Fine-Tune AI Video Voiceover

The video is already built in InVideo AI; only the voiceover needs a light touch. A handful of words and short phrases must be swapped with the new wording I’ve prepared, yet the synthetic voice is preferred to remain the same. Each time I try to change the script inside InVideo AI the timing drifts and the narration sounds unnatural, so I need someone who can make the substitutions cleanly and keep perfect sync with the visuals.

You’ll have access to:
• the current InVideo AI project link or export
• a script showing the precise lines that must be replaced

What I expect back:
• a final MP4 (same resolution as the original) with the voice correctly paced
• an updated source file so I can tweak future edits myself
Everything else in the video—music, graphics, transitions—should remain untouched.

If you’re comfortable wrangling InVideo AI or exporting the audio, editing it externally, and re-importing it so the timings line up flawlessly, this should be a quick win for both of us.
