The easiest way to customize a template-based project is to exchange the media used
in the template with your own media, from the File Browser or the Library. When you
exchange media, the new media item appears in your project with the same parameter
values used by the previous object. In addition, filters, masks, behaviors, or keyframed
parameters applied to the original media remain applied to the exchanged media.
