# H3 Prompt Writing

> Write MiniMax H3 video generation prompts for T2VA, I2VA, FL2VA, L2VA, and Ref2VA. Use when rewriting multimodal requests into H3 prompt structures, composing integrated_multimodal_description, overall_soundscape, and non_diegetic_music, aligning keyframes, or defining reference labels for images, videos, and audio.

# H3 Prompt Writing

## Workflow

1. Identify the input mode: T2VA, I2VA, FL2VA, L2VA, or full-reference Ref2VA.
2. For base text/keyframe modes, read `references/base-en.txt` and follow its final prompt structure.
3. For full-reference mode, read `references/ref-en.txt` and follow its six-section rewrite format.
4. Preserve the exact field names, section order, labels, and timing notation from the selected guide.

## Base Modes

- T2VA: build the full audiovisual timeline from text.
- I2VA: start from the first frame and develop forward from it.
- FL2VA: describe the continuous path between the first and last frames.
- L2VA: infer a plausible opening and converge to the supplied last frame.

Use `integrated_multimodal_description`, `overall_soundscape`, and `non_diegetic_music` in the order shown in `references/base-en.txt`.

## Full-Reference Mode

Ref2VA rewrites use `subject_definitions`, `summary`, `retention_analysis`, `detailed_description`, `overall_soundscape`, and `non_diegetic_music` in that order. Reference labels stay consistent across all sections.

Read `references/ref-en.txt` for label rules, retention analysis, and complete examples.

## Output Rules

- Write rewrite sections in English; preserve dialogue, lyrics, and visible scene text in their original language.
- Describe each shot by composition, subjects, environment, actions, camera, sound, and the exact point where referenced content appears.
- Avoid plot summaries, unresolved reference labels, and timing that does not match the requested duration.
