Difforum · Upscale (2K / 4K)
Finish at 2K (or 1080p / 1440p / 4K / xN) for delivery. With an upscale model (Load Upscale Model: 4x-UltraSharp, RealESRGAN, 4x_foolhardy_Remacri...) each frame is upscaled by the model in chunks, then resized to the exact target; without one it is a clean Lanczos resize. Aspect is kept and sizes stay even for video codecs. Bypass the node (or its group) to deliver at render size.
