Basic compositingĬompositing is both a science and an art, but the user mechanics of Natron don't take long to pick up. Running Natron at the close of the installer may or may not work depending on how you installed it either way, after the install, launch it from either your file manager or applications menu. The install wizard will offer to install several third party tools, including the Tuttle effects install everything.
Run it either as a normal user to install it into your home directory (you might install it to ~/bin/natron, for instance), or with the kdesu or gksudo commands to install it systemwide (for example, you might put it in /opt/natron so that any user can access it).

On the big screen, you'll see this in nearly every movie since 1933's King Kong (or thereabouts), but the art has reached a science in the digital realm, where some movies are practically not so much as edited as they are superimposed.
A "comp artist," as they are called in the industry, specializes in taking disparate moving images and placing them in the same frame, usually to make it appear that the different elements were shot at the same time. If you've ever taken a digital photograph into GIMP to remove red eye or an ex-girlfriend or ex-boyfriend, or crop out a finger that got into the edge of the frame, then you are practically a compositor.
