Show HN: SixSevenStudio – open-source Video Editor For Sora (github.com)

SixSevenStudio is an open-source native macOS app that streamlines generating and editing AI videos powered by Sora. It bundles an AI storyboard assistant (via an AI SDK) with iterative generation and a built-in video editor (trimming, stitching, transitions), letting creators go from idea to final cut in one place. The app is privacy- and cost-conscious: it uses a “bring your own OpenAI API key” model and stores all videos locally on your filesystem, while ffmpeg sidecar binaries handle the video processing. For developers and power users, SixSevenStudio is a Tauri + npm project you run locally (install ffmpeg with the included script, npm install, then npm run tauri dev/build). It currently targets Apple Silicon Macs. The setup and open-source nature make it easy to inspect or extend—useful for workflows that need local storage, reproducibility, or integration with custom tooling. The main caveats are platform limitation (macOS/Apple Silicon) and dependency on Sora/OpenAI for generation, but the architecture gives good privacy, cost-control, and extensibility advantages for AI/ML practitioners experimenting with video generation pipelines.
