    I have a script below which was done for me to blur subtitles, using ffmpeg. is there a way to make the blurred subtitles more fine. like smoother. if so what is needed in this script or can be added

    Code:
      @setlocal
    @echo off
    @echo "delogo parameters script"
    
    @set xx="Unknown"
    @set yy="Unknown"
    @set ww="Unknown"
    @set hh="Unknown"
    
    @rem folder where ffmpeg.exe is located
    @set FF=C:\ffmpeg-3.4-win64-static\bin
    @set PATH=%FF%;%PATH%
    
    @set filename=%~1
    
    @rem video quality settings
    @set vq=25
    @rem audio bitrate
    @set ab=192
    
    :new
    @cls
    @echo .
    @echo .
    @echo   Old delogo=x=%xx%:y=%yy%:w=%ww%:h=%hh%
    @echo .
    @echo .
    @rem delogo filter settings
    @set /p xx="Enter X - the top left corner coordinate of the subtitle: "
    @set /p yy="Enter Y - the top left corner coordinate of the subtitle: "
    @set /p ww="Enter W - the width of the subtitle to clear: "
    @set /p hh="Enter H - the height of the subtitle to clear: "
    @cls
    @echo .
    @echo .
    @echo      delogo=x=%xx%:y=%yy%:w=%ww%:h=%hh%
    @echo .
    @echo .
    @echo "Are you OK with above delogo filter parameters"
    
    @choice /c:yn /M "Press Y for Yes to preview, N for No and return to start."
    @if errorlevel 2 goto new
    @if errorlevel 1 goto start

    @echo .
    @echo "Start ffmpeg with delogo filter parameters?"
    @echo .
    @echo .
