title: FFMPEG Slow Video and Audio by Half
body: <p>I am using the latest version of FFMPEG and am trying to slow video and audio by half</p>
  <p>This is the best I could come up with</p>
  <pre><code>./ffmpeg.exe -i &quot;C:/ffmpeg/input.mp4&quot; -filter_complex &quot;[0:v]setpts=1.5*PTS[v];[0:a]atempo=0.5[a]&quot; -map &quot;[v]&quot; -map &quot;[a]&quot; &quot;C://ffmpeg/output.mp4&quot;
  </code></pre>
  <p>But the audio and video are not being slowed down at the same rate.</p>
  <p>Any suggestions?</p>
  <p>Thanks.</p>
