More DSP Effects in Video Encoder

[RUDI_AUDIO]

Hello,
many movies are in Original too much dark and with the choosable "Brightness/Contrast" under "DSP" I can't get good results.
How is the format of the DSP Plugins ? Can I freely download them somewhere to get more or have they a special format which is only compatible for dB Video Converter ?
I would like to have a "Gamma" slide or/and better "Brighten Shadows an Darken Highlights". And a second saturation slider named "Vibrance".

with kind regards, Rudi

It is not possible to supplement the DSP effects.

I will look into the points you have raised.
