Apparent motion discontinuities in the videos, such as frame freezing and frame skipping, are a common temporal degradation in the video transmission via Internet and Mobile channels. The end-user perceives a fluidity break of visual information having an impact on his quality assessment of the delivered video sequence. A video subjective test based on SAMVIQ (Subjective Assessment Methodology for VIdeo Quality) [1] has set up to estimate the effect of frame freeze and frame skip on video quality. In this paper, we will present the subjective test which has already set up for the estimation of video quality, then we can deduce the different situations of frame freeze and frame skip distortion has different impairments on video quality.
