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.

Security

Grade A, and why

video-post-production 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 10d 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.

Video Post-Production Guide

Rules and FFmpeg patterns for finishing videos: audio mastering, captions, color, and platform-specific export.

Audio Rules

Volume Levels (dB)

Track Level Notes
Voiceover -12 to -10 dB Primary audio, clear and upfront
Music (under VO) -32 to -24 dB Background, should not compete
Music (solo, no VO) -16 to -12 dB Can be louder when alone
Sound effects -18 to -14 dB Accent, not distraction
Silence floor -60 dB True silence feels unnatural, keep room tone

Music Selection by BPM

Mood BPM Range Use Case
Calm, reflective 60-80 Luxury brands, testimonials
Confident, steady 80-100 Corporate, explainers
Moderate energy 100-120 Product demos, features
Energetic 120-140 Launch videos, social ads
High energy 140+ Montage, fast-cut sequences

Rule: Match music tempo to edit pace. Cut on beats for professional feel.

Audio Mastering Chain (FFmpeg)

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.
