After UNlinking, here's an easy way to handle sync issues like this...
Split the video track only at the point where the bowing begins. Click the chevron to the right of the SPLIT BUTTON, under the preview window, and choose Video Tracks, then the specific track.
Then listen to the audio track and create a similar Audio Track only split where the sound begins. To hear audio when manually moving the scrubber (red line) on the timeline, click the AUDIO tab in the toolbar and click SCRUBBING.
Finally, line up the two splits, one above the other by dragging the audio track later (to the right). To eliminate gaps in a track, right-click in the gap and CLOSE GAP.
