I am learning a bit a about tracking and so I am moving the attach point and search region etc to the area of my clip that I want to track and as I do so it magnifies the region as it should however after I resize the feature and search regions I am having diffculty getting the magnify to work again. Each time I place the cirsor over the points over the corner points appear and I can move it but the magnify doesnt turn on again. Not sure why?
A little more information about your system and your AE version would help. The normal behavior is to give you the expanded view when you click and move the tracking area. If you don't see the bold crossed double ended arrows when you click and drag you won't get the expanded view and you won't be moving your track point. If you selected the attach point (small crossed arrows) and move that you won't get the expanded view.
