title: FFMPEG Video loop from images files
body: <p>I am trying to make a video from a bundle of image files and then apply a an overlay on top of it.Another requirement is to make the video loop 3x. It is simply not working.</p>
  
  <p>The first three paths are pointing toward the same image bundle. (A folder containing images like the following DSC0001_0013.jpg,DSC0002_0013.jpg,etc)</p>
  
  <p>Observed symptoms:</p>
  
  <p>The script runs infinitely.I produces a video file of 0 KB.I have to abort script using CTRL+C</p>
  
  <p>This is my script.</p>
