Why use it?
It brings separate rendered media together and applies common finishing work in one workflow.

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-editing 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 today.

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.

How it starts

The opening of the file, as written. The whole thing — 108 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Video editing

Vendor-neutral craft for local post-production on finished media. Works with any clips, stills, VO, or beds you already have — from any source.

This skill is not generative video editing. It does not write motion prompts or call video generation APIs. Produce or collect media first; assemble and polish here.

Install

Skill Description Install
video-editing Use when assembling or polishing already-rendered clips with ffmpeg — concat, crossfades, burned captions and subtitles, text/logo overlays, before/after sliders, background music beds, platform export — or when composing a multi-layer HTML combination video with Hyperframes. Not for AI video generation, prompt craft, or model-based video edits. npx skills add PrunaAI/pruna-skills@video-editing -y

When to use

  • Stitch multiple rendered clips (hard cut or crossfade)
  • Burn in phrase captions — word-accent promo, simple phrase (landscape explainers), or line-block — see captions.md
  • Add title cards, lower-thirds, or logo watermarks
  • Build before/after or side-by-side comparison clips
  • Mix an instrumental bed under dialogue or VO (~10–20% under speech for explainers; taste varies)
  • Export for social aspect ratios (9:16, 1:1, 16:9) with loudness normalization
  • Compose a multi-act narrated showcase (hook, context, reel, close) via HyperFrames or ffmpeg — narrated-showcase.md
  • Compose a combination video with UI chrome, chat mocks, or multi-panel layouts via Hyperframes (optional — see combination-hyperframes.md)

Works with

Any finished MP4/MOV/WebM plus local ffmpeg / ffprobe. Caption alignment often uses Replicate whisperx (or any timed transcript you already have). Beds and VO may come from any TTS or music tool. Upload helpers in sibling skills are optional, not required.

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.
