Hello, I would like to adjust image qualities for my first iMovie project, however, I'm not able to get the Video Adjustments button to open the Video Adjustments window. In my video project , I select the video clip then click the Video Adjustments button only to get an eye dropper in the viewer. When I move the cursor (eye dropper) over the selected clip the cursor becomes a triangular arrow with a color wheel below it. The video adjustments icon at the upper righthand corner of the selected clip indicates adjustments have been made but when I click the icon to view nothing happens. Assistance is sought and appreciated.
