        else
            mv "${file}" "${filename}-[${vid_width}x${vid_height}][${vid_codec}].${extension}"

        fi
    done
}

This bash function appends video width, height & codec to all video files that match provided file extension. It uses ffprobe to detect video properties. The default file extension is mkv.
There's also dry-mode option available. Just pass -d followed by the file extension to only print the rename command without executing it.

Examples:

Rename mode:

renamevideofiles
Renamed vid1.mkv to vid1-[1280x720][h264].mkv
Renamed vid2.mkv to vid2-[1280x720][vp9].mkv
Renamed vid3.mkv to vid3-[1280x720][av1].mkv

Dry-mode:

renamevideofiles -d mkv
Dry-mode enabled
mv vid1.mkv vid1-[1280x720][h264].mkv
mv vid2.mkv vid2-[1280x720][vp9].mkv
mv vid3.mkv vid3-[1280x720][av1].mkv
