✺ Showcase
Pulled straight out of an AE timeline. Drag the handle to compare — left is source, right is what St6 sends back.
✺ What it does
RIFE 4.25-heavy on TensorRT runs at ~200 fps. Slow-motion, ensemble pass, scene-cut detection — pick any factor from 1.5× to 40×.
Real-CUGAN-Pro, Real-ESRGAN, Waifu2x, ShuffleCugan, SPAN — all on a single dropdown. Anime → CUGAN, live action → ESRGAN. Or hit auto-detect and let the panel pick.
Depth-Anything-V2 with 22 OpenCV colormaps + RGB-guided edge sharpening. Native resolution — drop straight into AE for 2.5D parallax + shader displacement work.
Drag-reorder, pin-to-top, cancel-all. Color-coded status with live phase + percent + ETA. Survives AE crashes via auto-orphan cleanup.
Autumn, Midnight, Sakura, Forest. Custom-accent picker, reduced-motion mode, color-blind palette. Filename templates + a tidy [st6.outputs] folder.
JRPG sound bank when renders finish — Coin, Level Up, Quest, Item Get. Discord rich presence with the burnt-amber leaf + live phase + percent.

🪶 Companion
A second panel built for the rigs that can't run TensorRT — 4 GB VRAM, 8 GB RAM, integrated graphics. Same autumn UI, same upscale + interpolate workflow, ten times smaller install.
No Python, no CUDA, no PyTorch — just signed Win64 binaries and a setup wizard. Works on every GPU made since 2015 (NVIDIA, AMD, Intel, including iGPUs).
Built from scratch — a custom C++ ncnn runner + a single-graph mega-Net conversion of RIFE 4.25 heavy. No public NCNN port existed for 4.25 before this. Works at any resolution.
Auto-detects your GPU vendor and routes RIFE 4.25 through TensorRT on NVIDIA, DirectML on AMD, OpenVINO on Intel — when the main panel is also installed alongside Lite.
Real-CUGAN-Pro upscale, four utility buttons (Regroup, Dead Frame Remover, Precompose, Twixtor), autumn theme, UI scaling. Installs as a separate extension — runs side-by-side with the main panel without conflict.
