At roughly one minute and half rendering per frame, and twenty-four frames per second that makes about thirty-five minutes for ever second of animation. Which comes to 2160 minutes (or thirty-six hours) for every minute of animation. At a personal narrative target of three minutes, that makes for hundred-and-eight hours of rendering total.
90sec x 24 = 2160sec / 60 = 36min for 1sec || 36min x 60 = 2160min / 60 = 36hrs for 1min || 36hrs x 3 (minimally) = 108hrs / 24 = 4.5days for 3min.
I'm at a complete loss how I'm going to even marginally optimize this more than it already is. Ugh, this may actually kill me. I mean, this is after all adequate framerate at 720p in possibly the worst environment (indoor and in lowlight) but still.
I'm looking into hardware upgrades, but I'm intensely dimwitted when it comes to GPUs. I may need another mind on this.
