entranshqdn3d

This filter aims to reduce image noise producing smooth images and making still images really still (This should enhance compressibility).

Depending on high-quality setting, it runs either mplayer's hqdn3d filter algorithm or the denoise3d algorithm, which is cruder and simpler, but also faster.

Leaving or setting any of the other parameters to 0 will make the filter use the indicated internal defaults. Setting some parameters will also have this value 'trickle' into the other parameters as follows:

luma_spatial --> luma_temp, chroma_spatial, chroma_temp
chroma_spatial --> chroma_temp
luma_temp --> chroma_temp

In addition, setting a components (both) parameters to a negative value will not have the filter applied to this component.

Also used in transcode; denoise3d filter somewhat optimized [Erik Slagter]
