4K is indeed good in quality and it’s an enjoyment to watch the 4K videos on your TV and computer. However, it’s not an occasional situation when you find your PC can’t play the 4K video files with the default media player, which would make you really frustrating. What to do? You know MP4 is the mostly used format, and your player supports it, therefore, converting the 4K video to MP4 might be your first thought.
Well, that’s not wrong. In most cases, the 4K playback problem can be solved after you converting it to MP4. But that does not always work if you don’t understand the principle. Two main factors may result in the 4K videos playback failures. One is large file size, another is incompatible video/audio codec. The size of 4K video is extremely larger than HD, SD videos’ with the same length of content, since one frame image of 3840X2160 4K is precisely 4 times of 1920×1080 HD in pixel. And the mainstream 4K video is encoded in HEVC, VP8/9, AV1, etc. Currently, the compatibility of these codecs is not high as the common ones.
That is to say, you need to either compress 4K videos or decode and encode the 4K videos in another common codec such as MPEG, H.264, etc. In a rare situation, you may need to do both. But, none of this can be a trouble with WinX Video Converter, which can compress and convert 4K video to MP4 at once.
