Text-to-Video or Image-to-Video?
Use Text-to-Video when the scene can be invented. Use First/Last-Frame Image-to-Video when the opening composition, subject, product, or interface must begin or end from a supplied image.
Open answerMode selectionFirst frame or first-and-last frame?
Use First/Last-Frame Image-to-Video with one image to animate away from a controlled start. Use two images when both endpoint compositions matter and H3 must create the transition.
Open answerMode selectionWhen should you use Reference Generation?
Use Reference Generation when several images, videos, or audio clips need distinct roles such as identity, wardrobe, setting, motion, or sound. It is unnecessary for a scene text alone can define.
Open answerConsistencyHow to keep a character consistent in MiniMax H3
Consistency improves when one clear image owns identity, other references have narrower roles, and the prompt avoids changing wardrobe, age, lighting, and camera distance at the same time.
Open answerConsistencyHow to reduce product shape drift
Product shape drift usually starts when several references compete for ownership or when transformation, camera motion, reflections, and typography are tested at once. Establish a baseline with one clean product reference, one simple camera move, and explicit constraints for silhouette, proportions, materials, labels, and moving parts before adding creative motion.
Open answerCameraHow to write camera movement in an H3 prompt
Describe camera type, direction, amplitude, speed, and timing. "Slow push toward the subject from waist-up to close-up between 2 and 6 seconds" is more executable than "cinematic camera".
