How to explain an app feature as a step-by-step video
Describe the flow step by step and tell Vizard Agent which app it belongs to. Vizard Agent researches the product, records the narration, builds each interface screen as clean vector graphics rather than a generated screenshot, and corrects the product name in the transcript before captions exist.
What do you type into Vizard Agent?
Write the flow out as numbered steps rather than as a paragraph. Vizard Agent turns each step into its own scene, with its own interface screen and line of narration, so a numbered description is both the script and the storyboard. Spell the product name out, because transcription will guess otherwise.
Prompt
What does Vizard Agent actually do?
Explaining a feature nobody has used yet means showing the interface, and you rarely have a recording of the flow you are describing. Building the screens as vector graphics gives you a clean, on-brand version of the interface without needing to capture one. In the session behind this article it:
- Searched for the app to ground what the video says about it, generated the narration, and searched for stock footage and music.
- Transcribed the narration for word-level timings and corrected the product's spelling in the transcript before any caption was generated.
- Generated the scene visuals and sound effects concurrently, reviewed them as a montage, and measured the voice and music loudness.
- Built a test card renderer and preview frames for all four scenes, fixing the colour conversion when the first preview came out wrong.
- Rejected the generated interface screens, built a custom vector icon module and re-rendered the scenes with it, then regenerated the captions at a refined size and position.
- Reviewed a quality-control montage and delivered 1080x1920 at 30fps, 31.0 seconds long.
When does this not work well?
This format shows a clean, idealised version of your interface. Vector screens are a representation, not a capture of your app, and explaining an unbuilt feature as if it ships is a promise. Research is shallow for new products, because Vizard Agent grounds what it can find publicly. Four steps is the comfortable limit for one video.
Common questions
Do I need a screen recording? No. Vizard Agent builds every interface screen as vector graphics from your written description of the flow.
Will Vizard Agent get our product name right? Yes, if you spell it out. It corrects the transcript before generating any captions.
How many steps fit in one video? Four is comfortable in thirty seconds. More needs a longer video or a series.
