hi Reino,

I entered -c:v copy in command line as you suggested see below:
FOR /F "tokens=1,2 delims=," %%b IN ('ffprobe -v 0 -show_entries
stream^=bit_rate^,sample_rate -of csv^=p^=0 "%arquivo%"') DO ffmpeg -i
"%arquivo%" -af
loudnorm=linear=true:I=%vluf%:LRA=11:tp=%vpeak%:measured_I=%II%:measured_LRA=%ILRA%:measured_tp=%ITP%:measured_thresh=%IT%:offset=%TO%:print_format=summary
-c:v copy -map 0:0 -acodec mp3 -b:a %%c -ar:a %%b
"C:\Users\%username%\Desktop\Convertendo_lufs\%arquivo%"

The batch runs loudnorm and also copies the image to the output file, but
It turns out that at the end of execution, the message appears:

Input #0, mp3, from 'Lobão - Cuidado!.mp3':

Other detail:
When I see the converted file on the windows screen, the image (COVER) does
not appear as in the original file, ex:
In the original file I see the cover image of the song, in the converted
file only the mp3 icon appears and not the cover image?!!

thanks
