Streaming of high-quality video contents as part of multimedia communication, has become essential nowadays. Video delivered over the network suffers from different kind of impairments, which degrades its quality. Such network impairments effect differs among different types of codec used. This paper present the effects of network degradation factors such as packet loss and jitter over H.264 and H.265 encoded video sequences. In addition to the codec used, we also focused on the different level of temporal and spatial aspect within the videos. Among different basic test methods, double stimulus impairments scale was used to complete the experiment as subjective measures of assessment metric from user’s perspective.The result illustrates that differently encoded video sequences react differently to the network impairments and are very sensitive to a transmission error. Similarly, it also shows that user’s experience is affected according to the motion level of video.
