The structure that works
Most demo videos fail by touring every feature. Buyers don't care about features; they care about the moment their problem disappears. Show that moment early, ideally in the first 20 seconds, then show the two other moments that make the product worth paying for.
Keep one call to action. If the video ends with 'start a free trial, book a demo, follow us and read the docs', viewers do none of them.
- 0 to 10s: the problem in the viewer's words
- 10 to 90s: three product moments
- 90 to 120s: proof
- Last 5s: one call to action
Live recording vs. scripted voiceover
Founders often record demos live because it is fast and authentic. The trade-off is polish: hesitations, fast cursor movement and small mistakes. A middle path is to record live for timing, then let an AI tool clean up the narration or re-voice it from a tightened script, keeping your pacing and clicks.
Making many versions without re-recording
Once a demo works, teams want variants: a shorter cut for ads, a version per persona, versions in other languages. Re-recording each one is where demo videos go stale. In Explaino you can edit the script and regenerate the voiceover, translate the whole video, and export different lengths from the same project.
