• Batch file to add separate audio file to MP4 file [closed]

  30 janvier 2021, par MrRoso

  I have a couple of video files (MP4) with audio in France.
Video1.mp4, Video2.mp4, Video3.mp4, ……
In the same directory, I have the same couple of audio files in English (m4a).
Audio1.m4a, Audio2.m4a, Audio3.m4a, ……

  


  The command

  


  ffmpeg -i "Video1.mp4" -i "Audio1m4a" -map 0 -map 1:a -c copy "Out.mp4"


  


  to add the audio file to the Video file works fine, but I need to do this for each video and audio file manually.

  


  I want to do this in a batch file, like this :

  


  @Echo off
for %%i in (*.MP4) %%j in (*.m4a) do ffmpeg -i "%%i" -i "%%j" -map 0 -map 1:a -codec copy "/new/%%~nI.mp4"


  


  But I get the follow error message :
"% j" cannot be processed syntactically at this point.

  


  Also the new batch file ends in an error :

  


  @Echo off
for /F tokens=i,j %%i in (*.MP4) %%j in (*.m4a) do ffmpeg -i "%%i" -i "%%j" -map 0 -map 1:a -codec  copy "/new/%%~nI.mp4"


  


  Error Message :
"i" cannot be processed syntactically at this point.

  


  Has someone a batch file for me, which is working ?

  


  Best regards

  lavf/file : file_check : Handle file URLs that start with "file :"
  Handle the URL analog to file_open, it may contain a "file :"
  
  prefix. Skip it. Make access checks to file URLs starting
  
  with "file :" work.
  Fix part of ticket #3249.

  I try to convert a sequence of pictures to video file. 
But I get from ffmpeg the response, that no such file or directory

  



  Does someone have a solution for it ?

  



  My command line :

  



  ffmpeg -r 1/5 -start_number 0 -i "C:\Users\USER\Desktop\Pictures\%3d.png" -c:v libx264 -r 30 -pix_fmt yuv420p C:\Users\USER\Desktop\Pictures\out.mp4


  



  The error :
