Auto Synchronization
Using audio sync will make it effortless to match your audio with your video, making it sound clearer.
You try this feature by following the steps:
❶ Method 1. Select the Video + Audio with the audio track on the timeline simultaneously. Hover the mouse over the Auto Synchronization button on the toolbar above the timeline, and it will show tooltips to remind you of the function summary.

Note:
If you do not find the Auto Sync tab on the toolbar, click the Custom toolbar icon on the far left. You can drag the Auto Synchronization button into the toolbar.
❷ Method 2. Select the video + audio with the audio track simultaneously on the timeline. Click “Tools” on the menu bar and select “Auto Synchronization.”

❸ Method 3. Select the video (with audio) and the audio track on the timeline simultaneously. Right-click and select “Audio Synchronize.”

Note:
If the selected clips cannot be synchronized, a pop-up window will prompt, "The selected clips cannot be synchronized; please reselect the clip." Click "OK" to close the popup window.
❹ If you click the "Cancel" button, the audio and video will stop analyzing, and the pop-up window will be closed.
