Why demos leak data so often

Real product environments are full of customer names, inbox previews, and tokens. Teams rush a capture for a launch and only notice the leak after the video is public. A screen recording blur tool lets you fix that without another take.

Blur workflow in VidLaya

  1. Upload the recording to the browser editor.
  2. Select Blur and drag over each sensitive region.
  3. Confirm the blur covers the full time those pixels are visible.
  4. Add zoom and highlight only after secrets are covered — overview in zoom, highlight, and blur.

Then finish the demo

Once privacy is handled, polish readability and ship. Start from the screen recording editor or the product demo video maker page depending on your goal.

Frequently asked questions

What should I blur in a product demo?

API keys, access tokens, customer emails and names, private URLs, billing details, and any production data that should not leave your environment.

Is blur better than re-recording with fake data?

Fake data is ideal when you can set it up quickly. Blur is faster when the recording already exists or the environment is hard to sanitize.

Does zooming make secrets more visible?

Yes. Always blur before or while you zoom into regions that contain private text, otherwise you enlarge the leak.
