Step 2: Trim and Adjust Audio Timing

1. Drag the audio clip on the timeline to align it with your video.
2. Use the split tool to cut unnecessary parts of the audio or adjust the timing.
3. If syncing a voiceover, make sure speech aligns with the visuals, such as lip movements or actions in the video.
