The footage to gather

  1. The starting task
  2. The uninterrupted demonstration
  3. The visible result

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

Plan a one-minute pitch

Opening

Use the opening ten seconds to establish the problem.

Middle

Reserve the middle for a real demonstration or a dated piece of evidence; cut secondary claims first.

Ending

Use the final seconds for the ask and a way to follow up.

Review it for product demos

Keep cause and effect intact and do not edit around a limitation that affects the claim.

Ask yourself: Can the pitch fit the intended time without rushing its evidence?

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.
