What it does
Briefer is the bridge between a video-ad creative pipeline and IntroGen, a Remotion-based programmatic motion-graphics studio. It reads the upstream creative output - the campaign brief, the scored angle map, the hook bank, the script pack, the production plan - and translates it into the only thing IntroGen actually accepts: a brand URL, a video type, and producer direction. The translation is the point. IntroGen is not a generative video model: you cannot hand it shot beats, continuity kits or per-second timing, and every claim in the film must trace back to a fact on the brand's own site or the studio's fact-gate rejects it. Briefer maps angle families to the right video type, folds banned elements, do-not-say lists and compliance constraints into a single avoid list, classifies each claim as safe, direction-only or droppable, and declares plainly which upstream decisions cannot cross the boundary. It is deliberately conservative at the gate. It shows the complete mapping before anything is triggered, plans one production per approval, answers the studio's blocking questions only from the pipeline documents, and plans a half-resolution preview before any full render. It is honest about delivery too: the rendered file stays on the operator's machine, so the record surfaces posters, stills, file paths and a review link instead of pretending it can hand over the film. Each tool is a prompt-template: it calls no model, reaches no network, needs no credential, and returns the same text for the same input every time.
Turns approved ad creative into an IntroGen motion-graphics brief. Every claim checked, one production per approval.
