Very recently, we've received several emails inquiring how to play 4K MKV video without quality loss. Some people wonder what 4K MKV is and the differences between 4K MKV, 1080P MKV and average 4K video files. Actually, it's very simple to understand.

A video player that could play MKV videos can also play 4K MKV video theoretically, but the video quality differs between different MKV video players. In this post, we would like to introduce you 2 ways to play 4K MKV video files without quality loss.

Also, you can play various videos, photos and music stored on USB to be connected to PS4 Pro media player. Even though the MKV format has been included in the supported file list of PS4 Pro, many users have encountered various issues like this. "I tried to play the MKV movies on PS4 Pro, but I came to see the message during the playback ‘there was a problem playing this item’ on the PS4 Pro.", or some other messages like "The MKV playbacks can’t be played smoothly on PS4 Pro and the MKV files always crashed during the playback."

Why does this happen? The MKV is the supported format of PS4 Pro that does not mean all the MKV files could be played. Just as you know, MKV format has lots of video and audio codec information within the file. Only certain MKV files with some specific codec information can be played on PS4 Pro, like video: H.264/MPEG-4 AVC High Profile Level 4.2; audio: MP3, AAC LC, AC-3 (Dolby Digital).

If your current MKV files don’t meet the above requirements, then you would fail to open them with PS4 Pro. In such a case, what can you do to play the MKV files correctly? You can try to convert the MKV to other formats that are much more common and compatible with PS4 Pro, like MP4, or AVI etc. In order to complete the video conversion process, you need the help of Leawo Video Converter. The detailed steps would be shown below.
