This repo contains 10 individual skills — each has its own dedicated page.
> Declarative animations for React. Springs, gestures, layout animations, and page transitions. GPU-accelerated, production-ready.
> Create animated logos, icons, and micro-interactions as lightweight Lottie JSON files. No After Effects needed — build animations entirely in code.
> A TypeScript library using generators to program animations with a real-time editor. Ideal for explainer videos, code walkthroughs, and educational content.
> Add animated subtitles and captions to Remotion videos from .SRT files. TikTok-style word-by-word highlights, karaoke effects, and more.
> Create videos programmatically using React components. The most mature framework for code-driven video production.
> Copy-paste video components for Remotion. Intros, text effects, transitions, and full scene templates. Like shadcn/ui but for video.
Extract actionable intelligence from video content across YouTube, Vimeo, and company websites. Video reveals what text sources cannot: facility scale, team composition, product demonstrations, signage, event attendance, and operational reality.
Optimize and embed an existing video as a fast, crisp, autoplaying hero/background/loop on a website. Use when adding or replacing a video on a marketing site and it is too heavy, will not autoplay (especially on mobile/Safari), shows a codec error, or looks soft — to transcode it to web-safe H.264 with the right pixel format, faststart, retina-aware sizing, and a poster frame, then embed and verify it actually plays. This is optimization + embedding of footage you already have, not creating/animating a video (for that use remotion/moviepy/motion-canvas). Use when the user says "add this video to the site", "the hero video is too big / won't play / isn't crisp", "replace the homepage video", or "make this loop on the landing page".
Full conversion audit for any homepage or landing page. Use when someone asks to "review my homepage," "audit my landing page," "why isn't my page converting," "check my website," or wants feedback on their marketing page. Requires URL or screenshot before proceeding.
Automatically fetch YouTube video transcripts, generate structured summaries, and send full transcripts to messaging platforms. Detects YouTube URLs and provides metadata, key insights, and downloadable transcripts.
Extract frames or short clips from videos using ffmpeg.
Summarize or transcribe URLs, YouTube/videos, podcasts, articles, transcripts, PDFs, and local files.
Use when testing, fixing, or extending the OpenClaw Control UI GUI with Vitest + Playwright end-to-end checks, mocked Gateway WebSocket flows, mocked dashboard runs, screenshots/videos, or agent-verifiable browser proof.
Obra superpowers agent skills.
See, Understand, Act on video and audio. See- ingest from local files, URLs, RTSP/live feeds, or live record desktop; return realtime context and playable stream links. Understand- extract frames, build visual/semantic/temporal indexes, and search moments with timestamps and auto-clips. Act- transcode and normalize (codec, fps, resolution, aspect ratio), perform timeline edits (subtitles, text/image overlays, branding, audio overlays, dubbing, translation), generate media assets (image, audio...
End-to-end marketing campaign planning and execution. Covers audience research, positioning, campaign angle definition, landing page copy, email sequences, social posts, ad copy, short-form video scripts, and content calendars. Use as the orchestration layer for multi-channel product launches. Use when planning or executing a multi-channel product launch, or producing landing page, email, social, or ad copy.
