In the paper, results of experimental research on wavelet video codec are presented. The author has put emphasis on the optimal selection of the coder parameters to optimize the coding time. The author has used six test sequences (Basket, City, Crew, Harbour, Ice and Soccer in 352x288, 30 fps) for the experiments. The sequences used in the research are commonly used to assess the effectiveness of video sequence compression. The measurement of the image quality is based on the PSNR. The results of optimal selection of wavelet video codec parameters due to the coding time are presented. The main goal of the paper is to show the coder parameters that provide the best values of the PSNR for a reduced coding time
