MotionForge — 3D Marvel Character Shorts
Cinematic 3D Shorts Director is an end-to-end production skill for creating polished, reference-driven 3D CGI short-form videos. Turn a simple idea, story concept, script, or character reference into a structured production workflow designed for vertical short-form content. The skill can help you: • Develop visual comedy and short cinematic story concepts • Structure multi-segment stories with strong hooks, escalation, and payoffs • Create storyboard and key-image plans • Generate storyboard images when requested • Preserve character identity from uploaded reference images • Maintain environment, scale, prop, costume, armor, and damage continuity • Generate videos segment-by-segment instead of forcing an entire story into one generation • Apply believable gravity, mass, collisions, breakage, accumulation, and structural physics • Build expressive visual storytelling that can work with little or no dialogue • Perform post-generation QC without automatically wasting generations on retries • Create English and Spanish YouTube metadata packages, including titles, descriptions, focused hashtags, and SEO keywords REFERENCE-DRIVEN WORKFLOW Uploaded character images are treated as authoritative identity references. The Director works to preserve faces, proportions, costumes, armor, colors, materials, accessories, silhouettes, and relative character scale throughout production. PHYSICS & CONTINUITY Physical causality is a core part of the workflow. Falling objects accelerate, impacts create consequences, debris persists, materials accumulate, structures fracture after impact, and visible damage such as dust, scratches, scuffs, and dents can persist between shots. VISUAL STORYTELLING The Director supports visual comedy, character challenges, escalating disasters, reversals, fake victories, shared problems, slapstick situations, cinematic mini-stories, and other short-form storytelling structures. PRODUCTION CONTROL You stay in control of the production process. By default, the Director works one production stage or segment at a time, performs QC, reports the result, and waits for approval before continuing. It does not automatically regenerate failed outputs or assemble clips unless explicitly requested. DEFAULT STYLE Premium stylized 3D CGI, cinematic lighting, expressive animation, polished materials, readable action, strong visual composition, and exaggerated but internally consistent cartoon physics. Ideal for creators building character-driven YouTube Shorts, vertical animated comedy, visual challenges, cinematic mini-stories, and recurring 3D animation series.

# Cinematic 3D Shorts Director ## When to use - User wants a premium stylized 3D CGI short-form comedy video (9:16, ~10s per segment) from an idea, one-liner, script, or character reference images. - User wants a multi-segment story (2–5+ segments) produced segment-by-segment. - User wants storyboards / key images / character sheets / environment references for such a video. - User wants only a single production stage (plan the story / create storyboard / generate the images / generate Segment N / generate only the video prompts / generate the metadata package). - User wants to revise one segment or one stage. ## Core principles - Reference-driven: user-uploaded character reference images are AUTHORITATIVE identity references. Preserve face, head/body proportions, costume, armor, colors, materials, accessories, silhouette, and relative character scale. Do not redesign referenced characters unless explicitly asked. Assign Picture 1 = Character A, Picture 2 = Character B, Picture 3 = environment, etc. Reference identity must persist between segments. - Default visual language: premium stylized 3D CGI, high-end theatrical animated-feature quality — smooth stylized geometry, polished materials, cinematic lighting, expressive facial/body animation, readable silhouettes, strong visual storytelling, colorful but believable environments, exaggerated but internally consistent cartoon physics. Avoid unless requested: live-action photorealism, gritty realism, voxel/Minecraft/Roblox geometry, block characters, pixel art, cheap mobile-game look. - Default format: 9:16 vertical, ~10s per segment. A story may have 2–5+ segments as requested; each works as part of ONE continuous story. - Physical causality and continuity are the most important features. Read `references/physics-continuity.md` before writing any video prompt. - Comedy should work without dialogue (facial expressions, pauses, reactions, body language, anticipation, reversals, visual punchlines). Read `references/story-engines.md` when planning a story. - The user normally assembles the final video manually. mix_clips is DISABLED by default — do not call it unless the user explicitly asks to stitch/mix. ## Generation authority (mandatory) - Every generation request authorizes EXACTLY ONE requested generation call (image or video). After that one call, generation authority expires. - After generation you may inspect, verify, QC, and report. You may NOT automatically regenerate, retry, repair, improve, extend, replace, create a v2/alternate/fallback, or generate the next segment. - QC failure is NOT generation permission. Only the user can authorize another generation. - Default workflow: generate ONE requested segment → QC once → report → STOP. Wait for explicit user instruction before the next segment. - Anti-loop: do not repeatedly re-read skill/reference documentation. Read each reference file at most once per user turn, then proceed directly to generation or report a real technical blocker. Never enter "let me check the skill again" loops. ## Core workflow 1. Clarify the request: story idea, characters (with reference images if any), number of segments, and which production stage is wanted. 2. If reference images are supplied, recognize each with `recognize_image` and lock identity traits (medium, colors, costume, proportions, scale). Keep them authoritative across all segments. 3. Plan the story: choose a story engine, define the central situation, hook, escalation, pause, and payoff. Read `references/story-engines.md`. 4. If the user requests storyboards / key images / character sheets / environment refs, generate them with `generate_image` (see `references/image-workflow.md`). Treat them as authoritative staging references for later video generation. 5. Generate each requested segment with `generate_video` using `model='ref2v'` (reference-to-video) when reference images exist, passing the reference images in `input_urls`. Follow the six-section prompt format in `refere
