I am building a ComfyUI-powered local, open-source video editor (alpha release)

A solo developer has released VLO, an alpha-stage, open-source video editor that runs locally in a Chromium browser. Its standout feature is direct integration with ComfyUI, the popular node-based interface for Stable Diffusion workflows. This means any existing ComfyUI workflow for image or video generation can be applied directly to clips on VLO's timeline, bridging the gap between AI generation and traditional video editing. The editor includes practical tools for AI video work, like aspect ratio fixing to handle model quirks and a timeline selector that picks frame lengths compatible with specific models (e.g., 4n+1 for Warp Fusion).

Built and demoed entirely by the developer, VLO already supports keyframing, spline-based animations, built-in visual effects, and SAM2-powered masking with a point-based editor. The developer acknowledges it's an early "alpha" build, tested primarily on limited hardware, and is actively seeking community help for broader testing on Windows, Mac, and Linux. The immediate goal is to refine the ComfyUI bridge and generation panel, which was developed rapidly. By releasing the project on GitHub now, the creator hopes to attract contributors to help test performance on longer videos and expand its library of built-in workflows.
