1. A video encoding system comprising:

  • a visual perception estimator adapted to estimate a perception threshold for a pixel of a current frame of a videostream;

    an encoder adapted to encode said current frame;

    a compression dependent threshold estimator adapted to estimate a compression dependent threshold for said pixel at least from said perception threshold and information from said encoder; and

    a filter unit adapted to filter said pixel at least according to said compression dependent threshold.
