Abstract

A motion compensated noise removal script with an accompanying post-processing component.
This script is a motion compensated temporal denoiser, which utilizes both pixel and motion masks to obtain the highest quality output. It also includes a variety of post-processing filters, everything from sharpening to anti-aliasing to halo removal. Plus much more!

Required Filters

Latest versions of the following filters are recommended unless stated otherwise.
Note: You do not necessarily need all of these filters for this script to function. There are special modes that enable the use of specific filters at specific times, but these are only used when necessary. Just to be safe, make sure you have all of the filters listed below in you 'Plugins' folder.

• FFT3DFilter or FFT3DGPU
• RemoveGrain and Repair - part of the RemoveGrain v1.0b package.
• RgTools - recommended drop-in replacement for RemoveGrain & Repair!

This is the post processing portion of MCTemporalDenoise, and it has the wonderful ability to be called externally.It differs from MCTemporalDenoise in the fact that it doesn't denoise, and that all settings default to off. Meaning, you do nothing without turning on a feature.

Parameters are the same as MCTemporalDenoise.

'Sharp' & 'Protect' options need 2 inputs/ Example:

The others only need 'denoised'.

By default, all filters are off!

Examples
