Do I have to rebuild my deck from scratch?

No, you should not have to rebuild from scratch if the tooling is set up correctly.

FQO.US imports your existing PowerPoint or Google Slides deck and treats narration as a separate layer. Fonts, brand colours, animations, and embedded media survive the import. For most teams the first deck is live within an hour, including script editing and a single regeneration pass.

The bigger gain is what happens after the first deck. Because narration sits on top of the slide rather than baked into a single MP4, you can change one slide and regenerate only that voiceover. A pricing update that would take 30 to 45 minutes of re-recording in a traditional video editor takes two to three minutes here. The deck itself stays in your existing source file, so your design team is not duplicating work.

If your current deck is built for live presentation, expect to make small structural tweaks rather than a rebuild. Common adjustments include splitting dense slides into two, removing speaker-only build animations, and adding explicit section markers so async viewers can navigate. These usually take 10 to 20 minutes per 10 slides.

Guided demo flows can help if you need to add interactive choice points such as "see the analyst view" versus "see the executive view". This is the only case where light rebuilding may make sense, because you are adding navigation structure that did not exist in the live version.

Avoid the trap of rebuilding for perfection on the first pass. Ship version one, watch the analytics, then refine the three or four slides that viewers drop off on.
