Why product demo teasers suits AI video
A teaser sets a mood before you show the real thing. A cinematic scene and a one-line voiceover can introduce a feature or a launch, with the real product demo following in your own footage.
How to describe the scene
- The scene around the product, not the product itself
- A strong mood: sleek, playful, rugged, calm
- A single line of benefit for the voiceover
An example you can adapt
Example sentence: A sleek desk with a glowing laptop at night and a city skyline through the window.
Example voiceover: "Work that finally keeps up with you. Meet the new way to plan your day." That script is 15 words, so the video falls in the "6–10 seconds" length and costs 2 credits in Full HD or 4 credits in 4K.
Sound and camera
- Voiceover with the benefit, or Corporate or Energetic music
- Horizontal 16:9 for a launch page; vertical for ads
- 4K gives sharper detail on a large screen
Mistakes to avoid
- Expecting an exact demo of your software or device: text to video imagines a scene
- Showing screens or text, which the AI cannot render reliably
