RE:Vision Effects has released DE:Noise 1.0, a plug-in that removes excessive noise and artefacts from video.
The software works with After Effects and Final Cut Pro/Motion. It handles frame-to-frame defects ranging from fine digital and electronic noise to blotchy spots.
The plug-in combines proprietary motion estimation (optical flow) techniques with 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, renders affected by ray-tracing sampling artifacts, fingerprints and dust captured during film scan/transfer and printing, snow, drop-outs and many other defects.
The software also offers pre-processing contrast controls to help enhance the noise for easier elimination.
A full versions of the software costs $149.95 (available at introductory $99.95 price until 30 September). Render-only licenses cost $29.99.
