Make a 30-second Demo video for any entertainment app
A prompt recipe built from the real briefs founders bring to ngram. Drop in your app, your screen recording or URL, and the one feature worth showing — ship a clean demo in minutes.
What this template is
An entertainment app product demo video template is a reusable prompt plus scene structure for turning a screen recording or product URL into a short, attention-grabbing walkthrough of one feature. It covers consumer and social apps — video chat, music tools, booking apps, social creative tools — where the hook matters as much as the feature. ngram builds the four-beat structure (hook, feature, outcome, CTA) so a founder only fills in the app name, the input, and the one thing worth showing.
The template prompt
Copy it, replace the brackets with your app details, and paste into ngram — or click "Use this template" to open the editor with it prefilled.
Create a 30-second [aspect-ratio] product demo for [app-name], a [app-category] app for [audience]. Use my [input-type] as the main visual source — do not invent fake screens. Open with [hook-visual] to grab attention in the first two seconds. Then show [key-feature] in action, narrating each step against the real UI. Tone: [tone]. End on the logo with the line [cta]. If no voiceover, use on-screen captions and background music.
| Slot | What to put | Example |
|---|---|---|
| [app-name] | Your app name | Waveroom |
| [app-category] | What the app does, in plain words | live video-chat |
| [audience] | Who uses it | people who want spontaneous video conversations |
| [input-type] | What you attach | screen recording |
| [hook-visual] | Opening frame — the image or moment that stops the scroll | two strangers connecting on screen in under three seconds |
| [key-feature] | The one feature you demo | AI-matched pairing by interest |
| [tone] | Voice and feel | energetic, playful, Gen Z |
| [cta] | Closing line | Try Waveroom free — meet someone interesting today |
| [aspect-ratio] | Output format | 9:16 for Reels and TikTok |
What the template builds
Four beats, 30 seconds — the shape real entertainment app demo prompts converge on.
- 1
Hook
4sOpen on the moment that makes the app feel alive — a match, a beat drop, a booking confirmed. No product UI yet; just the emotion or the problem.
- 2
Feature walkthrough
16sCut to the real screen recording or URL screenshots. Narrate the key feature step by step, with callouts on the UI elements that matter. No fake screens.
- 3
Outcome
7sShow the payoff: the connection made, the ticket booked, the beat published. One clear result.
- 4
Logo + CTA
3sLand on the app logo and the closing line. Calm but confident — end where the user should go next.

Duration
Shrink to a 15s tease or stretch to 60s for deeper walkthroughs.
Aspect ratio
Match where you're posting it.
Narration
AI voiceover for YouTube; captions-only for muted feed autoplay.
Style
Visual treatment behind and around the recording.
Common variations
Vertical social tease (9:16, 15s)
Drop the outcome beat and cut the walkthrough to one step. Built for TikTok and Reels where attention is three seconds.
Reduce to 15 seconds, 9:16. Keep the hook and one feature step only. Large centered captions. End on the logo.
YouTube channel demo (16:9, 30s)
Full-length desktop-format demo with voiceover for a channel or website hero section.
Output 16:9. Add a clear AI voiceover in [vo-language]. Include a lower-third with the app name on the first cut.
No-VO captioned cut
For feeds that autoplay muted. Captions carry the story; background music sets the mood.
Remove the voiceover entirely. Use on-screen captions — short phrases, not full sentences. Add upbeat background music.
Competitor-style demo
Use a well-known app's visual style as the motion reference while keeping your own brand and content.
Match the motion-graphics style of [reference-app] — similar pacing and visual rhythm. Apply [app-name] brand colors and logo throughout.
