RxFilm Studio: an AI agent that scores, narrates, captions, and renders product videos in one macOS app

Show HN: RxFilm Studio–Create and edit your product videos with AI agent

RxFilm Studio is a native macOS app that packs the entire product-video pipeline into one window. An AI agent acts as the "director" — it generates music cues via Lyria, multi-speaker narration, auto-captions with translation (exportable as VTT/SRT), still images, and final 4K 60fps renders via Remotion. Every edit is proposed for review before it lands. Version 1.9.0 is free and Apple Silicon only. The post doesn't specify which model Lyria is or how many languages the narration supports.
