How long should a SaaS explainer video be?

"How long should it be?" is usually the first question on a discovery call. The honest answer is: as short as the job allows — and the job depends on where the video lives and how much the viewer already knows when they press play.

Start from the placement, not the script

The same product needs very different films for different moments in the buyer's journey.

• Social and paid ads. Viewers did not come for you, so the hook has to land immediately and the whole idea should fit in a few seconds of attention. Short cuts of 6–30 seconds work best, ideally several variations.
• Homepage hero. The visitor is curious but not committed. Aim to communicate the core promise in well under a minute, often as a muted loop with captions.
• Explainer on a landing page. The viewer is actively evaluating. One to two minutes gives room for problem, solution and the key workflow.
• Product demo or onboarding. The viewer has already decided to learn. Here length follows the workflow — clarity matters more than brevity.
• Launch film or conference opener. This is a brand moment. Pace and emotion matter as much as information.

A simple test for every scene

When we storyboard, each scene has to earn its place by answering one question: what does the viewer understand after this scene that they did not before?

If a scene repeats a point, shows UI without explaining why it matters, or exists because "the client asked for the feature to be in there", it goes. The film gets shorter and, almost always, clearer.

Length is a symptom. A long video usually means the story has not decided what it is about yet.

Structure beats duration

A tight explainer usually follows the same spine, whatever its length:

1. The problem your buyer recognises — stated in their words, not yours.
2. The shift — the moment your product changes the situation.
3. Proof through the product — one or two workflows shown with purpose, not a feature tour.
4. The outcome — what life looks like with your product.
5. The next step — a single, clear action.

You can compress that spine into a 30-second cut or expand it into a two-minute walkthrough. The order stays; only the depth changes.

Make one film, cut several

The most efficient approach we see is to design a master film and plan the shorter cuts from the start: a 60–90 second explainer, a 30-second promo and a few 6–15 second social edits that reuse the same scenes, styles and assets.

Planning cutdowns at the storyboard stage costs almost nothing. Retrofitting them after delivery often means re-animating scenes that were never designed to stand alone.

Our default recommendation

If you need one number to start the conversation: for a landing-page explainer, plan for 60 to 90 seconds, then challenge every scene. For ads, plan variations, not one long video.
