Description

High Quality DeNoise 3D is an AviSynth 2.5 port of the MPlayer filter of the same name. It performs a 3-way low-pass filter, which can completely remove high-frequency noise while minimizing blending artifacts.

Requirements

• AviSynth 2.5.8 or later
• Progressive input only
• Supported color formats: YV12

Syntax and Parameters

hqdn3d(clip, float "ls", float "cs", float "lt", float "ct", int "restart")

clip  clp =

Input clip.

float  ls = 4.0

float  cs = 3.0

Luma and chroma spatial filter strength.

float  lt = 6.0

float  ct = 4.5

Luma and chroma temporal filter strength.

int  restart = lt+1

Whenever a frame is requested out of order, restart filtering this many frames before. While seeking still slightly affects the content of the frames returned, this should reduce the disturbance to an unnoticeable level.

• Filter strengths vary from 0 (no filtering) to 255 (there will be nothing left of your video). If any options are omitted, they will assume a value based on any other options that you did specify.
  For example, hqdn3d(ls=2) is equivalent to hqdn3d(ls=2, cs=1.5, lt=3, ct=2.25).

Examples

hqdn3d with all default values:

AviSource("Blah.avi")
hqdn3d(ls=4.0, cs=3.0, lt=6.0, ct=4.5, restart=7)
