Motion Adaptive 3D Noise Reduction

The following clips demonstrate the ability of our advanced video noise reduction technology to salvage troublesome, noisy footage into a useable result. This is an extreme example; even with good source footage, noise reduction can have a very significant impact on the quality of the compressed result. Digital Rapids encoders feature motion adaptive 3D noise reduction, delivering the benefits of noise reduction — not only the removal of visible noise, but also allowing the codecs to work more efficiently and thus create a higher quality output — without the trail artifacts that may occur with other 3D noise reduction methods.

Without noise reduction — This clip represents the raw footage as captured by a 3 chip DV camera in very challenging lighting conditions. Obviously there are quite a number of things wrong with the footage in question. The video is too bright, there is a lot of video noise from the camera's auto gain (trying to compensate for low light) and there is very little contrast in the image. Look in the background of the clip and you will see that the graininess induced by the camera.

With 3D motion adaptive noise reduction — 3D motion adaptive noise reduction has been applied to the clip and there is already a significant improvement in quality over the original footage.

With 3D motion adaptive noise reduction and some simple processing applied — Some simple proc amp adjustments have been applied to the clip to try and restore some contrast and saturation to the image. The footage is not perfect, but it is no longer wasted footage and can now probably be used for its original purpose.
