title: Video encoding with AV1 - FFmpeg
body: <p>I was trying to encode a raw video with AV1. </p>
  
  <p>I used: <code>ffmpeg -i netflixboxing720p.y4m -c:v libaom-av1 -b:v 500k -strict experimental netflix720p500AV1.mp4</code> </p>
  
  <p>I took 2 hours and when I open the created video I get nothing. I would play the Video.
  Do I need an other command line?</p>
