Create a polished, brand-matched promo video for the current repo. Use when the user asks for a promo/launch/marketing/trailer/social video, app teaser, or "show off this project as a video". Extracts the repo's brand (colours, fonts, logo, name, feature copy), scaffolds a config-driven Remotion + ffmpeg pipeline, and renders multiple aspect ratios (16:9, 9:16, 1:1, 4:5) plus poster frames, with a live in-browser editor for fine-tuning.
Professional ffmpeg usage for encoding, transcoding, filtering, and producing social-platform video and audio deliverables, with version and security discipline baked in. Use whenever a task involves ffmpeg or ffprobe directly, converting or compressing video/audio, changing codecs/containers/resolution/ frame rate/bitrate, trimming, concatenating, overlaying watermarks or subtitles, normalising loudness, extracting frames or poster images, mixing background music, or exporting web-safe MP4/WebM for YouTube, X, LinkedIn, TikTok, Reels, Shorts or Instagram. Also load this when another pipeline (for example a Remotion render) needs ffmpeg to finish, package, or re-encode its output.
Build and render videos programmatically with Remotion, the React video framework. Load this skill when scaffolding a Remotion project, writing compositions, animating with the frame clock (useCurrentFrame, interpolate, spring), wiring typed input props with a Zod schema, loading fonts and assets, running Remotion Studio, or rendering to MP4/WebM/stills via the CLI or @remotion/lambda. It also covers two things that are easy to get wrong: pinning the latest secure version, and Remotion's company-licence requirement (free for individuals and small teams, paid above a defined team size). Use it standalone or as the engine behind the sibling promo-video skill.
