title: Generate MP4 video file by sequence PNG images in Java 8
body: <p>After testing several tools for Windows 10 found on the network, I had great difficulty in finding one that could carry around 5,000 PNG images in sequence and convert it into a video that was transmitted at the speed I wanted. I wasted a lot of time on something that is apparently simple.</p>
  
  <p>The known ffmpeg would be a good alternative, but it did not work on my Windows 10 (permission denied). I tested a lot of free software, but most of it crashed or closed abruptly.</p>
  
  <p>Until others can suggest a good solution here, preferably free, I will post my answer below, with a solution built on Java 8 itself.</p>
