What OpenVideo is

OpenVideo is open-source video generation that runs MiniMax H3 locally on an NVIDIA GPU. Its command-line workflow can install the system, download model weights, check status, and generate clips from prompts. Supported modes include text-to-video, image-to-video, first-frame, and first-last-frame generation. The active backend offers native stereo audio and shots up to 15 seconds, while the listed maximum resolution is 720p and the maximum video length is 0.25. ComfyUI serves as the local render engine. OpenVideo is available for Linux, macOS, Windows, and the web, and a packaged skill supports Claude Code, Codex, Cursor, and OpenCode. Local use requires no account or API key. Requirements include Linux or macOS, an NVIDIA GPU, Python 3.10 or later, ffmpeg, and about 60 GB of free disk. Windows GPU use requires WSL2. The Apache 2.0 open-core project has no API currently; desktop, HTTP API, and MCP surfaces are planned.

Who it suits

OpenVideo suits technically capable users with an NVIDIA GPU who want local, account-free generation. It also fits developers using its supported agent hosts.

Verdict

OpenVideo offers local generation with several input modes and no account requirement. Its hardware, storage, operating-system, and unfinished-surface requirements make it a better fit for technical users than casual browser-only creators.
