ThreadText: # App to rotate .mp4 video for Windows or Android
  
  (Asked by: username_0 on 2016-04-27)
  
  I have an .mp4 format video filmed in portrait format, when currently played on any `landscape` format device the people appear sideways.
  
  I would like a sipmle app for either Windows™ or Android OS to only rotate the video so it plays 'portrait format' on any 'landscape format' device, such as a Smart TV.
  
  Any suggestions ?

  If I've understood you correctly, your video appears upright when viewed in portrait orientation and rotated in landscape. This suggests the image is stored in a landscape matrix but with no rotation tag set. If so, there are two things you can try using [ffmpeg](https://ffmpeg.org/download.html), a free command line tool.
  
  ```
  ffmpeg -i input.mp4 -c copy -metadata:s:v rotate=90 output.mp4
  
  ```
  
  If your landscape devices don't understand or obey the rotation tag,
  
  ```
  ffmpeg -i input.mp4 -c copy -vf transpose=2 -c:v libx264 -crf 20 output.mp4
  
  ```
  
  The 2nd command will re-encode the video portion of your file. CRF controls the quality - lower is better but will produce bigger files.
  
  In the commands, you may have to switch the `90` with `-90` and `2` with `1` depending on how the video was stored.
