Inside Plot's AI Narration: How Voice and Pacing Are Auto-Generated
product
A closer look at how Plot writes the script, picks a voice, and paces scenes so your slides become a watchable narrated video.
Most "presentation to video" tools stitch slides together and leave you to record a voiceover. Plot does the narration work for you. Here's what's actually happening under the hood.
Script generation from slide context
Plot reads the text, headings, and visual hierarchy on each slide or screenshot. It infers what the scene is trying to say — a feature, a benefit, a step — and drafts narration that matches that role instead of just reading bullets aloud.
Scene pacing tied to content density
A title slide gets a short beat. A screenshot with five annotated points gets more airtime. Plot allocates duration per scene based on how much there is to say, so the video never feels rushed or padded.
Voice selection and delivery
You choose a voice; Plot handles the delivery — pauses at transitions, emphasis on product names, natural intonation on questions. Swap voices at any point and the entire video re-renders in sync.
Music that ducks under narration
Background music is mixed with automatic ducking so the voiceover stays clear. No manual audio leveling.
Editable, not locked
Everything the AI drafts — script, timing, voice, music — is editable per scene. You keep control; you just skip the tedious first pass.
