The footage to gather

  1. The opening screen
  2. One deliberate tap sequence
  3. The useful result

Give each moment a little breathing room. Get close enough to show the detail, and keep the original clips handy.

Plan a release announcement

Opening

Show the old friction before the new interaction.

Middle

Put the changed experience side by side with the original task, keeping the feature scope clear.

Ending

Explain who can use the feature and where to begin.

Review it for mobile apps

Use readable crops without obscuring the navigation a user must find.

Ask yourself: Can a viewer distinguish a new capability from a visual refresh?

Watch it as if you were seeing it for the first time. If something is unclear, try a different cut or add the missing shot.
