SaaS explainer videos made from a brief
ViralDub Motion makes SaaS explainer videos from a brief. Describe the product or the launch, add your website or a PDF if you like, and an AI motion designer writes the storyboard, records the voice-over, animates each scene in your brand colours and reviews its own frames before rendering. A 30-second Standard explainer usually takes 8 to 10 minutes, and your first 15-second video is free.
Key takeaways
- Input: a brief, plus your website or up to 2 PDFs and 6 images. Your logo, colours and fonts can be imported from your URL.
- The voice-over is recorded first and every scene is animated to it, so words and motion stay in sync.
- Formats: 16:9, 9:16 and 1:1, from 15 seconds to 5 minutes depending on plan, up to 4K on Pro.
- Edit any scene's text and only that scene re-renders. Translate a finished video in one click on Pro.
- Want your real interface instead of animation? Use an agent walkthrough.

How Motion builds an explainer
- 1
Brief and sources
"A 45-second explainer for our invoicing app: the late-payment problem, three features, one customer number." Add your site or a PDF and it uses your real wording and screenshots.
- 2
Storyboard
The AI writes the scenes and the script, sized to the length you chose.
- 3
Voice first
The voice-over is recorded before any animation, in any of 22 languages.
- 4
Scenes as code
Each scene is animated in code, synced word by word to the narration, in your brand colours and fonts.
- 5
Art-director review
The AI checks its own frames for overlaps, empty space and legibility and fixes them before the final render.
- 6
Edit and export
Change a scene's text and only that scene re-renders. Pro adds 4K and deck exports as PDF, PPTX and interactive HTML.

What makes a SaaS explainer work
- One problem, named in the first 5 seconds in the words your customers use.
- Three benefits at most, each tied to a feature shown on screen.
- A real number (time saved, customers, a result) if you have one. Leave it out rather than invent it.
- One call to action on the end card.
- A 15 to 30 second cut for ads and social, made from the same brief in 9:16 or 1:1.
