Turn a screen recording into a gaming product Demo in 30 seconds
A prompt recipe built from real briefs ngram users write for indie games, TTRPG tools, and game companion apps. Drop in your product URL or recording and generate a clean social demo.
What this template is
A gaming product demo video template is a slot-ified prompt plus scene structure that turns a screen recording or product URL into a 30-second demo for a game app, TTRPG tool, or gaming companion. ngram builds the four-beat shape — hook moment, feature walkthrough, outcome, CTA — so an indie developer or gaming tool builder only has to name the product, the hook, and the one feature to show. The template covers social formats where most gaming launches happen: X, Instagram Reels, and TikTok.
The template prompt
Copy it, replace the brackets with your product details, and paste into ngram — or click "Use this template" to open the editor with it prefilled.
Create a 30-second product demo video for [product-name], a [product-type] for [audience]. Use my uploaded screen recording (or pull screens from [product-url]). Open on the hook: [hook-moment] — the moment in the game or tool where the magic happens. Walk through [key-feature], narrating each step against the real UI or game screen. Do not fabricate fake UI. Tone: [tone]. End on the product name with the line [cta]. Visual style: motion graphics with on-screen callouts. If no voiceover, use captions plus background music suited to the game's genre.
| Slot | What to put | Example |
|---|---|---|
| [product-name] | Your product or game name | Lore Weaver |
| [product-type] | What it is | TTRPG campaign-wiki tool |
| [audience] | Who it's for | D&D dungeon masters and TTRPG players |
| [product-url] | URL to pull screenshots from (if no recording) | https://loreweaver.app |
| [hook-moment] | The opening moment — the in-world or in-product beat that grabs attention | a question asked by a player that the AI answers from session notes in under 3 seconds |
| [key-feature] | The one feature you demo | auto-generated illustrated character cards from session notes |
| [tone] | Voice and visual feel | atmospheric, fantasy-tinged, calm narration |
| [cta] | Closing line | Your campaign. Remembered. |
What the template builds
Four beats, 30 seconds — the structure gaming demos in the prompt cluster converge on.
- 1
Hook moment
6sOpen on the specific in-world or in-product moment that stops the scroll. No product name yet, no UI tour — just the compelling thing.
- 2
Feature walkthrough
16sCut to the real screen recording or URL-sourced UI. Narrate the one feature solving the hook, step by step, with on-screen callouts pointing at the actual product.
- 3
Outcome
5sShow the result the feature delivers. For a gaming tool, this is the thing the player or GM can now do that they couldn't before.
- 4
Product name + CTA
3sLand on the product name and closing line. Match the aesthetic of the game's genre — spare is usually stronger than flashy.
Make it yours
Duration
15 seconds for a teaser or social ad; 45 seconds to fit a second feature or a fuller walkthrough.
Narration
AI voiceover tuned to the game's tone, or captions-only for X autoplay where sound is off.
Visual style
Motion graphics with callouts for tool demos; minimalist for companion apps with a clean UI; immersive for games with strong world-building.
Aspect ratio
16:9 for YouTube and website; 9:16 for Reels, TikTok, and X; 1:1 for feed posts.
Common variations
In-world hook cut
Open with a question, challenge, or event from inside the game world — then reveal the product that handles it. Works for TTRPG tools and AI game companions.
Open the first 6 seconds in the game's world: show a real question or challenge the player faces. Reveal the product solving it at second 7.
Silent X/Twitter cut
No voiceover. Text overlays carry the story for X autoplay where most users never turn sound on.
Remove voiceover entirely. Use bold, short on-screen text (max 6 words per card) and light ambient music matching the game genre.
Fan-app minimal demo
For game companion apps with a deliberately simple UI: strip back the callouts and let the clean product speak.
Minimalist style. No animated callouts. Use text cards between clean product screenshots. Keep the palette close to the source game's color scheme.
45-second feature pair
Demo two features back-to-back for a launch post that needs to justify the depth.
Extend to 45 seconds. Walk through [key-feature] first (16s), then [second-feature] (14s). Single outcome beat covers both.
