Create a 15-second movie trailer with MiniMax H3

A MiniMax H3 movie trailer has at most 15 seconds to establish a world, create tension, and land on a memorable ending. That constraint favors a compact idea over a summary of an entire film. One character objective, one escalation, and one title beat can produce a reviewable trailer structure.

H3 generates native stereo audio, so the sound plan can carry continuity across fast visual changes.

Write a three-beat trailer

Use the opening seconds for orientation: who, where, and what feels wrong or urgent. The middle introduces a change, threat, discovery, or action. The ending holds a face, object, line, or title long enough to register.

If the trailer contains cuts, describe the order and purpose of each shot. Do not overload every beat with a new character and location. Repeated visual elements, such as one color, symbol, or prop, help the sequence feel related.

Assign references to story functions

Use images for characters, locations, props, or title design. A video reference can define camera energy or a performance beat. Audio may establish a voice, rhythm, or sonic motif, but it must accompany visual media.

Within Omni Reference, up to 12 mixed files are allowed. That is a capacity limit, not a target. Include only references that resolve a visible decision.

Make the soundtrack structural

Plan ambience under the opening, a rising or interrupted music element in the middle, and one controlled impact at the end. Place dialogue where it remains intelligible. If a title appears, reduce competing motion and sound long enough for it to read.

Review character identity, geography, cut timing, exact words, and the final hold. Watch once without audio to test visual clarity, then listen without the picture to test the sound arc.
