This iMovie plug-in allows you to place many individual picture (of almost any format: jpg, gif, pict, ...) into your clip - at any size and then animate it (move and re-size it over the clip's duration). You can distort the picture, or force the plug-in to keep the picture's proportions.
You can set each picture's transparency and have an individual frame for each picture.
special conrols also allow you to define the time when each picture appears, and when it disappears.
This plug does not allow you to place movie clips into your clip. We have much better plugs for that. that's why this plug has the 'static' in it's name. It can only handle static (non-moving) pictures.
