I want to add cover art to all the MKVs in a folder












0















I'm trying to batch add cover art to all my MKV files in Windows using Batch scripting but I can't. My file structure is like this:



Video1.mkv
Video1.jpg


Both video and image have the same filename, the only difference is the extension.



I've tried the following command:



FOR %%f IN (*.mkv) DO (
mkvpropedit.exe "%%~nf.mkv" --attachment-name "cover" --attachment-mime-type
"image/jpeg" --add-attachment "%%~nf.jpg"
)


It's weird how this command works for other apps and it's not working for MKVPropedit.



The result is:



Error: The file '%%~nf.jpg' could not be opened for reading: open file error.


My jpg files are not corrupt so I don't really know what that error means.

          You should use a different variable letter in your FOR command. The letter f is one of the pathname format letters (the complete list is a, d, f, n, p, s, t, x). For example, use G as shown here:



          FOR %%G IN (*.mkv) DO (mkvpropedit.exe "%%~nG.mkv" --attachment-name "cover" --attachment-mime-type "image/jpeg" --add-attachment "%%~nG.jpg")


          According to SS64.com G is a good choice because it provides the longest run of letters that don't conflict with any of the pathname format letters:




          %%G is a good choice because it does not conflict with any of the pathname format letters (a, d, f, n, p, s, t, x) and provides the longest run of non-conflicting letters for use as implicit parameters.
          G > H > I > J > K > L > M




          Further, if you're running this directly from the command prompt, you need to use single % characters, not double, as shown here:



          FOR %G IN (*.mkv) DO (mkvpropedit.exe "%~nG.mkv" --attachment-name "cover" --attachment-mime-type "image/jpeg" --add-attachment "%~nG.jpg")
