batch convert DTS to Ac3 using ffmpeg

[Mishari]

Hi,

I'm looking for a way to run a script file in folder that contains mkv files and copy the video and subtitles and everything else as is except the audio, convert it to AC3, and saving the new files in the same name using ffmpeg.

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

the issue I'm facing is when I open the bat file is just open and closes immediately.

Try without quotes ( " )

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

The same issue

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

The mkv filenames maybe contains spaces.

[sekininsha]

you used a different type of opening and closing quotation mark (“ %%~dpnf-AC3.mkv ") (“” / "" (valid))

also check the filenames as it suggests ProWo ..

I recommend applying 'pause' to the end of the script ... so the cmd window stays open and shows you where the error ..

pause

Oh god what a silly mistake
Thank you so much, it was diving me crazy.

Thank you so much man! I also needed the guy below you to notice the different quote mark, but even after that I couldn't get this to work until I removed spaces from source files. I appreciate the hell out of you taking the time to answer questions like these. Even years later could come in handy. Thanks again!

Thank you so much man! I also needed the guy above you to know to remove spaces in source file, but even with that I needed to correct that Quotation mark from OP's script.
