Final renders are included with all CGI deliverables.  Rendering services can vary greatly in capacity from expensive farms having hundreds or even thousands of available CPUs, down to the more modest “garden-size” variety.  Rendering refers to the frequently notorious and often time-consuming process during which all elements viewed through a scene’s virtual camera are painted or “rendered” and then written out as a sequence of image files called frames.  Render “farms” are collectives of networked computers that compute different frames from the same image sequence simultaneously.  Using this distributed approach can reduce total render times exponentially; completing both lengthy or demanding image sequences in minutes or hours as opposed to days or weeks.  Regardless of capacity, the faster the rendering process, the more creative time can then be applied towards improvements and additions to any final results.
