I am using a combination of Cookie Cutter and Gaussian Blur to mask some product labels on bottles in a tutorial video I am creating with Movie Studio 13 Platinum( or Suite which is what the box says). These bottles move around in the shot so I am attempting to move the center of the circle and create keyframes. The problem is with the slider in the dropdown when I click on the clock symbol. It will not advance the video so I can stop, move center over new location, create keyframe and advance to next spot on timeline. I currently have to document where I am on the shot in the main screen and hopefully move the slider to the right spot in the secondary Event FX screen. Has anybody experienced this? is there a setting I am missing? I just updated my graphics card thinking that was the issue but it still does not seem to want to work. any help is greatly appreciated.
