Best MP4 Video Converter for Windows (10/11)/Mac to Convert Video to MP4 or Vice Versa
The recent news reveals that PS 4 Pro's media player adds support for 4K MP4 video, from which we see an obvious truth: MP4 now contains UHD (ultra high quality) video, although it is not the real point of focus.

But note that H.265/HEVC is not widely acceptable at present, so your MP4 converter Windows 10 might be used to convert 4K MP4 to H.264/MOV/AVI/WMV, etc.
