MiniMax Hailuo 02 Video

MiniMax Hailuo is the text-to-video workhorse of the closed video lineup, and this built-in node is how you use it without leaving ComfyUI. Its reputation among people who actually generate is "solid, middle-of-the-road, occasionally great" - it won't dethrone Veo on wild camera moves, but it's dependable, and Hailuo-02 handles a plain descriptive prompt better than most of the field. If the phrase "a person walks through a rain-soaked alley at dusk" needs to become footage, this node will do it.

Like every node in the built-in partner/video category, it's an API node: ships with ComfyUI core, no local models, calls MiniMax's API through Comfy Org's backend, and bills your Comfy account in credits. The task shows as "Queued / Processing" in the UI while Hailuo renders, then the finished clip arrives as a VIDEO output.

The inputs that matter

• prompt_text - the whole game. Hailuo is a text-to-video model, so this carries the scene, subject, and motion. Keep it descriptive and concrete.
• duration - 6 or 10 seconds, default 6. Here's the trap: at 1080p, Hailuo-02 only allows 6 seconds. Pick 10 at 1080P and the node rejects the combination with a clear error. 10-second clips are a 768p thing.
• resolution - 768P (1366x768) or 1080P (1920x1080). Default 768P, and for Hailuo that's the sensible value - it's where the model is fastest and most stable.
• first_frame_image - optional. Plug in an image and this becomes an image-to-video node instead; otherwise it's pure text-to-video.
• prompt_optimizer (default on) - MiniMax rewrites your prompt server-side for better results. Leave it on unless you've already hand-tuned your prompt and want it passed through verbatim.
• seed - the usual family behavior: a re-run toggle, non-deterministic results either way.

Output is a single VIDEO.

Where people get burned

• The 1080p duration lock. This is the one that surprises everyone. You will set 1080P, slide duration to 10, and get a validation error. The tooltip on resolution spells out the dimensions, and the model simply doesn't do 10s at full HD.
• It's closed and it's billed. Hailuo sits in the "all closed source" column of every community roundup ("Vidu, Kling, Hailuo, all closed source"). No weights, no local version, per-clip pricing that climbs with resolution and duration. The badge is honest about it.
• Prompt optimizer can fight you. If you're prompting in a style you've already tuned, the automatic rewrite can drift it. Toggle it off for prompt fidelity; leave it on for convenience.

For a "prompt in, clip out, minimal fuss" node, this is one of the friendliest in the whole partner category. Just remember: 10 seconds lives at 768p, and every render is a line item.
