1. Press Shift + A or click Add in the Video Sequence Editor.
2. Select Sound and browse to your audio file (voiceover). This will add your narration into the timeline.

---

Step 4: Match Visuals with Audio

• Scrub Through Audio: Move the playhead through your audio track to listen and find key moments where certain visuals should appear or move.
• Add Keyframes for Sync:
1. Select an object (e.g., text or shape) in your scene that needs to sync with the audio.
2. Move the playhead to the exact frame where the object should appear or start animating.
3. Press I to add a keyframe for the object (you can keyframe properties such as location, rotation, or visibility).
• Adjust Timing: Use the timeline and move keyframes forward or backward until the visuals match the narration perfectly.
• Tip: If you have multiple objects to sync, break down the audio in sections and animate each section one at a time.

---

Step 5: Fine-Tuning Sync

• Add Transitions or Delays: To make transitions between visuals smoother, consider using Blender’s animation easing functions (like Ease In/Out) to make visuals appear or disappear gently.
• Visual Cues for Important Points:
1. Add emphasis to critical points in your narration by animating visual effects such as highlighting a text, zooming into a diagram, or changing the color of a flowchart element.
• Test Playback: Play your animation with audio multiple times to see if everything is perfectly in sync.

---

Step 6: Adjust Audio Timing (If Necessary)

• Trim or Shift Audio: If necessary, go back to the Video Sequence Editor and adjust the audio by moving it left or right on the timeline or trimming unnecessary parts.

---

Step 7: Export the Final Animation with Audio

• Set Output Format: In the output properties (right-side panel), set your render format to an appropriate video format like FFmpeg for video and audio. Choose MPEG-4 under the Encoding options.
• Render: Once everything is synced perfectly, go to Render > Render Animation to export your animation as a video with synced audio.
