What problem does it solve? Upgrading commercial short-film renders to a cinematic finish requires coordinating many scattered flags—dark-framed UI, SFX under VO, logo walls, tamper dwell timing—across beats JSON files and render scripts, and misconfiguring any one produces empty broll or broken audio mixes. ## Core Features & Use Cases - Cinematic finish enablement: Set cinematic_finish: true and polish.sfx flags in beats JSON to activate dark-framed UI, SFX mixing, and 4K master capture. - Pattern reuse from proof cuts: Copy proven patterns from the SourceA proof cut (w1 block/tamper sequences, TRUST logo wall beats, outcome VO lines) into new lanes like WitnessBC v5. - Code map for render functions: Reference table linking features to functions like _cinematic_vf(), _mix_vo_sfx(), and _built_on_wall_png() in commercial_short_film_v1.py. - Use Case: Migrating WitnessBC v1 (linear style) to v5 (cinematic style) by diffing polish configs, applying tamper dwell of 9.5s, and re-rendering through Proof Lab. ## Quick Start Enable cinematic_finish and polish.sfx in my beats JSON file and render the v5 film using the Proof Lab capture pipeline.
