Score, narrate, caption, and render your film in one window
RxFilmStudio is a native macOS app that consolidates film post-production tasks — scoring, narration, captioning, stills, and rendering — into a single window, with an AI agent that proposes edits for review before they're applied. Version 1.9.0 is a 41 MB download for Apple Silicon Macs.
Generate music cues with Lyria, with sections like Intro, Build, Chorus, and Outro, keeping every take in one reel.
Voice narration tuned line by line, with multiple speakers (e.g., Narrator, Guest 01, Guest 02) on the timeline.
Transcribe, translate, and retime captions, with export to VTT or SRT.
Create stills and reference art without leaving the app.
A real editing timeline combining video, voice, and score, rendering at 4K (3840×2160) at 60 fps directly from the app.
Ask the agent for a change — e.g., a fade-in on the wide shot, retimed captions, or a swapped chorus take — and review every proposed edit as a diff before it lands.
Everything — music, narration, captions, stills, and the timeline — is organized around a reel at 3840×2160 and 60 fps inside one window.
Instead of hand-editing everything, you ask the agent for changes; it proposes file-level edits (e.g., changes to Scene01.tsx or captions.vtt) that you review and approve before they're applied.
Free. The download is listed as "macOS · Apple Silicon · Free" at version 1.9.0.
