# Video Workbench Case Pattern Library
This directory is the local case-pattern library for Codex execution work in Video Workbench.
It is extracted from old GPT case files only at the level of structure, granularity, page or storyboard method, speaker-note style, visual asset layering, and review dimensions. It is not a prompt library and not a copy of the old GPT knowledge base.
## Source Basis
The first two patterns were localized from:
- `knowledge-vault/prompts/GPT/强哥的策划导演/30_CASE_典型视频分镜案例.md`
- `knowledge-vault/prompts/GPT/强哥的策划导演/31_CASE_典型培训AI_PPT案例.md`
Those source files remain historical GPT assets in Knowledge Vault. Video Workbench uses the extracted patterns below as Codex-side local execution guidance.
## Cases
| case | use when | local output focus |
| --- | --- | --- |
| [science-video-page-style-case.md](science-video-page-style-case.md) | Turning a deep article, model point, or public-facing concern into a PPT-style science video | Shot/page granularity, narration pacing, visual metaphor, review criteria |
| [training-ai-ppt-case.md](training-ai-ppt-case.md) | Turning AI education, method training, product enablement, or workshop content into a teachable slide deck | Teaching unit design, speaker notes, interaction, editable slide structure |
## Local Use
Use these cases after GPT V2 stage 0-5 planning has been accepted into a project `intake/` directory. Codex then converts the accepted planning into:
- `project.md` for project map and current focus;
- `execution-plan.md` for execution strategy, batch, round, and next decision;
- `visual-system/visual-system.md` for visual-system materialization and review;
- `slides/slides.md` and `slides/sNN/` for page or shot execution facts and assets.
## What To Extract
Extract these parts from old or future real cases:
- medium branch and audience;
- logic-to-page or logic-to-shot decomposition;
- page or shot function;
- one-unit-one-purpose granularity;
- editable page text vs visual asset vs narration or speaker notes;
- visual-system anchors and reusable motifs;
- review dimensions and acceptance criteria;
- batch/iteration advice.
## What Not To Inherit
Do not inherit these legacy assumptions:
- GPT outputs final image prompts.
- GPT outputs Codex JSON execution packages.
- GPT specifies local output paths, task lists, or generation parameters.
- the old assumption that every image prompt must forbid readable text.
- old source filenames or schemas become current Video Workbench contracts.
For current Video Workbench, text placement is an execution decision. Body copy is usually rendered in the editable PPT or video page layer; image-generated labels, formulas, diagrams, or text are allowed only when the execution plan and review criteria explicitly require that layer.
## Review Dimensions
When adding a new case pattern, check:
- Does the pattern state which medium branch it serves?
- Does it describe unit granularity without copying a full old case?
- Does it separate source logic, page or shot copy, visual assets, and narration/speaker notes?
- Does it provide review criteria that Codex can apply during small-batch iteration?
- Does it avoid old Prompt, JSON, path, and global text-rendering rules?
