“instead of going straight into filming after a script I go through my entire script and annotate it with exactly what is going to happen on screen during each of those times whether that be b-roll or a visual or an or an animation or talking head footage”

Pre-edit the script with visual annotations

Insert a visual-annotation pass between script and camera: mark every line with the b-roll, animation, or graphic that will accompany it. Filming captures exactly the footage editing needs, you avoid "I wish I had b-roll of X" regrets, and the final cut is more dynamic. Front-loads the mental editing cost; turns the editing day into pure execution.
