As descried in Lesson 2, you can use the built-in crop tool to select any desired portion of an image. Drag any of the 8 cropping handles to resize the selected portion (). The blue-tinted portion () will be removed. At the right are other advanced controls, described below.
Control the Aspect Ratio
By default, you can freely drag the cropping handles to select arbitrary size of image. It is recommended that the source images should have the same aspect ratio to avoid image distortion. The simplest method is to choose the same aspect ration from the Aspect Ratio Box () by cropping each source image. Note, if you have previously set the movie size, "Match to movie" is the best choice. The Landscape and the Portrait options will cause the aspect ratio to be reversed when cropping takes place.
Rotating is useful for aligning some digital camera images. Flipping may create a desired effect, and may also be used to bring images into closer alignment. Use the Rotate and Flip Switches () to perform these actions.
Here are three options in the Options () frame.

You can see info about the original image size and current cropped size in the Size Frame ().
