Question About .mkv Output

[Mikey january11]

When I use OBS to record an mkv file, I noticed that when I go to Properties --> Details, it doesn't show any codec information. The resolution, video bitrate, audio bitrate, etc. are missing. However, the file plays fine in VLC and I can see some of the codec information on VLC as well.

Why isn't OBS embedding this information or why isn't Windows 11 showing it under Properties? Is there a way to fix this?

That's the explorer properties dialog. It has only minimum support for determining codec information. Only the most common file formats are detected, only the most common (usually obsolete) codecs, only the most common resolutions and other things. Many of these properties are not just one property you read in in instant from a file header. They need to be extracted by reading the file, and this is probably considered too stressing by the Windows Explorer devs.
If you're interested in sophisticated codec info from the Explorer context menu, check MediaInfo: https://mediaarea.net/en/MediaInfo

Thanks so much for the response. MediaInfo was what I needed!

Could you please to me why the properties dialog will display the codec information for an mp4 file I produce from OBS but not an mkv? I don't think I yet have a clear sense of why this happens.
