Comfy said on 13 October 2026 that Nvidia RTX video effects now run inside ComfyUI as custom nodes. Its [announcement](https://blog.comfy.org/p/nvidia-vfx-nodes-for-video-upscaling) describes a local finishing chain for existing footage: Super Resolution, Frame Generation, then Video HDR.

Super Resolution offers up to 4× scaling or target dimensions up to 8192 pixels, plus same-resolution denoise and deblur modes. Frame Generation interpolates at 2× to 16× or at a chosen timestep. The HDR node converts SDR to BT.2020 HLG or PQ.

The [node repository](https://github.com/Comfy-Org/ComfyUI%5FNvidia%5FVFX%5FNodes) requires an Nvidia RTX GPU and CUDA-enabled PyTorch cu130 or higher; frame generation needs an RTX 40-series GPU or later. CPU-only execution and non-Nvidia GPUs are unsupported.

The README says interpolated footage needs an adjusted encoding frame rate to retain its duration. ComfyUI IMAGE data carries no HDR colour-space metadata, so downstream tools must mark or encode the selected transfer function. The repository is Apache-2.0 licensed; that does not establish the terms for every bundled component. Motion Engineering Today has not tested the nodes.
