ComfyUI adds Nvidia RTX video upscaling, frame generation and HDR nodes

ComfyUI now runs Nvidia RTX video effects as custom nodes that process footage locally on an RTX GPU, according to Comfy's blog post.

The RTX Video Super Resolution node upscales up to 4× across 19 modes, the Frame Generation node creates frames at 2× to 16×, and the RTX Video HDR node converts SDR to BT.2020 HDR at 400 to 2000 nits. The release also adds half-float and full-float EXR read and write support and a Convert Image Color Space node.

Comfy says the models are fast, lightweight, and ship with the nodes. An X post from ComfyUI says the super resolution node also handles denoising and deblurring, and that the three nodes can be chained before footage returns to a VFX pipeline.
