Description
Non-linear Unsharp Masking, uses a wide-range Gaussian instead of a small-range kernel. Like most sharpeners, this script only processes luma, chroma channels are simply copied from the input clip.
Requirements
- AviSynth 2.5.8 or greater
- Progressive input only
- Supported color formats: YV12
Required Plugins
Additional planar colorspaces are supported when using AviSynth 2.6 and appropriate MaskTools2.
- NonlinUSM (clip o, float "z", float "pow", float "str", float "rad", float "ldmp")
- clip o =
- Input clip
- clip o =
- float z = 6.0
- zero point
- float z = 6.0
- float pow = 1.6
- power
- float pow = 1.6
- float str = 1.0
- strength
- float str = 1.0
- float rad = 9.0
- radius for "gauss"
- float rad = 9.0
- float ldmp = 0.001
- damping for very small differences
- float ldmp = 0.001
Examples
NonlinUSM with default settings:
AviSource("Blah.avi") NonlinUSM(z=6.0, pow=1.6, str=1.0, rad=9.0, ldmp=0.001)
