Audit video and audio files for quality issues including compression artifacts, frame rate inconsistencies, fake HDR, subtitle problems, telecine patterns, and format compatibility using mediainfo, ffmpeg, ffprobe, and mpv; receive detailed diagnostics and encoding recommendations to optimize handling without quality loss.
npx claudepluginhub robbyt/claude-skills --plugin multimediaThis skill should be used when the user asks "what's wrong with this video", "why does this video look bad", "detect video artifacts", "find quality issues", "video has artifacts", "identify compression artifacts", or wants to diagnose specific quality problems in a video file.
This skill should be used when the user asks "what does this mediainfo mean", "explain this video format", "what is BT.709", "what is H.264", "container vs codec", "why is this 10bit", "what does limited range mean", or wants educational explanations of video technical concepts.
This skill should be used when the user asks "check frame rate", "is this CFR or VFR", "video has duplicate frames", "video stutters", "frame rate issues", "why does video judder", or wants to analyze frame rate characteristics and detect timing problems.
This skill should be used when the user asks "is this real HDR", "check HDR metadata", "fake HDR", "is this Dolby Vision legitimate", "HDR vs SDR", "check HDR peak brightness", or wants to verify whether HDR content is genuine or inverse tonemapped from SDR.
This skill should be used when the user asks "compare these videos", "which source is better", "compare blu-ray vs web", "which release should I use", "compare video quality", or needs to evaluate multiple versions of the same content to determine which has better quality.
This skill should be used when the user asks "check subtitles", "audit subs", "subtitle font issues", "ASS vs SRT", "missing fonts", "subtitle timing", or wants to analyze subtitle tracks for issues like missing fonts, timing problems, or format limitations.
This skill should be used when the user asks "is this interlaced", "detect telecine", "video has combing", "should I deinterlace", "3:2 pulldown", "inverse telecine", or sees horizontal lines/combing artifacts in video and wants to understand if the content is truly interlaced or telecined.
This skill should be used when the user asks to "audit this video", "analyze video quality", "check this video file", "is this video good quality", "should I reencode this", "what format is this video", or wants to understand a video file's technical properties and quality before working with it.

/plugin pluginsManage and uninstall pluginsrobbyt-claude-skillsSome plugins require the following tools:
uv - Python package installer and runner (installation guide)jq - JSON processor for parsing tool inputExternal formatters are called directly from your PATH:
ruff - Python formatter (install via uv sync)black - Python formatter (install via uv sync)gofmt - Go formatter (version matches your installed Go)swiftformat - Swift formatter (install via brew install swiftformat)For reproducible formatting, pin tool versions in your project's dependency files (pyproject.toml, go.mod, etc.).
Claude Code plugins can contain scripts that run on your local computer. Only install plugins from sources you trust. Consider enabling the sandbox feature: /sandbox (see sandboxing docs)
