Explainer vs demo vs walkthrough: which does your SaaS need?
3 min read · Updated June 17, 2026
Three formats get lumped together as "the product video," and picking the wrong one wastes the budget. Here's what each does, and which one your SaaS actually needs right now.
Explainer
A short, scripted piece, around sixty seconds, that sells the idea. It answers "what is this and why should I care" for someone who has never heard of you. It lives on the homepage, the launch, and the ad. It uses motion graphics and a rebuilt UI moment, not a full tour. This is the format that lifts top-of-funnel conversion, and it's what most SaaS needs first.
Demo
A longer, guided look at the product in action, usually two to five minutes. It answers "how does this work for my use case" for someone already interested. It belongs deeper in the funnel: a sales follow-up, a pricing page, an evaluation. A demo is not a homepage hook. Put one up top and most visitors leave before the value lands.
Walkthrough
A screen recording of the real product, often narrated, showing actual clicks. It answers "show me you actually doing it" for an evaluator or a new user. It's the most credible and the most production-dependent, because it needs real footage from the live product. We treat it as an add-on, fed by a recording you send against a short shot list, for the reasons in how to brief an explainer video.
Which one first
| Your goal | Format |
|---|---|
| Lift homepage or launch conversion | Explainer |
| Help interested buyers evaluate | Demo |
| Show the real product in use | Walkthrough |
For most funded SaaS, the order is explainer first, then a demo or walkthrough once the top of the funnel is working. Start with the piece that decides whether a stranger sticks around. The full method is in the complete guide, and you can start an explainer here.
