YARUI - Boost Your Render Time is an addon for Blender from nocomstudios that applies deep learning technology to your renders. It upscales frames and performs frame interpolation for smooth frame transitions, all handled within the Blender workflow. The addon runs on the NCNN inference engine.
YARUI works with Blender-Internal, Cycles and Eevee render engines, so it fits alongside the render setup you already use in Blender 4.2 through 4.5. It reached Version 3, and the developer provides supporting materials including full PDF documentation and a video manual guide covering introduction, usage, benchmarks and test results.
Distributed under the MIT license, YARUI is documented in detail through its PDF, which covers installation, usage, system requirements, an FAQ and changelogs. A demo video is also available for those who want to see more before installing. It sits within the superhive library as a rendering and workflow tool focused on saving render time.
