FAQ

Add AI Narration to YouTube Videos — FAQ

Something not covered here? Contact us · support@vocallab.ai

Can I add narration after the video is already edited?

Yes, write narration to match the timing of your finished cut and generate it in the same sections, so it drops into the existing edit rather than dictating a new one.

What if a section of narration runs too long for its part of the video?

Adjust the speed for that section and regenerate just that piece, keeping the rest of your narration untouched.

Does this work for silent b-roll that needs a voice added?

Yes, write narration that follows the footage's pacing and layer the exported audio underneath the existing visuals.

Can I regenerate one section without redoing the whole video?

Yes, each section generates separately, so a timing change in one part doesn't require regenerating the entire narration.

Is post-production narration covered for monetized videos?

Yes, all generated narration carries full commercial rights, including videos added to an already-monetized channel.
