering HD Videos (HD MP4) or 4K Videos (4K MP4) quality content.

However, because the codec is so new, users may still encounter issues one or another while playing them back on Windows 11/10. In that case, we would recommend converting 4K MP4 files to a format that is well compatible with Windows 11/10 first, such as H.264 MP4 and WMV. Here’s a tutorial guiding you through the process of transcoding 4K MP4 files to Window 11/10 preferred video.
