How to Crop Video on Mac in VLC?

I notice that some users tried to crop videos on Mac with VLC player, therefore, I installed it and tested to check if it crops a video.

VLC media player does have a Crop feature in its video toolbar, but you can only crop video in the playing, there is no option offered to save the cropped video. You can crop video on Mac temporarily in VLC as follows:

  1. Open the video in VLC player.
  2. Head to Video>Crop, choose an aspect ratio.crop video vlc 1

Also, I tried to follow the videos to crop video in VLC by tweaking video effects, preferences, video cropping filter. When I tried to export the video, I am not allowed to use the video-cropping filter, therefore, I cannot crop videos in VLC permanently.
