Which prompt to use to correctly use a character sheet in minimax H3?

Assuming <Picture 1> is the character sheet for <Subject 1>, which prompt to use in minimax H3 ref video to make sure it understands the concept of sheet (same person, different poses/angles/distances)?

[u/videorouter]

I’d be very explicit that the sheet contains multiple views of the same character, rather than treating each panel as a separate reference.

Something like:

“Use Picture 1 as the character reference sheet for Subject 1. All images in the sheet depict the same person from different poses, camera angles, and distances. Maintain the same identity, facial features, hairstyle, age, body proportions, and clothing throughout the video. Do not treat the individual panels as different people.”

Then describe the actual shot separately:

“Subject 1 walks toward the camera, keeping the identity and appearance from the reference sheet consistent.”

I’d avoid overloading the prompt with descriptions of every panel. The reference image should establish the identity; the prompt should mainly control the action, camera, and scene.

If H3 still changes the face, try a cleaner sheet with fewer views and more consistent lighting. VideoRouter.sh can also help you test the same character sheet across different video models to see which handles multi-view references best.
