Take 1Brief
A first exchange about the topic, who will watch and what the lesson should achieve. No camera runs before that is settled.
Take 2Script
The full text of each lesson or piece, with the order of topics, the planned length and the list of support material.
Take 3Recording and editing
Capture, cut, audio, captions and review at the editing desk, track by track, until the final version.
Take 4Release
Delivery in the agreed format, publication in the client's own environment and follow-up on the first responses.
No take starts before the previous one is approved. That is what keeps reshoots away from the end.
