Values input here are the number of pixels from that edge the crop extends, as you are setting it, this is displayed with a green block signifying the area of the image that will be removed. There are two options for cropping, you can use the Auto crop feature, which will detect any black lines and crop the footage between them, or if you are using the crop tool for something else, or just want to do it manually, you can set the crop via the left right top and bottom boxes. Selecting ‘Crop’ from the menu and pressing the green plus symbol at the bottom activated the crop tool and presents you with yet another view that allows you to adjust the crop to your tastes.
