The biggest source of this problem are E-300 cartridges because they use the thinnest video tape.Дebut video capture software displays the number of dropped frames at the end of the recording.ДЄnother reason for dropped frames is the incorrect handling of someД¬odecs when reading video streams containing NULL frames. But audio will be recorded without interruptions. Possibly this results in dropped frames in the video file, because sometimes the grabber cannot sync to destroyed frames. Wrinkled VHS tape leads to stroyed frames. Sudden offset due to image dropouts (Dropped Frames).This audio delay increases constantly with increasing running time of the video. As a result audio and video track diverge.ДЄlready 0.1% deviation of video speed lead to a an audio delay of 1s after 20 minutes running time. But the audio track is played with the same sampling frequency as it has been recorded. If the grabbed recording is played at a computer with exactly 25 fps this leads to an incorrect duration of the video track. As a result in VHS, the actual frame rate during playback is never exactly 25 fps. This is done automatically or manually via dial. VHS players compensate geometric variations of the mechanic tape flow by regulating the playback speed slightly until the image is properly synchronized. Audio delay as a result of the automatic video frame synchronization of the VHS player.In the properties window of your video file sometimes there are also shown different total run times of the audio and video track. Mostly the offset is increasing with the length of the video.
