# TemporalCleaner

## Abstract

author: TemporalCleaner (by Jim Casaburi; ported to AviSynth by Vlad59)
version: Beta 2
dowload: http://www.avisynth.org/warpenterprises/
category: Temporal Smoothers
requirements:

- YUY2 Colorspace
- ISSE support

## Description

TemporalCleaner is an avisynth port of the original port of the VirtualDub filter made by Jim Casaburi.

I just added some ASM to Jim's algo.

### 1 - What it does

if the difference between previous pixel and current pixel is below a blur threshold then replace the current pixel by the average between previous and current pixel else keep current pixel.

An other trick is to add some feedback to this filter : instead of using the unfiltered previous frame it uses the already filtered one.

Simple isn't it ?

### 2 - Parameters

`TemporalCleaner` (clip, int "ythresh", int "cthresh")

ythresh (default value = 5) : blur luma threshold (don't go above 8 otherwise you'll have some ghosting).

cthresh (default value = 10) : blur chroma threshold (you can safely go a little above 8 as if luma is above threshold -> chroma is automatically kept (no blur)).

### 3 - Current limitations or known problems

- Work only with YUV2, CHECKED.
- require a Integer SSE capable CPU (no PII and K6-II), CHECKED.
- Require a mod-4 width (NOT CHECKED)

### 4 - Credits

Thanks to
- Jim Casaburi for the original idea (I'm just his translator ;))
- Zarxrax and Ligh for the beta testing
