Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# FFmpeg Media — Edição Mecânica de Vídeo e Áudio Esta skill executa uma edição, não decide uma. Corta, junta, mede, sincroniza, exporta e verifica arquivos de mídia — decisões estéticas (o que é "interessante" num highlight, se uma grade parece "cinematográfica", composição de thumbnail) ficam fora de escopo e voltam pro humano ou pra skill de criação correspondente. ## Governanca Global Esta skill segue `GLOBAL.md`, `policies/execution.md`, `policies/tool-safety.md`, `policies/verification-before-completion.md`, `policies/self-correcting-sensors.md` e `policies/anti-rationalization.md`. **Fronteira mecânico vs. subjetivo — o princípio central desta skill:** aplicar uma LUT nomeada, cortar em coordenadas exatas, medir loudness em LUFS são operações mecânicas, dentro de escopo. Decidir "essa cor combina com a marca", "esse trecho é o melhor momento do vídeo" ou "isso parece profissional" são julgamentos que pedem contexto humano — a skill relata a medição (waveform, LUFS, duração de cena) e devolve a decisão para quem pediu, nunca decide sozinha e apresenta como fato. ## Quando Usar - cortar, juntar, ou re-sequenciar clipes de vídeo já existentes …

How to install
mdr add felvieira/claude-skills-fv/ffmpeg-media@sha256:b610c86edee179d2The line at the top of this page pins the label git:20261030.813a629, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
