Duplicate audio file before converting it

[Mishari]

Hi,

I have below script working fine but I need it before converting DTS audio file duplicate it.
Let's say I have MKV file contains three components.
vidoeo
DTS
Subtitle

what I want after running the script these four components
video
AC3
DTS
subtitle

FOR %%f IN (*.mkv) DO C:\Users\MS141\Desktop\ConvertDTStoAC3\ffmpeg\bin\ffmpeg.exe -i %%f -map 0 -vcodec copy -scodec copy -acodec ac3 -b:a 640k %%~dpnf-AC3.mkv

Try the -map options like in this thread:

The command line in that thread didn't work. But a small modification does:

FOR %%f IN (*.mkv) DO ffmpeg.exe -i "%%f"    -map 0:v -c:v copy    -scodec copy    -map 0:a -c:a:0 copy    -map 0:a -c:a:1 ac3 -b:a 640k    "%%~dpnf-AC3.mkv"

Thank you it's working but with one small issue is that it keeps converting even if it's already finished from the batch it goes all over again.

The problem is you're creating new MKV files in the same folder -- the batch process sees the new files and and tries to process them too. Put the new files is a different folder.

Okay, I tried to do it with in ~dpnf but it was going wrong every time forgive me I'm not filmier with commands.
Could you please tell me how to put the output in a new folder inside the original folder ?

Something like:

MD AC3
FOR %%f IN (*.mkv) DO ffmpeg.exe -i "%%f"    -map 0:v -c:v copy    -scodec copy    -map 0:a -c:a:0 copy    -map 0:a -c:a:1 ac3 -b:a 640k    "AC3\%%~nf.mkv"

That will create a subdirectory called AC3 and put all the new files in that folder (same name as original).
