title: Transforming Video Pixel Map
body: <p>one of the lectures I am taking right now has recorded all sessions but the whole video of some lectures is weirdly shifted. An example screenshot:</p>
  
  <p><a href="https://i.stack.imgur.com/5LD5u.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/5LD5u.jpg" alt="enter image description here"></a></p>
  
  <p>Does anyone know how transform a whole video (90 minutes) (not just a single image) to be in the right format? Maybe using ffmpeg?</p>
  
  <p>The efficiency is important here, I could surely write a script that does that for one image but this is about ~ 10 lectures each 90 minutes.</p>
  
  <p>It is not important that the color is shifted differently. The black and white content is the most important one.</p>
  
  <p>Best,
  Moritz</p>
