Ever notice how much time you spend rendering identical images? Maybe your animated character pauses to think, or maybe you're just using (and reusing) a limited number of poses. But sometimes it seems that over half the frames you spend precious time rendering are identical the frames you've already rendered. Sure, you can try to keep track of which ones are duplicates and then wrangle those files by hand, but situations get complicated quickly, and it ends up being easier to just bite the extra render time and save yourself the headache.
Well dopplerender solves all that. It's not a new renderer. It's not an image processor. It's just a really simple Python script that uses a couple of clever tricks to figure out which frames in your animation are duplicates, and then renders them only once. Then it fills in all the other doppleganger frames by soft linking to the rendered file. Easy peasy. And really, really fast.
In my test cases, (real animation projects creating illustrations for my YouTube series) dopplerender cut my rendering time in half.
I've been using dopplerender in my own production process for a couple of weeks now, and I think it's time to start getting some feedback from other users.
