H3 Prompt Writing

Workflow

Identify the input mode: T2VA, I2VA, FL2VA, L2VA, or full-reference Ref2VA.
For base text/keyframe modes, read references/base-en.txt and follow its final prompt structure.
For full-reference mode, read references/ref-en.txt and follow its six-section rewrite format.
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.

ai-video-generation
Generate AI videos on RunComfy via the `runcomfy` CLI — a smart router across the full video-model catalog: HappyHorse 1.0 (Arena #1, native in-pass audio), Wan-AI Wan 2-7 (open weights, audio-driven lip-sync), ByteDance Seedance v2 / 1-5 / 1-0 (multi-modal cinematic), Kling 3.0 / 2-6, Google Veo 3-1, MiniMax Hailuo 2-3, ByteDance Dreamina 3-0. Covers text-to-video (t2v), image-to-video (i2v), and Veo's video-extend endpoint. The skill picks the right model for the user's intent (Arena-#1 quality, multi-shot character identity, in-pass audio, cinematic motion, fastest path, sub-15s clip, longest duration) and ships each model's documented prompting patterns plus the minimal `runcomfy run` invoke. Triggers on "generate video", "make a video", "text to video", "t2v", "image to video", "i2v", "animate", "AI video", "make X move", "video from prompt", "video from image", or any explicit ask to produce a video clip from prompt or still.
