Stock b-roll has a recognition problem: your audience has seen that same drone shot of a city at dusk in a hundred other videos, and familiarity reads as filler. Generated b-roll flips the economics - instead of searching a library for a clip that approximately fits your sentence, Reeloop generates a scene for the sentence. The shot planner reads your script line by line, briefs Seedance on a cinematic shot for each one, and holds a style bible across all of them so the footage looks like one production. Voiceover and word-timed captions are layered on, and everything ships as a single MP4. The honest framing: you're not getting loose clips for an editor - you're getting the finished b-roll-driven video.
B-roll has two jobs: literal illustration (the script says harbor, you see a harbor) and mood-setting (the script says everything changed, you see weather turning). Strong videos alternate between the two; all-literal feels like a slideshow, all-mood feels vague. Cut on narration beats - a new shot when the sentence turns - because visual change is what re-arrests drifting attention. Variety of shot scale matters too: wide establishing, medium, close detail, repeated in loose rotation, is the grammar viewers unconsciously expect from produced video. The failure mode to avoid is aesthetic drift: b-roll pulled from different sources with different color, grain, and lighting reads as cheap even when each clip is individually good. Consistency across shots is worth more than the quality of any single shot - it's the difference between footage and a look. That's exactly the problem a locked style bible exists to solve.
The pipeline starts from the script, which is the right place for b-roll decisions to live. Claude writes or adapts the narration, then the shot planner walks it line by line and briefs Seedance on one scene per line - subject, framing, mood - under a single style bible that fixes palette and visual character for the whole video. That per-line mapping is what makes the b-roll feel intentional: the visuals turn when the narration turns, automatically. Choose Documentary style for the classic narrated-over-footage feel, or Educational for cleaner explainer framing. One of nine AI voices reads the script, Whisper times karaoke captions to the audio, and the assembled MP4 exports in 9:16, 1:1, or 16:9. A standard 30-second video costs 3 credits, and the free trial video is enough to test whether generated b-roll beats your current stock-library workflow.
Whole niches run on narration-over-b-roll: finance explainers, luxury and lifestyle pages, geography and how-it-works content, documentary shorts. What they share is that the b-roll is the production value - there's no presenter to carry weak visuals - so visual consistency across an entire channel becomes the brand. Keep one style bible aesthetic across uploads and your channel develops the recognizability that random stock never delivers. Cadence norms in these niches run daily to a few times weekly, which Series mode can sustain: set the topic theme, review each generated video, and publish to connected accounts in one click. Mistakes to avoid: visuals that contradict the narration (viewers notice instantly), recycling the same establishing shot until it becomes wallpaper, and treating b-roll as decoration for a weak script - footage amplifies a script, it cannot rescue one. Start from the writing; the shots will follow it.
