The Talking-Head B-Roll

[PERSON — generic, not a real individual] is shown in
[SETTING — e.g. their workspace], occupied with [SIMPLE
ACTION — e.g. reviewing notes, looking toward a window].
No speaking to camera; this is silent b-roll to cut under
a voiceover.

Camera: [SHOT SIZE — medium], slightly off-axis so the
subject is not centred. A slow drift, or locked off.
Eyeline off-camera, never into the lens.

Lens and light: [FOCAL LENGTH — e.g. 50mm], shallow depth
of field separating subject from background. Soft key from
a window at camera left, gentle fill, a faint rim from
behind.

Tone: warm, credible, editorial. Natural grade, true skin
tones, soft contrast.

No lip movement or speech. No text. No hands doing precise
work. No direct eye contact with the camera.
