RE:Vision Effects DE:Noise for After Effects Compatible
DE:Noise handles spurious frame-to-frame defects ranging from fine digital/electronic noise to blotchy spots (e.g. dirt on the film). DE:Noise combines motion estimation techniques with feature-sensitive, edge-preserving spatial filtering methods to reduce the visual impact of various problems such as: noisy video (that can happen with low-light capture), excessive film grain, CG renders affected by ray-tracing sampling artifacts, fingerprints and dust captured during film scan/transfer and printing, snow, drop-outs and many other defects.
