Opus 5.5 turns paper PDFs into 3Blue1Brown-style animations

A researcher skipped his storyboard-and-render workflow and gave paper PDFs directly to Opus 5.5, which produced coherent 3Blue1Brown-style explainer animations in about an hour.

Opus 5.5 is so powerful it made my previous workflow for making teaser videos for papers seem over-optimized, which consisted of an iterative loop of storyboarding and rendering. I simply threw my paper PDFs at it, asked it to generate @3blue1brown-style animations, and let it crunch for an hour. Not only did it generate perfectly coherent animations that adhered to the 3b1b style, it also came up with a lot of nice visualizations and toy experiments that illustrated core concept completely unprompted! Zero hand-holding. To celebrate entering the last year of my Ph.D., here are the one-shotted animations for some of my selected past projects, starting with Foveated Diffusion (https://bchao1.github.io/foveated-diffusion/). The moving gaze visualization at 0:16 and the pipeline and 0:24 is so cool!
