title: ffmpeg - adding text to a video between two times
body: <p>Hi I have a video which is 20 seconds long, I want to add some text to this video from 00:00:10 seconds to 00:00:15 seconds which just says "Summer Video" and fades in and out using FFMPEG.</p>
  
  <p>I know I have to use the drawtext filter, but has anybody got any examples?</p>
  
  <p>Thank you. </p>
