The included matrix dll files can be used to raise bitrate at dark scenes.

4 dll's are included:
- matrix1.dll	mild raise
- matrix2.dll	moderate raise
- matrix3.dll	heavy raise
- matrix4.dll	hits dark scenes real hard...

Copy one of these in the HCenc directory and rename it to matrix.dll.
In HCgui activate the 'adaptive matrix' checkbox in the matrix tab.
It can also be activated by manually adding *ADAPTIVEMATRIX to the HC.ini file.
You probably need to copy the DFORRT.DLL in HCenc as well.

How it works:
Depending on the average luminance per GOP the matrix which was set as default
will be adapted so more bits are allocated to dark scenes.
This means the intra and inter matrix may be changed every GOP depending on
the source (luminance) content.

NOTE:
The internal *LUMGAIN command will do about the same, settings are a bit different.
