Usage

core.spanns.SPANNS(VideoNode clip[, VideoNode ref, float sigma=1.0, float tol=0.0, float cutoff=0.9])

Parameter Description

• clip (VideoNode): The original video node. Only 32bit float input is supported.
• ref (VideoNode): Reference clip, a blurred one obtained from the original. It serves as an alternative way to control denoising strength. If provided, sigma will be ignored. Default is a 3-pass box blur with radius equal to sigma.
• sigma (float): Denoising strength. Default is 1.
• tol (float): Noise tolerance in the range [0, 1]. Default is 0.0.
• cutoff (float): Information components cutoff point in the range $[0.5, 1) \cup [1, \infty)$. Values that fall in the first interval represent a percentile cutoff, whereas the second interval represents the absolute top index. Higher values preserve less texture. Default is 0.9.
