Adam Pizurny

Gen AI Innovation Specialist × ComfyUI Custom Node Developer

Building the bridge between traditional VFX production and AI-enhanced workflows — building tools, not just using them.

What I Build

Custom ComfyUI nodes and AI pipeline tools for production VFX:

Comfyui-FeedbackSampler

Experimental custom sampler for Deforum-style zoom animations through iterative feedback loops.

ComfyUI-AV-Handles

Add and remove stabilization frames with synchronized audio for video diffusion models.

ComfyUI Latent Transform Sampler

Advanced latent space transformations during diffusion sampling.

Open Source Contributions

Production Experience

Gen AI Innovation Specialist @ DNEG Brahma (Jan 2026 - Present) Identifying and prototyping cutting-edge GenAI technologies for tier-1 VFX production. Building ComfyUI pipelines, training custom models, and serving as the bridge between research and production.

AI Technical Artist / Generative AI Engineer @ UPP a.s. (Jan 2024 - Dec 2025) Led AI initiatives for commercial production, delivering AI-enhanced VFX from concept to final delivery.
