Outside work I build tools for problems I hit myself. Upflow2x exists because every interpolator I tried smeared the held frames in my anime edits. On EternalMonitor, the iPad second-screen app, I own AMD GPU support, from the AMF encoder to the software fallback.

Upflow2x

upflow2x.com

DaVinci Resolve Studio plugin that smooths and upscales video. It finds the held frames, draws the missing in-betweens with RIFE and upscales every frame 2x, all on your own machine.

EternalMonitor

I build it with the Sideband team and own its AMD GPU support. It turns an iPad into a second screen for Windows, extending or mirroring the desktop over Wi-Fi or USB with touch, keyboard and Apple Pencil input, and plays the PC's audio on the iPad.

Where the editing happens.

I create edits from anime, shows and movies for an audience of 12.8K, and Upflow2x came out of doing it. The footage is drawn on 2s, every interpolator I tried smeared the held frames, so I wrote one that treats the duplicates as deliberate. The edits themselves are built in After Effects, with nulls driving parented transforms, compositing in 3D space with camera moves, effects stacked deep, easing hand-tuned on every move, and the sound designed to match the cut.
