Abstract
SeeSaw is a function that uses a balance of denoising and sharpening to enhance a clip
Requires Filters
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.
NRlimit int = 2
Absolute limit for pixel change by denoising
NRLimit2 int = NRlimit+1
Limit for intermediate denoising
Sstr float = 1.5
Sharpening strength (don't touch this too much).
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))
Spower float = 4
Exponent for modified sharpener.
Szp float = 16+2
Zero point - below: overdrive sharpening - above: reduced sharpening.
SdampLo float = Spower+1
Reduces overdrive sharpening for very small changes.
SdampHi float = 24
Further reduces sharpening for big sharpening changes. Try 15~30. "0" disables.
bias float = 49
Bias towards detail ( >= 50 ), or towards calm result ( < 50 ).
Smode int = ssx<1.35 ? 11 : ssx<1.51 ? 20 : 19
Uh?
sootheT int = 49
0=minimum, 100=maximum soothing of sharpener's temporal instability.
(-100 .. -1 : will chain 2 instances of temporal soothing.)
sootheS int = 0
0=minimum, 100=maximum smoothing of sharpener's spatial effect.
ss_x float = 1.5
ss_y float = 1.5
SeeSaw doesn't require supersampling urgently,
if at all, small values ~1.25 seem to be enough.
