Subject: After Effects (AE) -- Render only rendering info (CS6 and CC and
   Date: Tue, 26 Aug 2014 20:31:04 -0400

    Thanks to Brian Krusic for this info on AE render only rendering:

    I haven't tried this myself, but FYI:
    http://blogs.adobe.com/aftereffects/2012/06/codecs-and-the-render-engine-in-after-effects-cs6.html

    The gist of it being creating a file called "ae_render_only_node.txt"
    in /Users/Shared/Adobe/ to enable "non-royalty-bearing" render only mode,
    so if you're not using codecs that involve royalties, you can use this mode:

    "After Effects CS6 and After Effects CC include a significant change
    from After Effects CS5.5 regarding the ability to use network rendering
    without activation of render-only instances of the application, known as
    render engines.

    "After Effects CS5.5 had to be activated (serial number entered) on
    render-only machines due to licensing restrictions for certain codecs.
    See this post by After Effects product manager Steve Forde [links below]
    for more background about this."

    The link on that page is stale, due to the regular growth of Steve's blog,
    but these are I think the articles the above meant to point to:
