Introduction

The High Quality 3D Denoiser filter aims to reduce image noise producing smooth images and making still images really still (This should enhance compressibility).

Parameters

User Comments

I highly recommend using this filter with animated material. It improves the image quality and reduces the output file size. -Phil

NOTE

For a decimate-with-filtering type denoiser more suited to live-action, see the nr option in ffmpeg.cfg.
