I've been mostly doing the editing and general After Effects work, hoping to add CGI elements later on.  The main challenge with the CGI seems to be lining it up with the footage (as, rather than using a not-so-free plugin or something else to put actual 3D into After Effects, I'm rendering the footage in Blender and then compositing it on top of the AE work).  One neat trick around this is that Blender does allow background images (including videos), so that'll be an excellent tool for matching up the camera and the video.  Hoping to get a lot of work done on it soon!
