Original author: Didée (https://forum.doom9.org/showthread.php?t=166082)
Small and relatively fast realtime-sharpening function, for 1080p,
or after scaling 720p → 1080p during playback.
(to make 720p look more like being 1080p)
It's a generic sharpener. Only for good quality sources!
(If the source is crap, FineSharp will happily sharpen the crap) :)
Noise/grain will be enhanced, too. The method is GENERIC.
Modus operandi: A basic nonlinear sharpening method is performed,
then the *blurred* sharp-difference gets subtracted again.
Args:
mode (int) - 1 to 3, weakest to strongest. When negative -1 to -3,
a broader kernel for equalisation is used.
sstr (float) - strength of sharpening.
cstr (float) - strength of equalisation (recommended 0.5 to 1.25)
xstr (float) - strength of XSharpen-style final sharpening, 0.0 to 1.0.
(but, better don't go beyond 0.25...)
lstr (float) - modifier for non-linear sharpening.
pstr (float) - exponent for non-linear sharpening.
ldmp (float) - "low damp", to not over-enhance very small differences.
(noise coming out of flat areas)
hdmp (float) - "high damp", this damping term has a larger effect than ldmp
when the sharp-difference is larger than 1, vice versa.
rep (int) - repair mode used in final sharpening, recommended modes are 1/12/13.

Denoise with MDegrainX, do slight sharpening where motionmatch
is good, do slight blurring where motionmatch is bad.
In areas where MAnalyse cannot find good matches,
the Blur() will be dominant.
In areas where good matches are found,
the Sharpen()'ed pixels will overweight the Blur()'ed pixels
when the pixel averaging is performed.
Args:
bblur, csharp (int, float or function) The method to smooth/sharpen the image.
If it's an int or a float, it specifies the amount in Blur() and Sharpen().
If it's a function, it will use the specified function to smooth/sharpen the image.
tr (int) - Strength of the denoising (1-24).
thSAD (int) - Soft threshold of block sum absolute differences.
Low value can result in staggered denoising,
High value can result in ghosting and artifacts.
rec (bool) - Recalculate the motion vectors to obtain more precision.
chroma (bool) - Whether to process chroma.

Author: Didée (https://avisynth.nl/images/SeeSaw.avs)
(Full Name: "Denoiser-and-Sharpener-are-riding-the-SeeSaw")
This function provides a (simple) implementation of the "crystality sharpen" principle.
In conjunction with a user-specified denoised clip, the aim is to enhance weak detail,
hopefully without oversharpening or creating jaggies on strong detail,
and produce a result that is temporally stable without detail shimmering,
while keeping everything within reasonable bitrate requirements.
This is done by intermixing source, denoised source and a modified sharpening process, in a seesaw-like manner.
You're very much encouraged to feed your own custom denoised clip into SeeSaw.
If the "denoised" clip parameter is omitted, a simple "spatial pressdown" filter is used.
Args:
NRlimit (int) - Absolute limit for pixel change by denoising.
NRlimit2 (int) - Limit for intermediate denoising.
sstr (float) - Sharpening strength (don't touch this too much).
Slimit (int) - Positive: absolute limit for pixel change by sharpening.
Negative: pixel's sharpening difference is reduced to pow(diff, 1/abs(Slimit)).
Spower (float) - Exponent for modified sharpener.
Szp (float) - Zero point, below: overdrive sharpening, above: reduced sharpening.
SdampLo (float) - Reduces overdrive sharpening for very small changes.
SdampHi (float) - Further reduces sharpening for big sharpening changes. Try 15~30. "0" disables.
bias (float) - Bias towards detail (> 50), or towards calm result (< 50).
Smode (int) - RemoveGrain mode used in the modified sharpening function (sharpen2).
Negative: absolute value specifies the MinBlur radius used.
NSmode (int) - 0 = corrected, 1 = original nonlinear sharpening.
sootheT (int) - 0 = minimum, 100 = maximum soothing of sharpener's temporal instability.
Negative: will chain 2 instances of temporal soothing.
sootheS (int) - 0 = minimum, 100 = maximum smoothing of sharpener's spatial effect.
ssx, ssy (int) - SeeSaw doesn't require supersampling urgently, if at all, small values ~1.25 seems to be enough.
diff (bool) - When True, limit the sharp-difference instead of the sharpened clip.
Relative limiting is more safe, less aliasing, but also less sharpening.
This parameter has no effect when Smode <= 0.
