MiniMax H3 Reference to Video AI Generator

What Is MiniMax H3 Reference to Video?

MiniMax H3 Reference to Video is a multimodal video-generation model available on Story321. It accepts reference image URLs, reference video URLs, and reference audio URLs with a written prompt, then produces a 5–15 second video. MiniMax H3 Reference to Video needs at least one visual reference, while audio remains an optional supporting input.

MiniMax H3 Reference to Video Features

• Multimodal direction in one request

  MiniMax H3 Reference to Video can receive up to nine images, three short video references, and three audio references. Use only the inputs that clarify the final shot rather than treating every upload as required.

• Long prompt capacity

  The MiniMax H3 Reference to Video prompt accepts 1–50,000 characters. A short, connected shot brief is often easier to evaluate than a long list of unrelated scenes.

• 5–15 second output

  Choose any whole-second MiniMax H3 Reference to Video duration from 5 through 15 seconds. Start with five seconds for motion tests, then increase duration after the direction is working.

• 768P, 2K, and 4K choices

  Use 768P for an economical review, 2K for the default balanced output, or 4K when the final use needs more image detail. The form calculates the MiniMax H3 Reference to Video credits from this choice.

• Adaptive and fixed framing

  MiniMax H3 Reference to Video supports adaptive, 21:9, 16:9, 4:3, 1:1, 3:4, and 9:16 aspect ratios. Select the placement early so composition follows the intended format.

• Supported payload only

  Story321 uploads local inputs first, then sends only prompt, duration, resolution, aspect ratio, reference URL arrays, prompt expansion, and enabled safety checking to the MiniMax H3 Reference to Video endpoint.

When MiniMax H3 Reference to Video Is a Good Fit

• You need consistency from source assets

  Use MiniMax H3 Reference to Video when a recognizable product, character treatment, set, art direction, or campaign asset should influence the clip more directly than a text prompt alone.

• You have a motion or sound cue

  A short reference video can communicate movement, pace, or camera energy, while a short audio reference can contribute a sound-world cue. Keep both clips within their 15-second combined limits.

• You want a clear review process

  Hold the core MiniMax H3 Reference to Video assets steady and edit one prompt clause, output setting, or supporting reference between versions. This makes creative reviews more specific.

• You are making short-form campaign tests

  Generate a compact vertical, square, landscape, or ultra-wide proof of concept before expanding the idea in a traditional edit or a wider production process.

How to Use MiniMax H3 Reference to Video

1. 1

   Add visual references first

   Upload at least one image or video to MiniMax H3 Reference to Video. Images can anchor appearance and art direction; videos can demonstrate a motion or camera intent.

2. 2

   Add optional audio intentionally

   Add up to three audio references only when they clarify rhythm or ambience. Each clip must be 2–15 seconds and all audio references together must be 15 seconds or less.

3. 3

   Write a connected brief

   For MiniMax H3 Reference to Video, state subject, action, location, lighting, camera behavior, speed, and the elements that must remain recognizable. Prompt expansion is enabled by default.

4. 4

   Choose output settings

   Choose a 5–15 second duration, 768P, 2K, or 4K resolution, and an aspect ratio. The default MiniMax H3 Reference to Video setup is 5 seconds, 2K, and adaptive framing.

5. 5

   Review one shot at a time

   Check identity, motion continuity, camera framing, and the relationship between visual and audio direction. Improve the next version with one targeted change instead of replacing the complete brief.

MiniMax H3 Reference to Video Use Cases
