ffmpeg in bat file

[windranger]

I am trying to remove the sound stream from videos in a folder and save the new ones without sound in same folder with different names.
I am using a batch file comprising these commands:

set PATH=D:\movies folder
for %%a in %PATH%\*.MTS do ffmpeg -i "%%a" -c:v copy -an "%%~na.MTS" > errorlog.txt
pause

It doesn't do anything and the log file is always empty.

I tried this too
set PATH=D:\movies folder\*.MTS
for %%a in %PATH% do ffmpeg -i "%%a" -c:v copy -an "%%~na.MTS" > errorlog.txt

but same result. What am I doing wrong...?

Any hints appreciated

REM this would help:
set Folder="D:\movies folder"

Since your folder name has a space in it quotes are required. And PATH is the systems search path. If you set it to something else the system won't be able to find any program that's not in the current folder (for that instance of CMD.COM). Use a different name, like Folder (as suggested by butterw). Finally, the file spec in the FOR loop should be enclosed in parenthesis.

set FOLDER="D:\movies folder"
for %%a in (%FOLDER%\*.MTS) do ffmpeg -i "%%a" -c:v copy -an "%%~na.MTS" > errorlog.txt
pause

I don't know if this was your intentions, but all the new files will be created in the same folder in which the batch file resides.

Thanks jagabo and butterw, it's working now well.

One more issue- it saves the processed files in the same location where the bat file is.
I would like to save those files in a location of my choice, it could be for example the same folder
where the initial files are and a some suffix could be added at filenames of the new files.

Is there any possible syntax to do that..?

set FOLDER="D:\movies folder"
for %%a in (%FOLDER%\*.MTS) do ffmpeg -i "%%a" -c:v copy -an "%%~dpna (no audio).MTS" > errorlog.txt
pause

Thanks Jagabo, working now as expected.
