A lecture film has a job most films do not: it must support a speaker without replacing them. Timed to the slot, cut to leave room for the room, and built so a pause lands where the speaker wants it.
Clinicians presenting at congresses, universities and training days — and the manufacturers who sponsor them. If you have a slide that never quite explains the mechanism, this is the thing that replaces it.
A film that narrates over the speaker turns the speaker into an usher. If the brief is a self-contained explainer with voiceover, that is procedure animation, and we would point you there instead.

The earlier in the writing this starts, the more the film can carry.
