The footage to gather

  1. A draft listing
  2. Adding an image and option
  3. The product preview

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

Plan a single-task walkthrough

Opening

Name the user task and show the required starting state.

Middle

Record the action in sequence and explain only the controls needed to finish it.

Ending

Show the confirmation state that proves the task is complete.

Review it for ecommerce apps

Make it clear whether the example is a draft, preview or live store.

Ask yourself: Can a new user reproduce the task from the recording?

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.
