This post documents Week 1 of a research project I call TopicWatchdog: an end‑to‑end, reproducible pipeline that (a) collects German political short videos, (b) transcribes them, (c) extracts topics and claims with timestamps, and (d) persists everything in BigQuery for transparent, long‑term analysis.
The focus is on methods and reproducibility, not on polished production code. The snippets below are meant as guidance scaffolding, but already allow you to build a similar pipeline.
