🎤 How do I add or edit AI voiceover?

The Voiceover tab controls the narration for each scene. Edit the text, change the speaking voice, add emotional delivery, and regenerate the audio, all without touching the visuals. It has three tabs: Voiceover, Upload Audio, and Mirror Voice.

Generate AI Voice:

Under Voiceover:

1. Enter the Script (narration text for this scene).
2. Assign a Speaking Character (e.g., Rhea) to give the voice to a defined character.
3. Add emotion tags to control tone: Excitedly, Angrily, Calmly, and more.
4. Regenerate the audio.

💡 Tip: Stack multiple emotion tags for layered vocal delivery.

Upload your Audio

Under Upload Voiceover, click Upload your Voiceover to replace the AI voice with your own recording. Upload the narration separately for each scene or clip you want to update. Use the playback bar to preview before saving. The "Captions are from Voiceover" notice confirms captions auto-sync (and can still be edited).

You can also use a cloned version of your voice: provide a sample recording to have the voice cloned and added to your account, then use it for your videos.

How do I add or edit AI voiceover?

To change the voice a character speaks in:

1. Open the scene and go to the Voiceover tab.
2. Change the Speaking Character, or pick a different voice from the voice library.
3. Optionally set a Country Accent to match the tone you want.
4. Regenerate the voice for that scene. Changing a character's voice does not automatically update audio already generated in scenes; regenerate the affected scene audio. If the scene uses lip sync, regenerate the scene's motion/lip sync too, since it was created with the previous voice. Check the audio selected in the scene's lip-sync tab if the old voice still plays.

💡 To keep the same voice across every scene, set it once and use Mirror Voice → Sync Voice so the narrator stays consistent throughout the video. After syncing a voice change, regenerate audio in scenes that still use previously generated audio.

Keep one narrator across scenes (Mirror Voice)

Use Mirror Voice to maintain a consistent narrator tone across scenes: select the voice and country accent from the library, then click Sync Voice.

Tips

Here are some tips to get the best results:

• Stack multiple emotion tags for layered vocal delivery
• Use Mirror Voice to maintain a consistent narrator tone across scenes: Select the voice and country accent from the library and click on Sync Voice.
