Hailuo AI changed under most people’s feet this summer. On July 31, 2026, MiniMax launched H3<\/a>, a single model that reads text, images, video, and audio together. It returns up to 15 seconds of 2K video with stereo sound built in. The app sells it as Hailuo 3.0.<\/p>\n\n\n\n

Plenty of the advice that ranks for Hailuo AI was written for the older Hailuo 2.3, though. It tells you to stack quality tags, add negative prompts, and plan around 6-second clips. H3 works differently, and some of those habits now make your footage look worse.<\/p>\n\n\n\n

Below are 6 steps for making realistic ad footage in Hailuo AI, built on the published prompt rules for H3.<\/p>\n\n\n\n

<\/span>What changed in Hailuo AI with H3<\/span><\/h2>\n\n\n\n

First, the names, because they get tangled. MiniMax is the company. Hailuo AI<\/a> is its video app, on the web and on mobile. H3 is the model inside it, and you’ll see it called MiniMax H3, Hailuo 3.0, or Hailuo 3 depending on who’s writing.<\/p>\n\n\n\n

Here’s what the switch means in practice, based on specs reported as of October 2026:<\/p>\n\n\n\n

<\/th>Hailuo 2.3 (now legacy)<\/th>MiniMax H3<\/th><\/tr><\/thead>
Clip length<\/td>6 seconds (10 on higher plans)<\/td>4 to 15 seconds<\/td><\/tr>
Resolution<\/td>768p or 1080p<\/td>768p, or 2K through a regenerate step<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

H3 also adds two things that change how you work: stereo sound made in the same pass as the picture, and a reference mode that takes up to 9 images, 3 videos, and 3 audio clips at once. The big shift is that H3 reads your prompt like a brief. You describe how the pieces relate, and the model works out the rest. That’s why a pile of adjectives does less than it used to, and a clear plan does more.<\/p>\n\n\n\n

<\/span>Step 1: Pick the mode that fits the shot<\/span><\/h2>\n\n\n\n

Hailuo AI gives you three ways in, and the right one depends on what has to stay true on screen.<\/p>\n\n\n\n

Use text only for loose shots where nobody will check the details: a street at dusk, steam off a coffee cup, waves on rocks. Use a start frame (and an optional end frame) when a specific thing must look right from the first moment, like your actual product. This is the Hailuo AI image to video route, and it’s the safest choice for product ads, because the model starts from a real photo instead of inventing your packaging.<\/p>\n\n\n\n

Use reference mode when you need something carried across the clip, which is most UGC-style ads<\/a> with a presenter: a face, a voice, a camera move, or a product seen from several angles. In the app, the prompt box takes up to 12 reference files.<\/p>\n\n\n\n

Pick the aspect ratio before you generate, too. H3 supports vertical, square, and widescreen formats, and cropping a finished clip later can cut off the framing that made it look real. For a start frame, use a sharp, evenly lit photo shot at that same ratio. If the ad is headed for Reels, check this guide to Instagram Reel length<\/a> before you plan the shots.<\/p>\n\n\n\n

A simple rule: the more your sale depends on a detail, the more that detail should come from a real file rather than a sentence.<\/p>\n\n\n\n

<\/span>Step 2: Write the prompt as a timed shot list<\/span><\/h2>\n\n\n\n

MiniMax publishes an official H3 prompt guide, and ComfyUI’s documentation summarizes it alongside its own tips<\/a>. Together they ask for a specific order: describe the overall scene first, then break it into numbered shots, with camera and sound in the same block.<\/p>\n\n\n\n

Each later shot opens with a single cut time, such as “At 00:04.000, the camera cuts to…” You start a new shot when the subject, place, viewpoint, or time changes. A small reframe stays inside the same shot.<\/p>\n\n\n\n
