title: ffmpeg resizing video puts it at wrong resolution
body: <p>I have a 1080p video that i'm trying to resize for an iOS app upload. So i tried scaling it to the iPhone 6 resolution of 1334x750:</p>
  
  <pre><code>ffmpeg -i WrathTrailer.mp4 -strict -2 -vf scale=1334:750 WrathTrailer1334x750.mp4
  </code></pre>
  
  <p>The output file comes to 1333x750. iTunes connect won't accept it. Any ideas?</p>
