You launched the app. Traffic hits the landing page and bounces.
Visitors will not read three screens of feature bullets. They want to see the outcome in under a minute. A tight explainer is the highest-leverage marketing asset you can ship without an agency invoice.
Ship a polished demo faster: Cubix Capture frames your app at capture time, auto-zoom on clicks, smooth cursor, staged backgrounds—so your explainer is share-ready when you hit stop. Get started free · Windows · Mac
This guide is the $0 path (script + native record + light edit). For full SaaS demo structure, see How to Record a SaaS Product Demo That Converts.
Step 1: Write the Pain-Solution script (under 60 seconds)
Treat the video like a salesperson, not a README.
| Beat | Time | Job |
|---|---|---|
| Hook | 0–10s | Name the pain in their words |
| Solution | 10–40s | Show the one "Aha!" workflow |
| CTA | 40–60s | One action: install, start trial, book demo |
Word budget: ~130 spoken words. One core workflow—not every settings screen.
Example hook: "Still chasing invoice status in three different tabs?"
Example CTA: "Start your free trial—link in the description."
Step 2: Record the app (free capture paths)
| Platform | Free option | Caveat |
|---|---|---|
| iPhone | Control Center → Screen Recording | UI looks tiny on desktop viewers unless you frame in edit |
| Android | Quick Settings → Screen record | Same readability issue |
| Mac | Cmd + Shift + 5 | Mic + system audio need explicit toggles (no audio fix) |
| Windows | Snipping Tool video or Win + G Game Bar | Set Audio to record: All if you narrate over UI sounds |
Move slowly. One finger / one click per idea.
Step 3: Assemble in a free editor (optional)
You may have: voice memo narration + screen clips.
- Import to CapCut or Canva Video (free tiers).
- Lay audio first, picture second.
- Trim loading states and false starts.
- Low-volume music bed (optional).
- Captions—most landing-page traffic is muted on mobile.
That stack works. It also hides a cost: manual zoom if the UI was recorded wide.

The hidden cost of "free" explainers
| Symptom | Why it hurts conversion |
|---|---|
| Bookmarks + tabs visible | Looks like a side project |
| Tiny UI on phone | Viewer assumes product is complex |
| Shaky cursor under zoom | Feels anxious, not confident |
| Hours of keyframes in CapCut | "Free" becomes expensive in founder time |
Agency polish is not magic—it is framing + calm motion + clean stage. You can buy that with time in an NLE, or with capture-time tools.
When to skip the edit bay: record with presentation capture
For web and desktop apps, record the Solution beat with Cubix Capture:
- Auto-zoom tracks clicks so buttons read on a phone
- Smooth cursor keeps motion presenter-calm
- Live backgrounds hide desktop noise
Optional post: captions or a tight trim in Cubix—not another full re-zoom project.
Quality checklist before you embed
- Hook names pain in first 5 seconds
- Only one workflow shown
- Text readable at 50% phone width (preview on your phone)
- CTA spoken and on-screen
- File under email/Slack limits (file size fix)
