IV Studio is a free desktop app that makes MiniMax H3 short films on your own ComfyUI
IV Studio by Infinite Variance is a free MIT-licensed desktop app for short films with MiniMax H3 on your own ComfyUI. A six-step wizard goes from idea to script, cast, storyboard, filmed shots and a finished cut, with recurring actors, voices, music and a Premiere-style editor.
What it does
Projects walk idea → script → cast and places → animatic storyboard → filming → finished film, keeping faces and rooms consistent. Shots can hunt quick previews then finish at 1–2 MP with upscale options; Create also makes stills with Flux, Krea, Moss, Qwen and others. Characters can be H3 LoRAs with trigger words; voices run locally with VoxCPM2 and Whisper; music uses MiniMax Music 3 or ACE-Step. The editor has multi-track timeline, markers and MP4 export. Optional RunPod or Modal cloud GPUs and a local MCP server with 147 tools.
Worth knowing
v0.3.2 (4 Nov 2026) adds macOS 12+ builds for Apple Silicon and Intel alongside Windows and Linux AppImage. MiniMax H3 itself is under a community licence that excludes the EU, UK, South Korea and the US. Mac builds are not Apple Developer ID signed yet, so first launch needs Open Anyway.
