I'm sorry but you are using terms I don't understand. "The Crop section of the Video TAB IN THE INSPECTOR! If you mean the Timeline viewer on the top right side of the workflow right above the Timeline itself then ok, I follow. But the Vido Tab in the Inspector, I have no clue what that is.
But the problem there is I don't see any "crop" tool to change values, I can adjust the size of the image by making it smaller or large, which is really the scale of the image and not a real crop of it. But I cannot find any crop tool to change the portion of image I would like to see, in this case for example I would like to see only the left half of the top image and the right half of the bottom image. This is what I cannot figure out.
I can move the two images that are in the Timeline from left to right in the viewer and see only half of them but they are the right halves or the left halves then yes I can see only half of the images at the same time but what I want is to be able to see the left half of the top image and the right half of the bottom image.
