For your landscape images, select one and then open the pan/crop window. With cursor somewhere on the image, right-click and select Match Output Aspect. Then close the pan/crop window. Next, simply copy that event. Then select the remaining landscape images, right-click again, and select Paste Event Attributes. Each of the selected images should now fill the entire screen. It’s best to first fill your frame, before applying any motion effects such as panning or zooming with keyframes. You will have to do your portrait images separately. Easiest way again, if you want them all the same, is to pan/crop the first, copy, then select the remaining images, and again Paste Event Attributes. For a portrait image, the best way to initially pan/crop is to first apply the 16_9 preset, not default, and then zoom out until the frame covers whatever part of the image you desire. This way, you can move it anywhere in the frame you want. Hope this helps. Good luck.
