Took the script only where the script was missing
Where approved scripts and recordings existed, we analysed and built on them. Where they didn't, we developed the script from the academic material first — logical flow, sequencing, learner comprehension — before any storyboard work began.
Made the storyboard the contract
Visual storyboards established exactly how narration would be supported: on-screen text, graphics, diagrams, illustrations, animation. Approving the storyboard meant approving the video, which is considerably cheaper than discovering a disagreement in post-production.
Kept visuals earning their place
The rule throughout was that a visual must add something the narration doesn't. A graphic that restates the sentence being spoken is decoration, and it costs attention that the difficult part of the lesson needs.
Varied the treatment by subject
Conceptual topics were carried by diagrams and illustration; process-heavy and information-dense sections got structured layouts and animation. Production standards stayed constant, visual approach did not.
