It’s not too often I get to write about a new old-school tool for making lo-fi graphics. Both because I haven’t written a news article in ages (sorry!), but also since everything today is either a mobile app, a cloud service, or powered by generative AI. Who am I kidding, it’s all 3 at once!

Lester, developed by Ruben Tous, an associate professor in the Department of Computer Architecture at the Polytechnic University of Catalonia, is a classic, offline program that fills you with nostalgia just as much as the beloved animation technique it’s built for. And I’m not just saying that because it has the ZX Spectrum palette built in!

The algorithms packed in the tool speed up production significantly as all you have to do is click on the areas of the input video you want to create clusters for and it can propagate them to all future frames. The magic is all open-sourced and described in Ruben’s research article Rotoscope Animation through Video Object Segmentation and Tracking.

It takes a bunch of time to process the frames and the results aren’t (always) perfect, but I’d rather get some extra work done while it’s silently purring in the background and then clean up the base animation than manually color over each individual frame myself.

Good luck getting these 167 frames done by hand (although I do miss all the TV shows I managed to watch when doing repetitive tasks like that).

If you’d like to add Lester to your own toolchain and stand next to classics such as Prince of Persia and Another World, get it here (free, macOS/Windows).
