What Is MiniMax H3?
A multimodal video model
MiniMax H3 works with text and visual context. This page focuses on one image plus one motion prompt.
One image sets the opening frame
Your upload establishes the starting composition. Choose a clear subject, useful detail, and a crop that suits the destination.
A prompt directs the change
Explain what moves, what stays stable, how the camera behaves, and what atmosphere supports the shot.
Story321 settings stay simple
This form exposes duration and resolution only. Output framing follows the uploaded image, so prepare the source crop before generating.
Why Use MiniMax H3 for Image to Video?
Start from a visual decision
Use an approved still when the subject, product, setting, color, and composition already matter.
Plan movement before rendering
Give the clip one motion priority: a turn, push-in, fabric movement, reveal, or lighting change.
Match the output to the job
Test one action at 5 seconds and 768P first. Add time or resolution only when the scene needs it.
Review an editable creative brief
For the next version, change one instruction such as camera direction, pace, or mood instead of adding competing details.
How to Create a MiniMax H3 Image-to-Video Clip
- 1
Choose a clear starting image
Upload one image with the subject and crop you want to preserve. Keep important details away from the edges.
- 2
Write one complete motion prompt
Name the subject, action, setting, lighting, and camera behavior. Avoid unrelated cuts or new scenes.
- 3
Set duration and resolution
Choose 5-15 seconds and select 768P, 2K, or 4K. Review higher-resolution output at the target placement.
- 4
Generate, inspect, and refine
Check the subject, motion, and source framing. Adjust one priority at a time in the next prompt.
MiniMax H3 Image-to-Video Use Cases
Product motion concepts
Test a product reveal, material movement, tabletop camera move, or lighting transition. Review labels before publishing.
Social opening ideas
Animate a poster, product image, or character still. Choose the intended vertical, square, or landscape source crop.
Storyboard and pitch scenes
Turn an approved keyframe into motion for a storyboard, presentation, or creative review.
Atmospheric transitions
Create one visual bridge: mist, reflected light, rain on glass, or a shift from daylight to evening.

Frequently Asked Questions
What is MiniMax H3 image to video?
This image-to-video workflow creates a short video from one uploaded image and a written motion prompt. In Story321, the model uses the image as the starting frame, then applies the selected duration and resolution to generate the clip.
What should I include in a MiniMax H3 prompt?
Write one connected shot: subject, movement, setting, lighting, and camera behavior. A useful MiniMax H3 prompt tells the model what should change and what should stay visually important. Add detail only when it affects the actual scene.
Which MiniMax H3 settings are available on Story321?
Choose a 5-15 second duration and 768P, 2K, or 4K output. This MiniMax H3 form accepts one starting image and follows its framing. It does not expose an ending-image field, an aspect-ratio selector, prompt expansion, or a separate audio switch.
Does MiniMax H3 support image-to-video and text-to-video?
MiniMax H3 is a multimodal video model with multiple creation modes. This page is specifically for image-to-video. Use the MiniMax H3 text-to-video page when a written prompt, rather than an uploaded opening image, should define the scene.
How are MiniMax H3 credits calculated?
MiniMax H3 credits are charged per generated second and resolution: 18 credits at 768P, 29 at 2K, and 36 at 4K. Multiply the rate by the selected whole-second duration. A default 5-second 768P generation costs 90 credits.
Can I use MiniMax H3 for a first-and-last-frame video?
Not in this Story321 form. The page supports one starting image only. Prepare the opening composition carefully, describe the intended transition in the prompt, and use the result as a focused single-shot generation.
Does MiniMax H3 add audio in this form?
This Story321 form has no separate audio control. Keep all visual direction in the main prompt and review the generated output before using it in a final edit.
MiniMax H3 Pricing
MiniMax H3 credits are charged per second according to the selected resolution. A 5-second generation at the default 768P resolution costs 90 credits.
