Well, what exactly are you doing? The message indicates that you are scaling your footage in some way or dropping a smaller clip in a larger composition and the stabilizer can't make sense of it... screenshots and more info might help to get to the bottom of this...
Thanks Mylenium, I just figured it out last night. I had to use the original footage from the camera. I was using footage exported from premiere pro. I think that must have been my problem. Thanks again.
same thing happens to me: both my clip and composition are in 1920 x 1080, don't know whats wrong.
