== Abstract ==
SeeSaw is a function that uses a balance of denoising and sharpening to enhance a clip

=== Requires Filters ===
*[[RemoveGrain]] 1.x
*[[MaskTools2]]

== Description ==
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.

{{Par|NRlimit|int|2}}
Absolute limit for pixel change by denoising

{{Par|NRLimit2|int|NRlimit+1}}
Limit for intermediate denoising

{{Par|Sstr|float|1.5}}
Sharpening strength (don't touch this too much).

{{Par|Slimit|int|NRlimit+2}}
positive: absolute limit for pixel change by sharpening
negative: pixel's sharpening difference is reduced to diff=pow(diff,1/abs(limit))

{{Par|Spower|float|4}}
Exponent for modified sharpener.

{{Par|Szp|float|16+2}}
Zero point - below: overdrive sharpening - above: reduced sharpening.

{{Par|SdampLo|float|Spower+1}}
Reduces overdrive sharpening for very small changes.

{{Par|SdampHi|float|24}}
Further reduces sharpening for big sharpening changes. Try 15~30. "0" disables.

{{Par|bias|float|49}}
Bias towards detail ( >= 50 ), or towards calm result ( < 50 ).

{{Par|Smode|int|ssx<1.35 ? 11 : ssx<1.51 ? 20 : 19}}
Uh?

{{Par|sootheT|int|49}}
0=minimum, 100=maximum soothing of sharpener's temporal instability.
(-100 .. -1 : will chain 2 instances of temporal soothing.)

{{Par|sootheS|int|0}}
0=minimum, 100=maximum smoothing of sharpener's spatial effect.

{{Par|ss_x|float|1.5}}
{{Par|ss_y|float|1.5}}
SeeSaw doesn't require supersampling urgently,
if at all, small values ~1.25 seem to be enough.

== Examples ==

avisource("Blah.avi")
SeeSaw()

a = TheNoisySource
b = a.YourPreferredDenoising()
