OK. I'm missing something.
I opened the video in VLC. Played to a certain scene and paused video.
I went to tools>adjustments/effects>video effects>crop.
I sent the top, bottom, left, right numbers to crop video just as I wanted and pressed the bottom/right close button in that window.
Under ESSENTIALS. I checked that IMAGE ADJUST box and adjusted the brightness and gamma.
I then went to top/left and clicked on MEDIA>Convert/save, which opened a MEDIA SAVE window.
I selected the file I had adjusted and paused.
I then pressed the bottom/right CONVERT/SAVE button.
I go down to the profile line and click on the little wrench/screwdriver button that says "edit selected profile".
Under VIDEO CODEC, I go to FILTERS, scroll down to video cropping filter and check that box and press save.
I type in a destination file name on my desktop for the new video and press START.
The result is a new video that has not been cropped. It looks exactly like the original file
What am I doing wrong? THANKS
