Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00042 | $0.02495 |
| Opus 5 | $0.00021 | $0.01247 |
| Sonnet 5 | $0.00008 | $0.00499 |
| Haiku 4.5 | $0.00004 | $0.00249 |
Grade A, and why
ffmpeg-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 11d 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.

FFmpeg Production
FFmpeg recipes for video post-production. Covers the operations you reach for daily: format conversion, scaling, trimming, concatenation, compression, and AI video post-processing.
For platform-specific export presets (YouTube, TikTok, Instagram, Twitter), see references/platform-presets.md.
Post-Processing Filter Order
Sequence determines correctness, not just quality. This is a physical constraint.
[1] Temporal denoise — remove inter-frame shimmer before any processing
[2] Scale — scale before sharpening avoids halos
[3] Sharpen — recover edge detail lost in generation/upscale
[4] Color grade (LUT) — normalize over-saturated AI palette
[5] Curves/EQ — fine-tune contrast and shadow lift
[6] Film grain — LAST before encode; grain before denoising destroys it
[7] Encode — libx265 -tune grain or AV1 FGS
Violations cause correctness failures: grain before denoising destroys it; interpolation after grain synthesis causes tearing.
Full chain as a single filtergraph:
ffmpeg -i input.mp4 \
-vf "hqdn3d=2:2:3:3,\
scale=1920:1080:flags=lanczos,\
unsharp=5:5:0.8:5:5:0.4,\
lut3d=grade.cube,\
curves=r='0/0 0.5/0.52 1/1':b='0/0.03 1/0.97',\
noise=alls=6:allf=t+u" \
-c:v libx265 -crf 18 -preset slow -tune grain \
-c:a copy output.mp4
Hald CLUT Color Grading
Preferred for iterative grading: export a Hald CLUT, grade in Photoshop/GIMP, re-import. No re-encoding between iterations.
ffmpeg -i input.mp4 -i hald_clut_graded.png \
-filter_complex "[0:v][1:v] haldclut" \
-c:v libx265 -crf 18 output.mp4
Format Conversion
Codec Selection
| Target | Codec | When to use |
|---|---|---|
| Web/streaming | libx264 | Universal compatibility |
| Archive/master | libx265 | ~40% smaller at same quality |
| Modern distribution | libsvtav1 | Best compression, slower encode |
| Browser embed | libvpx-vp9 | WebM container, good compression |
What ships with it
1 file 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.
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.

ffmpeg-production is a skill published in the GitHub repository Galbaz1/video-research-mcp (23 stars, last pushed 1mo ago), licensed MIT. It adds 42 tokens to every session and 2,495 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

gemini-skill
A skill that uses the Gemini website, Google's AI assistant, for conversations and image generation. It defines how the assistant should choose tools and handle long-running requests.
video-perception
Use when the user mentions a video file (.mp4, .mov, .avi, .mkv, .webm), a YouTube URL, asks to watch/analyze/review a video, or references video content in conversation.
b123d-repair
Use this skill when validate() or the export() gate reports FAIL on a shape — an imported STEP that arrives broken, or a solid your own construction damaged — and the goal is a watertight, manifold, BRepCheck-valid solid that passes the export gate without changing the geometry beyond the defect itself.
image-generation
Optimizes image generation prompts using Subject-Context-Style structure. Use this skill when generating images, creating illustrations, photos, visual assets, editing images, or crafting prompts for any image generation model.
