MiniMax H3 Max Prompt Tips: Better Image-to-Video Results

If a portrait suddenly changes its face or a product starts bending, the problem is often the prompt. A good MiniMax H3 Max prompt gives the model one clear action, one camera decision, and a simple ending.

Start with the image

Treat the uploaded image as the opening frame. Ask for something that could naturally happen next: a person glancing toward a window, steam rising from coffee, or a slow camera move around a stationary product.

Use this simple structure:

Subject action + camera movement + details to preserve.

The woman slowly looks toward the window. The camera stays still.
Keep her appearance, clothing, and the room consistent with the
uploaded image.

This works well for MiniMax AI image to video because it extends the starting frame instead of asking the model to rebuild the whole scene.

Keep one main action

Short clips become difficult to control when the prompt asks for too much. Start with one action, then add one change at a time.

The man slowly raises the cup toward his lips, then pauses.
His other hand stays on the table. The camera remains still.

If the face drifts, reduce the head movement. If the product bends, remove object rotation and let the camera provide the motion.

Three prompts to try

Portrait

The subject forms a slight, closed-mouth smile, with a small natural
movement of the shoulders. The camera stays still. Keep the face,
hairstyle, clothing, and background consistent with the uploaded
portrait. End with the subject holding the expression.

Product

The bottle stays upright and stationary on the surface. The camera
slowly moves closer, keeping it centered. Soft reflections shift
across the glass. Preserve the bottle's shape, cap, colors, and label
placement. End on a steady closer view.

Coffee scene

Thin wisps of steam rise from the coffee, curl gently, and disperse.
The cup and table remain still. The camera holds the original framing,
with steady window light and a softly blurred background.

Replace vague adjectives with visible instructions

“Cinematic,” “premium,” and “high quality” can suggest a style, but they do not explain what should happen in the frame. Try instructions you can review: “the camera moves closer,” “the reflection travels across the glass,” or “the subject turns slightly, then holds the pose.”

Review the middle of the generated clip as well as the first and last frames. Change one instruction between attempts so you can tell what improved the result.

Try it in I2video

Upload an image to I2video, choose a supported duration, and start with one action and one camera instruction. Generate a first version, then refine the part that needs work. A clear, manageable shot is usually a better starting point than a prompt packed with competing directions.
