The footage to gather

  1. The surface before treatment
  2. The cleaning step
  3. The same surface after drying

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 car detailers

Keep camera position and lighting comparable and name the service level.

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.
