MiniMax H3 AI Video Generator

Nothing to install. MiniMax's own weight repository is roughly 498.5 GB and even the trimmed ComfyUI bundle is 42.47 GB. Here the download is 0 GB: open the page and the generator is already running. No GPU to rent, no API key to manage.

No editor afterwards. The dialogue, effects and music are already mixed into the MP4 you download, so a finished clip is a finished clip — there is no second pass in a timeline to align audio to picture.

Nothing to pay before you know whether it works. The first clip needs no account, no email and no card; you clear one bot check and it runs.

No guessing at the specs. Every number on the site links to the primary source with the date it was last checked, which is why our figures disagree with the pages that copied each other.

Failed runs do not cost you. Credits return automatically, and a failed anonymous attempt does not consume that day's clip.

| **Short-form social video** | 9:16 · 7–10s | Ambience is already mixed in, so the clip posts straight from the download folder. |

| **Product ads with sound** | 9:16 or 1:1 · 5–8s | One product photo goes in, a turntable shot comes out, and the sound effect lands on the logo reveal. |

| **Dialogue scenes** | 16:9 · 8–12s | `(S1)` and `(S2)` tag the speakers, and lip movement lands on the syllable rather than near it. |

| **ASMR and ambience** | 16:9 · 6–8s | No dialogue at all — just material sounds and the sound of the room. |

| **Character-consistent series** | 9:16 · 8s | Reference images hold the same face and the same wardrobe while the camera changes. |

| **Remixing footage you already have** | 16:9 · 6s | Keeps the original camera move and pacing, swaps only the visual style. |

| **Anime and multi-shot tests** | any ratio, up to 15s | Several shots inside 15 seconds, with camera-movement vocabulary you can steer. |

| **Reverse-engineering a prompt** | prompt tool, no render | Feed in a clip you admire, get a structured prompt back, edit it, then generate. |
