name: paper-collage-explainer-generator

description: Translate narration, ideas, or knowledge points into editorial halftone paper-collage metaphors, still prompts, storyboards, or stop-motion clips. Use for photographic cutout collage and tactile assembly, distinct from paper-puppet dioramas or generic cartoons.
|
|
metadata:
|
|
compatibility: File-based workflow with sibling h3-prompt-writing; media creation uses available image/video tools and an editor when needed.

# Paper Collage Explainer Generator
|
|
|
|
Read the [portable workflow](../h3-prompt-writing/references/portable-workflow.md)
|
|
and [collage design](references/collage-design.md) when constructing scenes.
|
|
Honor prompt-only and asset-only requests as well as finished video requests.
|
|
|
|
## Meaning and media policy
|
|
|
|
Extract each source line's meaning, emotion, action verb, visual metaphor, and
|
|
three to six readable object groups. Preserve the user's topic and wording as
|
|
context; do not put narration on screen merely because it is available.
|
|
|
|
Default to tactile paper SFX, with no BGM, voiceover, or subtitles unless requested.
|
|
An explainer does not inherently require speech. Existing user requests for those
|
|
layers already establish the choice; do not ask again. A short 16:9 clip of roughly
|
|
four seconds is a useful default for one assembly beat, subject to backend limits.
|
|
|
|
## Plan the image and motion together
|
|
|
|
Create a concise plan of metaphor, palette, object groups, assembly order, duration,
|
|
and sound cues. For a series, keep paper texture, halftone treatment, keylines,
|
|
shadows, and rhythmic language consistent; vary the metaphor and color field only
|
|
where the meaning benefits. A user's no-text or no-music requirement applies to
|
|
every downstream asset, prompt, clip, and edit.
|
|
|
|
Design each still as the completed final composition. Use black-and-white
|
|
photographic halftone cutouts, selective colored cardstock, warm cream keylines,
|
|
subtle fiber/torn edges, and soft physical layer shadows on a bold color field.
|
|
Keep layered depth and negative space; avoid excessive age, dirt, wrinkles, or
|
|
automatic brown/kraft backgrounds. Exact editable layers require a compositing
|
|
workflow, not a claim that a generated raster video is a layered project.
|
|
|
|
Generate final-composition stills when requested/needed and inspect them. Follow
|
|
any requested approval gate; otherwise continue within the authorized workflow.
|
|
|
|
## Animate the assembly
|
|
|
|
Start from a clean paper field matching the planned final color. Base pieces enter,
|
|
then the main metaphor, then supporting objects. Each piece slides or pops in,
|
|
bounces slightly, presses flat, pauses, and locks. End with a brief hold on the
|
|
completed composition. Use stop-motion assembly rather than global fades, smooth
|
|
digital drifting, fast spinning, or liquid morphs unless explicitly requested.
|
|
|
|
Use the supplied final still as a last-frame anchor only when the backend supports
|
|
it. Otherwise identify it honestly as composition/style guidance; do not describe
|
|
a reference image as a guaranteed final-frame constraint. Compile the actual H3
|
|
mode with the sibling guide and bind only real inputs.
|
|
|
|
Map short paper slides, pops, taps, rustles, and snaps to motion. Preserve those
|
|
SFX during assembly. When the user adds music or narration later, mix with the
|
|
useful SFX unless they request full replacement.
|
|
|
|
## Review and deliver
|
|
|
|
Check the metaphor without relying on text, object count/readability, matching
|
|
opening color, visible piece-by-piece construction, final-frame resemblance,
|
|
controlled paper texture, and no unwanted UI/letters/music/voiceover. If the
|
|
assembly is weak, simplify the groups and make their arrival order concrete.
|
|
|
|
For multiple clips, preserve the planned order and SFX. Deliver prompts, current
|
|
stills, and actual clips/assembly as requested. Explain any missing generation
|
|
capability or remaining drift; keep raw output separate from edited fixes.
