How do I update the narration on a presentation without re-recording the whole thing?

Use slide-level narration files so you can regenerate only the sections that changed.

The most efficient setup separates script blocks and audio by slide or segment. When one feature description, screenshot, or pricing detail changes, you edit that section and regenerate only that clip. This avoids the common full-take re-record cycle that slows teams down.

In practice, keep a predictable naming structure, such as intro, problem, workflow, proof, pricing, and CTA. This makes updates easier for both content and sales teams because everyone knows where each part lives.

You should also preserve timing controls at the slide level. A quick update should not force re-timing the rest of the deck. Systems that couple timing across the whole presentation create unnecessary overhead.

If updates are frequent, use version checkpoints. That gives you rollback safety when a last-minute edit creates mismatch between slide visuals and narration text.
