The video quality and compression ratio depends on the GOP pattern structure (i.e. the I, P and B-frames). This paper studies the impact of  using different values for Frame Rate on GOP structure with respect to the number of consecutive maximal count of B-frame sequences to reach a better  video quality . A MATLAB code MPEG-2 algorithm was used to model and assess this effect. The assessment test was implemented using three types of reference videos: Foreman, News, and Football sequences in (YUV video repository). The Simulation Results show that using more B-frame sequences than that studied in previous work, with respect to Frame Rate (FR) causes an improvement in Video Quality (PSNR) irrespective to type of video Motion.
