  $info = pathinfo($file) ;
  $out = "$info[’dirname’]/ss_$info[’basename’]" ;
  exec("ffmpeg -i ’".$file."’ -i ’".SS_ROOT."".$ss->settings[’watermark_image’]."’ -filter_complex ’overlay=main_w-overlay_w-10:main_h-overlay_h-10’ ’".$out."’") ;

• How do i add multiple sound effects (mp3) to a video (mp4) at any given time in the video ? [closed]

  25 octobre 2023, par StudentProgrammer

  I am trying to automate my editing process. I have a video.mp4 with a given length, a folder with different sound-effects.mp3 and a list of timestamps = (t1, t2, t3...). I would like to be able to insert any sound-effect at any given time in the video. Furthermore a sound may last multiple seconds and overlap another sound. I've tried to visualize the concept with images.

Preferably this would be done in Python. However, I would be extremely happy if anyone took their time to help me out using any means of programming required.

  


  I have tried using Moviepy without much success as I am only able to add sound to the start of the video. Perhaps ffmpeg is the way to go.
