RenderStack is the production pipeline behind Lone Stack Media: write the story, decompose it into scenes and shots, lock in characters and looks, render every take through the AI video provider that fits, then assemble the cut with captions and export. Identity continuity, cost tracking, and a local Asset Library are built in. Windows and macOS. Bring your own AI keys; your data stays on your machine.

Story Builder, AI decomposer, character portraits, scene look packs, render orchestration, editorial, assembly, captions, and exports — all in one .NET 10 MAUI app. No stitching tools together with shell scripts.
Every character has a portrait reference. Every scene has a look pack that locks lighting, palette, and mood. Render takes inherit both, so a person stays the same person and a scene stays the same scene from shot one to shot ninety.
Bring your own keys for Replicate, Anthropic, OpenAI, and other providers. RenderStack picks the cheapest model that meets the shot's capability requirements, tracks per-shot cost against your project budget, and warns before each render burst.
Project state, generated frames, render takes, and license info all live on your machine in a SQLite database and a local asset directory. The bundled MCP server is stdio-only over localhost. No cloud lock-in.
A bundled MCP server (and a standalone CLI) lets Claude Code or any MCP-aware agent drive the pipeline headless — decompose a script, kick off renders, fetch assemblies — without opening the desktop app.
Cost budgeting, retry-with-cheaper-model routing, durable media copies (the local file is the source of truth, not a 24-hour Replicate URL), and a project-bundle export so you can move a film between machines.
Write or paste a script, then use the built-in outline editor to structure it as scenes, beats, and dialogue. Revision history keeps every draft; one revision can be marked Final so the decomposer always works from the version you mean.
Break a script into scenes, shots, characters, and scene-look packs in a single pass. Each shot lands with a canonical creative spec — required capabilities, duration, aspect ratio — that the render orchestrator uses to pick the right provider per shot.
Generate identity-locked portrait references for every character the decomposer found. Edit the description, regenerate variants, and pick the keeper. The chosen portrait becomes the seed reference every shot inherits.
For each scene, build a scene-look pack of reference frames that lock lighting, palette, and mood. Renders pull both the character portrait AND the look pack, so the same conversation in the same diner looks the same across shots.
One-click scene render or per-shot render. The orchestrator routes each shot to the cheapest video model that meets its requirements (Seedance, etc.), tracks live progress per shot, persists outputs locally the moment they're delivered, and reports total spend at the end.
Browse every take across every shot in one timeline view. Compare takes side by side, refine prompts and re-render selected shots, and lock the picks you want in the cut.
Build a scene assembly from selected takes — transitions, music track, titles. Outputs are real concatenated cuts written to disk, ready to drop into a longer edit or hand off.
Generate burn-in or sidecar (SRT/VTT) captions for any assembly. Styled overlay options included.
Export assemblies to delivery formats — MP4 profiles, social ratios, ProRes intermediate. Or export the whole project as a portable bundle (.zip with schema-v2 JSON + every local media file) for transfer between machines.
A unified per-project view of every portrait, scene look, take output, and assembly the project has generated. Filter by kind, open, copy URL, or delete. The library is the durable archive — Replicate URLs expire; the local copy is permanent.
A bundled MCP server (and standalone CLI) exposes the entire pipeline as tools. Drive RenderStack from Claude Code, Cursor, or any MCP-aware agent — decompose, render, assemble, export — without ever opening the desktop app.
Attach external reference images — actor lookbooks, mood boards, location plates — to characters, scenes, or specific shots to steer generation beyond what a portrait or look pack captures.
Indie and Pro start with a 7-day free trial — no card up front, no surprise charges. Bring your own AI keys so you pay providers (Replicate, Anthropic, etc.) only for what you generate.
RenderStack runs locally on Windows and macOS. Free to download — upgrade in-app whenever you're ready to render.
