Noise reduction (NR)

Noise reduction (NR) is the process of removing the random grain and colour speckle that a camera sensor adds, especially in underexposed or low-light footage. Resolve offers it in two forms. Temporal NR compares several frames forwards and backwards in time, separates the parts that move from the parts that don’t, and cleans the still areas without softening real detail — it is the gentler, detail-preserving option when motion estimation is good. Spatial NR works inside a single frame, blurring away noise but risking smeared texture if pushed too far. Used together, lightly, and verified on the RGB parade, vectorscope and at 1:1 zoom, they clean an image without turning skin plasticky. Denoise before you key or grade, so every downstream node sees a clean signal.
