render-split-screen-creator

Assemble a split-screen creator ad from a config: a two-zone vertical (1080×1920, 9:16, ~40s) format where an AI creator talking-head anchors the BOTTOM ~48% of the frame and real 16:9 product/demo clips run uncropped in the TOP ~52%, a 3px brand-color divider between the zones. The creator delivers the whole VO cold-to-camera and each top clip proves the claim its VO line makes. This capability is the FREE, deterministic assembly + captions — the two-zone composite (contain-fit + blurred-cover fill + divider + creator slice), the hard-concat, the end card, and the word-level caption burn from the assembled cut.

scripts/config.example.json is the worked example (Perplexity concept-10 "Bloomberg terminal", ~40s 1080×1920 9:16, 6 scenes + an end card); scripts/PIPELINE.md maps every config block to its source step and scripts/README.md documents the free assembly.
