Answers.Text: HAHA! I did disable the Contrast Enhancer in the **Intel UHD Graphics Control Panel** and now the video played by **MP-HC** is displaying correctly.
  Thanks. Now, why was the other player not affected by this option?

Title: Video created with FFmpeg has a strange contrast level while playing in some video players
UserDisplayName: Nicke Manarin
ThreadText: # Video created with FFmpeg has a strange contrast level while playing in some video players
  
  (Asked by: username_0 on 2019-10-26)
  
  I'm using these parameters to encode multiple PNGs into a MP4 file using `FFmpeg`:
  
  ```
  -vsync 2 -safe 0 -f concat -i ".\concat.txt" -c:v libx264 
  -pix_fmt yuv420p -vf "pad=width=2044:height=1152:x=0:y=0:color=black" -y ".\Test.mp4"
  
  ```
  
  But it's creating a video in which some players are not capable of displaying the correct contrast level. What's happening? I'm probably doing something wrong.
  
  Windows Media Player and MP-HC are not displaying with the correct contrast level, but the Movies and TV is able to.
