What is whiteboard-video-workflow?

A collection of workflow steps for turning subtitles into whiteboard-video storyboards, source images, and merged video segments. It supports debugging individual stages of that process.

Use it for subtitle-to-storyboard work, image-prompt generation, provider-specific image creation, aspect-ratio checks, and segment merging.

It lets you inspect or rerun one stage when a full automatic whiteboard-video pipeline is not enough.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00056	$0.00403
Opus 5.5	$0.00022	$0.00161
Sonnet 5.5	$0.00011	$0.00081
Haiku 4.5	$0.00006	$0.00040

Security

Grade A, and why

whiteboard-video-workflow scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

The scan reads SKILL.md. This mod also ships 5 executable files (scripts/banana_prompt_template.py, scripts/check_env.py, scripts/generate-image.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Whiteboard Video Workflow

Prefer skills/auto-whiteboard-video for normal end-to-end requests. Use this Skill only for stage-level diagnostics or custom SRT workflows.

Environment

Provider configuration lives in the ignored .env beside this file. Create it through scripts/configure_keys.py; do not edit or print secrets during routine runs.

Supported image providers are apimart_image2, kie_image2, t8_image2, and macode_image2.

Components

scripts/generate-storyboard.py: create storyboard.json from subtitles and scene groups.
scripts/workflow_helper.py: create output directories, build prompts, and merge segments.
scripts/generate-image.py: generate source images with the configured provider.
scripts/banana_prompt_template.py: enforce the locked whiteboard drawing style.
references/storyboard-parser.md: storyboard rules.
references/image-generator.md: image-provider workflow.

Invariants

Keep scene, image, duration, and video arrays in identical order.
Treat durations as integer milliseconds across the whole pipeline.
Request near-16:9 source images and reject clear 3:2, square, and portrait responses.
Normalize accepted images to the flat #F6F1E3 background before animation.
Use abstract faceless circular-headed people; text must remain sparse and secondary to drawings.
Preserve cached outputs unless a fingerprint changes or a force flag is explicitly requested.

Stage-Level Validation

Run the repository doctor before troubleshooting. After a custom stage run, verify the expected file count and inspect any JSON manifest before continuing to the next stage.

Files

What ships with it

8 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
