Screenshots in.
Demo video out.
Drop in PNGs, mark the regions you want the camera to land on, write a short outline. DemoScreen scripts the voiceover, beats the cuts to music, and emails you a 1080p MP4 with captions — most 60-second demos land inside half an hour.
Launch videos, onboarding walkthroughs, internal training videos for your team, feature-update clips — anything a screen can show.
Five steps.
One pass.
The studio walks you through each step in order, one thing at a time. The video above shows all five on a real project; here is the same walkthrough, written down.

- step 01Screens
Open the studio, press New project and drop in your screenshots in the order they should play. Each one becomes a scene.
- 8 to 14 screenshots suit a one-minute video. PNG or JPG, up to 8 MB each.
- Pick a look — Midnight, Keynote, Glass, Terminal or Paper — and a format: landscape 16:9, vertical 9:16 or square 1:1.
- Drag on a screenshot to mark up to four highlights. Each becomes its own close-up scene; a short label tells the narrator what's special there.
- The live preview shows your screens inside the template before a word is written.
- step 02Script AI
AI reads the text on your screens and writes a first draft, one line per screen. That text becomes the narration.
- Edit anything in the box, or type a few notes and press Rewrite with AI.
- Say who the video is for (optional) — it shapes the tone.
- Choose a length from 0:30 to 3:00. One minute suits most demos; Free renders up to 1:00, Starter 1:30, Pro and Team 3:00. The narration is written to fit.
- step 03Sound
Pick a voice and the music that plays quietly under it. Play a sample before you choose; both can be changed at any time.
- Free includes six voices and four music moods; Starter opens every standard voice and the whole library.
- Pro and Team add the premium narrators and let you describe a custom track instead of picking one.
- The mix is levelled to broadcast loudness (EBU R128) automatically.
- step 04Brand
Put your brand on the end card: the last four seconds show your product name, a headline and your website.
- Upload a logo and set an accent colour; the end card preview updates as you type.
- Turn on subtitles in the video if you want them burned in. An SRT caption file comes with every video either way.
- step 05Video AI
Check your choices, press Write scenes with AI, review every scene, then Make video. Close the tab — we email you when it's ready.
- Every scene gets a title, a subtitle and a narration line. Edit any of them, or rewrite one line at a time.
- The live preview plays your scenes in the real template before anything is rendered.
- Rendering takes a while — the length picker shows the estimate for each length. The video waits on your projects page when you're back.
- You get a 1080p MP4 (with a small demoscreen.co watermark on Free), an SRT file, a GIF of the opening and a share link. You're charged for the length it really runs — a failed video costs nothing.
What comes out.
Demos we made from plain screenshots of invented products — a web app, a phone app, a developer tool, a square social post and a long-form explainer. Different template, format, voice and music each time. Every one is the real render, not a mock-up.
