When we are making a movie file from screen captures and an audio stream, it happens some inconsistency problem between audio and video streams. The audio stream comes from a sound card equipped at a stand-alone PC, In this paper, we propose a new smoothing algorithm between frame intervals of video stream and audio stream. Our proposed method can control the number of frames of video dynamically to solve the inconsistency of one video and one audio stream. We explain implementation method for the algorithm and experiment the efficiency of AV-Timing. We examined the ratio of inserted frames of resulted video files in a unit time, frame insertion interval and correction ratio, etc. In experimental, we confirmed that our proposed algorithm is the method minimizing the lip-synch AV-Timing problems in recording computer screen and movie making.
