SeeSaw is a function that uses a balance of denoising and sharpening to enhance a clip
This filter averages pixels in a configurable radius around a source pixel that are within a configurable threshold of the central pixel. This has the effect of blending low-level video noise while retaining sharp details.

== Description ==
== 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.

Abstract

This filter averages pixels in a configurable radius around a source pixel that are within a configurable threshold of the central pixel. This has the effect of blending low-level video noise while retaining sharp details.

Description

NRlimit int = 2
Absolute limit for pixel change by denoising

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,

Examples

avisource("Blah.avi")
