What MiniMax H3 Max is good at
MiniMax H3 Max gives you control over the starting material and the short scene you want to make.
Picture and sound together

Use MiniMax H3 Max at 480P to check the idea, then select 768P when the shot needs more detail. Each render is a separate paid request.

Give MiniMax H3 Max opening and ending images, then describe the movement between them.
Bring your own material
Guide MiniMax H3 Max with images, video or audio relevant to your subject, movement or sound.
Control prompt expansion
