Does upgrading from demo remove watermark?

I made my first stop motion animation! I used the free demo version, and it has that white text watermark thing in the corner that says “captured with a demo version…” If I upgrade to the home version, will that remove the watermark on a video I’ve already made? Or does it only remove it for future videos?

Here is the youtube link if you want to watch it! – http://youtu.be/EPWvMOGtUDg

I am deeply sorry, but the watermark is branded into the image in the capture process and can’t be removed automatically anymore. Your stopmotion video is really nice and I can see why you want the watermark to be removed.
