Promo video or demo video?
| Promo video | Demo video | |
|---|---|---|
| Goal | Get attention and interest | Show how the product works |
| Length | 15 to 30 seconds | 30 to 90 seconds |
| Focus | One benefit, one result | A few features in a flow |
| Where | Social posts, ads, launch pages | Landing page, sales email, onboarding |
A simple promo structure
Cut anything that does not serve those four. If you need to explain more, that is a demo, so use the SaaS demo video template instead.
- Hook: the problem or the result, in the first three seconds
- Benefit: one thing the product does, shown on the real screen
- Proof: a result, a number or a finished outcome the viewer can see
- Call to action: one next step and your web address
Where to use a SaaS promo video
- Product Hunt and other launch pages
- LinkedIn and X posts, where short videos get more attention
- Paid ads and retargeting, with a tall 9:16 version for stories and Shorts
- The top of your landing page, above the demo
- Release announcements for a new feature
How to make one with DemoVey
Because it uses screenshots, you can update the promo when the product changes without recording again.
- Upload two or three screenshots: your best screen and the result.
- Describe the product and add a note such as short promo, one benefit only.
- Pick a voice, a theme and your logo. Choose 9:16 for social or 16:9 for the web.
- Watch the result. Paid plans can download MP4, WebM or GIF and make new versions.
Questions
How long should a SaaS promo video be?
Fifteen to thirty seconds for social and ads. Up to forty five seconds for a launch page.
Can I make a vertical promo?
Yes. Choose the tall 9:16 format for stories, Reels and Shorts.
Do promo videos need a voiceover?
Most are watched with the sound off on social, so captions matter. DemoVey adds captions, and a voice for when sound is on.
