Inline Studio

Inline Studio is a free, open-source desktop application designed for AI filmmakers to construct films shot by shot using a node-based canvas. The platform enables users to build, iterate, and manage entire film projects visually, allowing each shot to be created as a separate workflow that can be layered and connected within a single narrative pipeline. This approach supports frame-by-frame iteration and versioning, so every stage and take is preserved on the canvas, providing a comprehensive view of the production process.

The tool offers flexibility in generating media by allowing users to utilize either their own ComfyUI instance or hosted AI models through the Fal API. With ComfyUI, users can run the workflow locally (with GPU support) or deploy it on a cloud GPU, connecting Inline Studio to any reachable ComfyUI server. For those without access to a GPU or who prefer not to manage their own workflows, Inline Studio supports direct integration with hosted models via Fal, enabling model selection and generation without setup or hardware requirements. Users maintain control over their Fal API keys, pay Fal directly for usage, and receive price estimates before running models. The platform supports mixing outputs from both ComfyUI and Fal-hosted models within the same film project.

Editing features are integrated directly into the node canvas, where users can assemble sequences, trim video and audio clips, and manage timelines as nodes within the larger workflow. The "Video Director" node combines rendered frames into a single video cut, supports layering of audio tracks with per-input and per-layer volume controls, and provides in-node preview and high-resolution export. A dedicated trim node allows precise control over segment selection for both video and audio, which can then be routed through the editing pipeline.

Inline Studio is available for macOS (both Apple Silicon and Intel), Windows, and Linux platforms. It is distributed under the MIT license, with no cost to download or use. The application does not bundle ComfyUI, requiring users to run their own instance if desired, but provides guidance for cloud deployment. The tool is positioned as a solution for organizing, iterating, and producing AI-generated films without the need to switch between multiple applications.
