You know that effect where you see a photo of a person, and then a second photo is used, but it looks like the person actually crossed the room. So somehow an effect has interpolated blurred images bewteen the two stills, thereby faking a moving image (a clearer beginning, blurry middle, and clearer last image). How is this done? I tried simply applying a timeward between two images and slowing it down to 10% but it doesn't really do anything.
