The footage to gather

  1. The old friction
  2. The revised interaction
  3. The task completed

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

Plan a first-session lesson

Opening

Explain what the user needs ready before beginning.

Middle

Group setup into a few checkpoints and pause on any choice that affects the result.

Ending

Point to the first useful action after setup.

Review it for product teams

Use a clearly labelled prototype if the feature is not released.

Ask yourself: Can the user tell what is required and what can wait?

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.
