title: Having problems running my unix ffmpeg script on windows
body: <p>im trying to run this script for converting between the two formats of VR on a windows machine</p>
  <pre><code>ffmpeg -i input.mp4 \
  -filter_complex &quot;[0:v]crop=in_w/2:in_h:0:0 [top];
  [0:v]crop=in_w/2:in_h:in_w/2:0[bottom];
  [top][bottom]vstack,
  scale=iw*min(2000/iw\,2000/ih):ih*min(2000/iw\,2000/ih),
  pad=2000:2000:(ow-iw)/2:(oh-ih)/2[outv]&quot;
  -map &quot;[outv]&quot; -map 0:a -c:a copy output_3dv.mp4
  </code></pre>
  <p>from what ive found i think the \ characters need to be swapped with ^ like this</p>
  <pre><code>ffmpeg ^
  -i input.mp4 ^
  -filter_complex &quot;[0:v]crop=in_w/2:in_h:0:0 [top]; [0:v]crop=in_w/2:in_h:in_w/2:0[bottom]; [top][bottom]vstack, scale=iw*min(2000/iw,2000/ih):ih*min(2000/iw,2000/ih), pad=2000:2000:(ow-iw)/2:(oh-ih)/2[outv]&quot; ^
  -map &quot;[outv]&quot; -map 0:a -c:a copy output_3dv.mp4
  
  </code></pre>
