title: ffmpeg overlay image with fade in and fade out
body: <p>So I had a PNG overlay a video, and this was working perfectly, now I want the same png that worked previously only show for a certain duration, and have it fade in and fade out.</p>
  
  <p>But my new command just has no image, where in the past it had the image.</p>
  
  <p>Can you please assist, maybe I am just attempting it incorrectly.</p>
