EN This paper presents a video encoding method in which noise is encoded using a novel parametric modelrepresenting spectral envelope and spatial distribution of energy. The proposed method has been exper-imentally assessed using video test sequences in a practical setup consisting of a simple, real-time noise reduction technique and High Efficiency Video Codec (HEVC). The attained results show that the use ofthe proposed parametric modelling of noise can improve the subjective quality of reconstructed videoby approximately 1.8 Mean Opinion Scope (MOS) points (in 11-point scale) related to the classical videocoding. Moreover, the present work confirms results attained in the previous works that the usage ofeven sole noise reduction prior to the encoding provides quality increase.
