title: How to Bulk Add Outro with ffmpeg?
body: <p>I've got an script which is to bulk join and intro file, video files and a outro into one file:</p>
  
  <pre><code>cd converted
      for %%f in (*.mp4) do (
        echo.&gt;%%f.list
        echo file 'intro_outro/c_intro.mp4' &gt;&gt; %%f.list
        echo file '%%f' &gt;&gt; %%f.list
        echo file 'intro_outro/c_outro.mp4' &gt;&gt; %%f.list
      )
  
  
  for %%f in (*.list) do (
    ffmpeg -f concat -i %%f -c copy concatenated/%%f.mp4
  )
  </code></pre>
  
  <p>Now I have a problem, I just got a video file and an outro file and I don't need an intro.
  What do I need to change to just add an outro to the videos in bulk?</p>
