The footage to gather

  1. Two sizes beside a familiar object
  2. Staff demonstrating the fastening
  3. The item packed with care instructions

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

Plan a three-episode series

Opening

Choose one question for each episode before filming.

Middle

Use episode one for context, two for the process and three for the result; give each its own ending.

Ending

Name the next question rather than asking viewers to watch an unexplained part two.

Review it for pet shops

Show sizing and intended use clearly; do not imply a product is suitable for every animal.

Ask yourself: Does each instalment add information rather than repeat the same montage?

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.
