The next time I sit down to do a movie, I want to really start making a movie. What I mean is where every aspect of what goes into a final film counts from the very beginning, particularly motion and audio.
This doesn't mean start animating without a script or boards, just that the script and boards may include some animation, sound and music. I could imagine, for example, how I want a film to open, perhaps with a camera pan on my first location. Rather than draw a long image on paper, start drawing right into Aura, even if just on a scribble level. Actually do the pan across the scribble in 2D. How long does it take? How big does the background image need to be. I could start building scenes, from quick sketches, 3D box animation, video, photos, lines recorded on a cheap mic, anything "quick and temp".
If this is done, making the film becomes a process of refining something that is established early on. Replace that scribble of a sketch with a final background. The same Aura project and the same 2D camera move would still apply, just the content changes. Replace those 3D boxes with the final car models. The animation was already done. Refine... refine...
