title: ffmpeg create blank screen with text video
body: <p>I would like to create a video consisting of some text. The video will only be 0.5 seconds long. The background should just be some colour, I am able to create such video from a photo, but cant find anywhere how this could be done without a photo, just using text to create such video.</p>
  
  <p>Can you help me ? Thanks in advance</p>
