Product demo videos, built from your code

Why product demos need care

A screen recording captures one live session. DemoVexa instead uses your product context and code folder to plan a story and recreate the interface as an animation, so you can direct the explanation rather than repeat clicks on camera.

How DemoVexa makes a video

Connect a product workspace with its code, website or documents. Start a project with a one-line idea and review the generated brief. Edit the script and on-screen captions, choose an AI voice, your own recording or captions with music, then review the planned scenes.

Approve the scene plan to build an animated preview. Check the screens, labels and timing, ask for changes if needed, then render the formats and languages available on your plan. Export and publish the files yourself.

• The product UI is recreated from the workspace context; it is not a captured customer session.
• DemoVexa does not automatically refresh an existing video when code changes.
• Review product claims, sample data, captions and the final preview before sharing.

What to provide

Show one customer workflow from the first screen to a clear outcome. Use sample data in the scenes and check every label and claim before rendering.

Add a local code folder or a reachable website, relevant how-to guides or product documents, and a clear idea of the viewer and task. Select the platform and length in the project brief. If you use a repository, clone it locally and pull the version you want to show first.

What you can export

Export an MP4 in Landscape 16:9, Reel 9:16 or Square 1:1, depending on your plan. A project can also provide on-screen captions, timed SRT or WebVTT subtitles, cover images and draft post copy. Each format and language is rendered separately.

Example workflow

Show one customer workflow from the first screen to a clear outcome. Use sample data in the scenes and check every label and claim before rendering.

Treat this as a sample scenario, not a customer case study or a published DemoVexa video. Use synthetic data and verify the behavior against your own product before release.

Plan your next step

Choose the video type that fits the story, check which formats and languages your plan includes, and leave time to review the finished preview before publishing.

Choose the first product story

Start with a viewer who has one unanswered question: what can this product help me do? Pick a workflow that reaches a visible outcome, such as creating a report or inviting a teammate. A focused first video is easier to verify than a tour that tries to cover every feature.

Write the task in plain language before choosing scenes. Name the starting point, the action the viewer takes and the result they should recognize. If the result depends on a plan, permission or setup step, include that condition in the brief.

• Use a current code version and the matching product guide.
• Replace customer names, records and credentials with fictional data.
• Keep claims tied to a screen or approved source.
• Choose a format for the first publishing destination, then preview others separately.

How to review the finished product demo

Check the video as a product artifact, not only as a polished animation. Compare the recreated screens with the current app, verify each label and workflow transition, and listen for narration that promises more than the UI demonstrates. Ask the person who owns the feature to approve the final version.

The exported files are drafts for your publishing workflow. Confirm title, captions, cover, aspect ratio, accessibility and any third-party asset rights in the destination where the video will appear.

Write a brief that keeps the demo focused

A strong brief gives the production process a viewer, a task and a proof point. For example: a new operations lead needs to see how a sample workspace turns an incoming request into an assigned task. The proof is the completed task on screen, not a broad statement that the product makes every team more efficient. If you cannot name the screen or result that supports a claim, remove or qualify the claim before it reaches the script.

Add the intended audience and destination as well. A sales follow-up can assume the viewer has already met your team; a public landing-page video needs enough context to make sense on its own. Note any prerequisite such as an enabled plan or administrator permission, and decide whether the video should show that setup or simply state it.

• Audience: who is watching and what do they already know?
• Task: what one job should the viewer understand?
• Evidence: which screen or result proves the explanation?
• Boundary: what should the video avoid promising or showing?

Turn one workflow into a clear scene sequence

A product demo usually needs more than a sequence of clicks. Establish the starting situation, show the decision or action that matters, then let the viewer see the outcome. Keep transitions that explain why the next screen appears; omit navigation that adds no context. If a user chooses a date range before generating a report, show the choice and the report it changes. If a workflow has optional branches, choose the path relevant to the audience and mention other paths only when they change the outcome.

Review the script against the planned scenes before rendering. Product names, button labels and technical terms should match the current interface. Give narration enough time to explain a state before moving on, and use captions that remain readable in the smallest destination format you plan to publish.

Choose the right source and protect private information

A local code folder gives DemoVexa product context for rebuilding software screens. A website or product documents can also seed a project when the code is unavailable, but the resulting interface may be less exact. Add a focused help article or release note when the task depends on a particular sequence. These inputs help draft the story; they do not replace a product owner checking the final behavior.

Use invented organizations, names, emails and records in the brief and scenes. Remove tokens, API keys, internal URLs, customer screenshots and unreleased details from the material you send to an AI provider. DemoVexa does not upload the source folder to its own service, but relevant context is sent to the AI provider you select under that provider's terms.

Publish a version you can maintain

Treat the render as a dated product communication. Keep the approved brief, code revision or release reference, script and final exports together so the team can tell which story the video represents. Before publishing, check that the chosen aspect ratio suits the destination, captions are present and readable, the thumbnail does not expose sample information, and the call to action still points to the right place.

After a product change, compare the affected workflow with the published video. A new build starts from the updated code and a human-approved story; existing exports do not refresh automatically. Assign an owner to decide when a label change is harmless and when a changed permission, outcome or navigation path requires a replacement video.

• Record the product version and review date.
• Check captions, contrast and playback with sound off.
• Replace old embeds and downloads when the approved story changes.
• Keep an accessible transcript or written guide for viewers who cannot use video.

Choose the production approach for the audience

A source-built animation is useful when a team needs a composed explanation of a software workflow and can review the recreated interface against its product. A screen recording may be a better fit when the viewer needs to see a live environment, a fleeting behavior, or an authentic human demonstration. An interactive demo may fit when the audience needs to choose a path or inspect details at its own pace. These formats answer different questions; choose based on what the viewer must see and do.

Before committing to a larger series, make one representative video. Include the ordinary path and one important decision point, then ask a product owner and a person from the target audience to review it. Note what they misunderstood, whether the UI recreation is sufficiently accurate, and how many review rounds were needed. That pilot gives the team a grounded estimate of production effort without assuming every workflow will be equally simple.
