Title: inconsistent "Always Fit Window" behavior in VLC for two different videos
UserDisplayName: thanks_in_advance
ThreadText: # inconsistent "Always Fit Window" behavior in VLC for two different videos
  
  (Asked by: username_0 on 2024-11-24)
  
  Two different videos:
  
  * both have same resolution (1920 x 1080)
  * one processed with `Tencoder` (frontend for FFMPEG), and the other processed with `kdenlive` (video editor that uses MLT framework)
  
  **The issue:** they show up very differently in VLC.
  
  * One needs "Menu > Video > Always Fit Window" to be **checked** to fill the screen.
  * The other needs "Menu > Video > Always Fit Window" to be **unchecked** to fill the screen.

  * Resolution - 1080x1920
  * Pixel aspect - ratio 1:1
  * Display aspect - ratio 9:16
