Final Words about Crop Video on Mac with VLC

I notice that some users tried to crop videos on Mac with VLC player, however, I failed after several testing.

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.

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.vlc crop 05
