title: FFMPEG - Short video - Loop to make it bigger
body: <p>I create animated video.
  But the video is very short.</p>
  
  <p>So i am trying to increase the length of the video. It is animated, so it will not make any difference.</p>
  
  <p>I am doing it with cat function.
  Is there anyway to loop it without using the concat?</p>
  
  <p>I create mp4. To copy the videos i convert them to mpg. Again i convert them to mp4. It is a long process. So, If i can increase the timing by looping the video, I don't need to do other convert process. Is it possible in ffmpeg?</p>
