• How to convert .mov files to .mp4 (H264) using ffmpeg using windows .bat file ?

  13 juillet 2013, par kheya

  I have a number of different video files (mov, avi, flv, mp4, 3gp, wmv) in a folder.

  I need to use a batch file that will convert all mov, avi, wmv, 3gp files in the folder
  Also I need to skip any flv, mp4 files

  I have this command, but it gives error and generates 0 size files :

  for %%F in (*.mov) do ffmpeg.exe -i "%%~fF" -vcodec copy -acodec copy "%%~dpF\%%~nF.mp4"

  The above line just tries to process mov files. I get same result for avi files.

  I want to keep the file name same. I get the file names correctly but it gives error :
