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 | $0.00268 | $0.07224 |
| Opus 5.5 | $0.00107 | $0.02890 |
| Sonnet 5.5 | $0.00054 | $0.01445 |
| Haiku 4.5 | $0.00027 | $0.00722 |
Grade A, and why
embedded-captions 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.
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.
This is a copy
92% identical to embedded-captions — 94 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 287 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Embedded Captions
One catalog, picked up front (CATALOG.md — 17 identities; the three engines behind it are backend detail). Standard (default) builds a clean verbatim rail (lower-third subtitle carrying most text) + an embed climax composited into the scene behind the subject at the peak. Cinematic is pure embed — no rail, every caption composited behind the subject (hero typography, accumulation, occlusion as the effect). Theme is a complete themed constitution — body paradigm × hero setpiece × front fx × plate reaction, composed from registries (themes/README.md): ordnance terminal neonsign stardust stomp. Most explainer / voiceover is Standard; embed is the scarce, earned peak — embedding every word is the common mistake; Theme is for VFX-grade asks ("炸", "特效", "像 AE 做的").
Operational flow (TL;DR)
The craft prose below is long; the pipeline itself is short — and everything deterministic is computed or compiled, never hand-written:
- Decision gate (refuse bad clips) → pick ONE identity from CATALOG.md (17 identities; engine/compiler derived by lookup — never surface a mode/category question)
hyperframes init(skip it if the project dir already exists with the video inside —matte.cjs/transcribe.cjsadopt any video in the dir as source.mp4) →bash scripts/prepare.sh <project>(matte ∥ transcribe ∥ audio-envelope in parallel, then safe-zones v2 with scene palette/optics/lighting — one command, nothing forgotten)- author a small JSON of creative choices (read
safe-zones.jsonfirst): Cinematic →plan.json→fill-timings.cjs→fit-fonts.cjs→make-composition.cjs; Theme →theme.json→make-theme.cjs(rail/panel/poem/takeover paradigms;anchoris the quiet rail default) - Visual QA:
node scripts/preview-frames.cjs <project>→ faithful composite previews in ~2s/frame (no render). Check § Visual QA before paying for a render. render-and-composite.sh→ gates (timing / occlusion+hero / overflow / hand-off) →final.mp4

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.

embedded-captions is a skill published in the GitHub repository maiscafe/video_motion (2 stars, last pushed 4mo ago), licensed MIT. It adds 268 tokens to every session and 7,224 once invoked, about $0.0011 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 92% identical to embedded-captions, differing in 94 lines, and is treated as a copy.
