What MiniMax H3 on hevzo.com Can Generate from Text, Images, or Reference Clips

MiniMax H3 on hevzo.com is a browser-based AI video generator that turns text prompts, images, or reference clips into cinematic video with native stereo audio, at 768P or 2K resolution and durations from 4 to 15 seconds. You can use it without installing or configuring anything, and the interface exposes generation modes for single-frame, start-and-end-frame, and reference-based creation. The exact output depends on which input type and mode you choose.

What inputs MiniMax H3 accepts

The model is built around multimodal understanding, so text, images, video, and audio can all feed into one generation process rather than separate tools.

• Text prompts — You describe the scene, characters, actions, and storytelling you want. The prompt field holds up to 5000 characters, which is enough for a detailed shot description rather than a single keyword.
• Images — You can generate from a still image, which anchors the visual style or subject.
• Reference clips — The "Reference" generation mode lets you supply a clip to guide the result, which is useful when you want continuity with existing footage.
• Start and end frames — The "Start & End" mode takes a beginning and ending image so the model fills the motion between them.

Because these inputs share one workflow, you can move from an initial idea to a coherent visual result without stitching together separate production steps.

Output specifications you can select

Before generating, you set the format of the result. The available controls are:

The 16:9 and 9:16 options cover standard landscape and vertical formats, so the same tool fits both widescreen and social-media output. Choosing 2K raises the detail level, while 768P is the lighter option.

What kinds of video it produces

MiniMax H3 is positioned for dynamic scenes, detailed visuals, and smooth storytelling rather than static or purely abstract output. In practice that means:

• Marketing and social content — short clips in the aspect ratio the platform needs.
• Product demonstrations — a subject shown in motion, guided by an image or reference clip.
• Creative projects — scenes built from a text description, with character and action direction coming from the prompt.

Native stereo audio is generated alongside the video, so the result arrives with balanced sound and audio depth rather than a silent track you have to score separately. This matters most for content where sound carries part of the message, such as a product demo with ambient audio or a social clip with a soundtrack.

How to generate a video

1. Choose your input type. Pick Image, Video, or the text-to-video path depending on whether you have a still, a clip, or only a description.
2. Write or supply the prompt. For text-driven generation, describe the scene, subject, and action in the prompt field (up to 5000 characters). For image or reference input, the visual carries the style while the prompt directs motion and story.
3. Set aspect ratio, resolution, and duration. Match the format to where the video will be published.
4. Select a generation mode. Use Single Frame for a one-image start, Start & End to control both ends of the motion, or Reference to follow an existing clip.
5. Generate and review. The interface shows a "Generate 780" action; the resulting clip reflects your chosen resolution, duration, and mode.

Common sticking points

• Duration ceiling. The interface lists 4s through 7s as selectable durations, while the model is described as supporting up to 15s. If you need a longer clip, check whether the duration control expands beyond the listed options before assuming a 15-second output.
• Prompt length is not the same as prompt precision. A 5000-character limit invites long descriptions, but a well-structured prompt that separates scene, character, and action tends to guide the model more reliably than a dense paragraph.
• Reference mode is not a copy tool. Supplying a reference clip guides style and continuity; it does not reproduce the clip frame for frame.
• Audio is generated, not imported. Native stereo audio comes from the model, so plan your sound design around what the generation produces rather than expecting to drop in an existing track.

If your goal is a short, sound-included clip built from a description, a still, or an existing reference, MiniMax H3 on hevzo.com covers that in one browser workflow. Start with the format and mode that match your target platform, and keep the prompt focused on the motion you want rather than restating what the image already shows.
