I've got Premiere Elements 4.0 and I'm wanting to use the active camera effect, but when i apply it to a clip nothing happens. It doesn't change the clip in the preview. I can adjust all the properties like rate and stuff, but it doesn't do anything. I thought It might be a problem with the preview so i saved a sample and nothing. It doesn't move at all like i want it to. I check the other motion effects and none of them seem to have any effect on my clip. All other effects work fine. Anyone have any suggestion?
