B-roll
Finding, generating and placing cutaways that show what is being said.6 entries.
From a sentence to five search queries and one generation prompt
A prompt that turns each line needing a cutaway into five queries for your own footage or a stock site, ordered from literal to loose, plus one generation prompt as the fallback when nothing is found.
B-roll shot list from a transcript: the table to film or generate from
An agent prompt that reads a transcript and returns a shot table (timestamp, line, shot, source: have / film / generate) for a camera or a video model, grouped so each location is filmed once.
Cutaway matching: sentence to a literal visual, same place and time
A prompt that reads each sentence of a transcript and names the one picture that shows it, with the place and time it must come from, so the shot list is a list of things, not moods.
Generated b-roll or real: the decision rule
When a generated cutaway is fine (faceless, no logos, no claim about a real place or time) and when only footage from the same day will do. Five questions, in order, before you open a video model.
A mentioned object must be seen, ideally just before the line about it
The rule that turns 'X is mentioned, never shown' from a viewer complaint into a check you run on the transcript: every named thing gets a shot, placed just before or on the line.
Screen-recording b-roll for app demos: what to record, size, cursor
Rules for screen captures used as cutaways in a product video: real-looking data, output-size or 2x resolution, a slow cursor, one action per clip, and what makes a recording unusable.
