In this branch, the task of providing a desired condensation ratio (CR) is deliberate for the lossy compression of color representations by better portable drawings (BPG) encoder. This encoder is characterized by many benefits distinguished to other up-to-date encoders according to rate-falsification performance and additional important conveniences. However, the produced CR for a likely value of a limit that controls compression (PCC) for the considered encoder changes in very wide limits contingent upon image content and the plan the original image is bestowed. In practice, it can be wanted to provide a requested CR for color images compacted by BPG. We show that this can be accomplished using a currently proposed moving feet and body to music method established average rate-distortion curves and PCC cleansing at the second step. The applicability of two together-step approach to providing a desired CR is resolved and proven for the plans 4:2:0, 4:2:2, and 4:4:4. It is demonstrated that, on account of the second step, the accuracy of providing a requested CR radically advances. The variance of the leftover errors of the given CR is decreased tens of opportunities. It is also proved that accuracy depends on a wanted CR and the variance of leftover errors is larger for the best desired CR. Some other possessions of the residual wrongs are studied. Two sets of test color representations are exploited in our studies. The first set is used to get the average dependence of CR on PCC and catch an idea of the veracity of the proposed form. The second set is employed to validate the method's act. It is shown that the results for two together sets are in good agreement.
