H3 prompts: plan shots, dialogue and sound — MiniMax H3 tutorial
Choose the generation mode, understand an official prompt example, and check the alignment of shots, dialogue and sound.
Audience: H3 beginners who have chosen a runtime and want to describe scenes, action, camera and sound clearly.
Hardware: No local GPU is needed to read the guide. Rendering needs an existing local or cloud H3 setup.
Prerequisites
- Decide between text, boundary frames and multimodal references
- Prepare the intended action, dialogue and sound
Steps
- Choose by input: use the base guide for T2VA and boundary frames, and the reference guide for Ref2VA. Do not mechanically mix the structures.
- Open a complete example and identify integrated_multimodal_description, overall_soundscape and non_diegetic_music.
- Check subject action, camera and cut timing in shot order. Each cut should introduce a clear new view and actions must fit the clip.
- Use the official speaker and language format for dialogue. Keep ambience and score in their own sections and check for unintended sound sources.
- Save the complete original example as a reference and edit only what you need. Review action, dialogue and sound after generation, then address one issue at a time.
Caveats
- T2VA / FL2VA and Ref2VA use different reference syntax; use the matching official guide.
- Read complete original prompts at the linked source. These summaries are not verbatim prompts or guarantees of identical output.

Start with complete official examples and understand each field. Explicit shots, dialogue and sound give a more useful starting point than a string of style words.
The official guides are free to read; generation tests use your platform or hardware.
Links lead to the original workflows, models or examples. Supply your own reference assets where needed. This generation workflow has not been independently run by this site.

Troubleshooting
Invented reference assets
Audit every Picture, Video and Audio label and keep only supplied inputs. Do not ask an assistant to guess unseen assets.
Dialogue does not match the shot
Recheck speaker tags, language and shot timing against the official example, and shorten dialogue that does not fit.
