A deck that worked in a meeting room is not automatically a good video.
Narrated video keeps your visual design but adds a voice track viewers listen to without you in the room. Small layout changes make a large difference in watch time.
Design for listening, not reading
One takeaway per slide so the narrator can pause naturally
6 words per bullet on screen; details belong in the script
Full-sentence headlines only when the sentence is the point (policy titles, legal names)
Avoid animation-heavy builds that mean nothing without a live pointer
Charts, tables, and diagrams
Give the narrator one sentence of context before numbers appear
Simplify tables: split wide grids across two slides if needed
Label axes in the deck so the voiceover can reference trends, not read every cell
Export complex slides as high-resolution images before PDF if fonts look soft
PPTX vs PDF for narrated video
PPTX when instructional designers still edit copy in PowerPoint or Google Slides (export as PPTX).
PDF when the deck is locked after brand or legal review. Upload via PDF to Video.
Workflow after design
Upload to Presentation to Video
Draft spoken scripts per slide (generate, then edit stiff lines)
Preview awkward slides before full render
Optional: AI Soundtrack for a light underscore

Design once, narrate many times
Tighten slide copy, then export a narrated MP4 without re-recording when the message changes.
