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.

Tips for Better Results

• Always match the total duration of the description to the requested video length (4–15 seconds).
• Keep reference labels consistent (e.g. <Picture 1>, <Video 1>, <Audio 1>) across every section.
• Prefer concrete visual and audio details over abstract words like "cinematic" or "beautiful".
• When using keyframes (I2VA / FL2VA / L2VA), clearly state how the first and/or last frame connects to the timeline.
