We suggest that you pick a typical shot from your project and tweak the filter in detail to get the best results for this shot. This is automatically handled in FCP-in other hosts we recommend that you set your project to render in 16 bit or float. The filter gives better results when the host is set to render in 16 bit or float, even if the source media is 8 bit. The default settings for the filter assume there will be slightly more noise in Cb than in Cr. The signal to noise ratio is generally highest in the Y channel, and often higher in Cr than it is in Cb, The filter allows most of its settings to be made independently in the three channels-generally you will want to do a lot less smoothing in Y than in Cr and Cb, and may (depending on your camera) want to do more smoothing in Cb than you will in Cr. The filter works in YCrCb color space, which is the color space in which video signals are delivered.
This filter is designed to remove noise from camera images, and will not work properly unless the input is fully opaque. This allows us to smooth out the noise without losing detail.
For each pixel, it blends in pixels that are close (in color) to the pixel, while ignoring pixels that are distant in color. The BCC Noise Reduction filter smooths out noise by comparing each pixel with the pixels in it’s immediate temporal and spatial neighborhood.
