First, Happy New Year to everybody
I notice errors in the french translation but I checked the english, there is the same errors with the filter HQDN3D.
To easier identifie this problem I set values to 1.0 2.0 3.0 4.0 :
The filter works but texts are wrong, it should be something like :
Spatial luma strengh
Spatial chroma strengh
Spatial luma temporal
Spatial chroma temporal
