What is cropping?
Cropping refers to the removal of the outer parts of an image. So it remove something from left, right, top and/or bottom of image. Usually with videos cropping is used to change aspect ratio by cutting something out (known as Pan and scan method).
How to do it QT4
From QT4 GUI you can enable cropping from Tools -> Preferences... (Show settings: All) then Video and Video cropping field.
How to do it from command-line/terminal/shell
If you want to crop local video with command-line/terminal parameters, use
vlc input --vout-filter=crop --crop-geometry=120x120+10+10
120x120 is the wanted resolution (in pixels), and 10+10 is the top-left position where the cropping should start (in pixels)
or if you want certain aspect ratio
vlc input --vout-filter=crop --crop-ratio=1777
where 1777 is aspect ratio you want (divide it with 1000 to get correct value, in this case 1,777 aka 16:9)
