Internet searches turn up the same or similar problem in Windows 10 as far back as 2016, but this is the first time I've come upon it. The problem lies strictly in the file details that Windows displays, and it's the same in File Manager and FreeCommander, so it appears to be rooted somewhere in Windows itself with the 1803 update. Video playback is not affected in VLC or Pot Player. i have some problem with xmedia recode latest version 圆4 for some test i need to convert my original video file mkv to mp4 with xvid codec and audio on mp3 VBR original video is 1920x800. That seems to narrow the problem to the file extension. And if I convert MKV to MP4, the file data appears. There are also several presets available for devices. This occurs whether I create the file new as MKV, or if I convert an MP4 to MKV (I use XMedia Recode, copying everything rather than converting). The format tab allows you to choose the container type (AVI, MKV, MP4, etc.) and the video and audio codecs (H.264, XVID, AAC, MP3, etc). But if I use MKV, some details are missing, including frame width, frame height, frame rate, data rate, total bitrate, and the thumbnail image.

Using codec h.264, if I use the MP4 container, I get all file details. Version 1803 doesn't show some file details for files with the MKV extension.
