Here is a ffmpeg script to copy a video from a NAS network drive to a local drive and remove unneeded audio in foreign languages.

copy %1 “D:\Temp\Temp\%~n1%~x1”
D:\Tools\ffmpeg\bin\ffmpeg -i “D:\Temp\Temp\%~n1%~x1” -map 0:0 -map 0:2 -acodec copy -vcodec copy “D:\Temp\Temp\%~n12%~x1”
del “D:\Temp\Temp\%~n1%~x1”
move /y “D:\Temp\Temp\%~n12%~x1” %1
echo pause
exit
