Video Editor Skills for Claude Code

An open-source AI agent skill for Claude Code, Codex, and similar coding agents that produces cinematic product, marketing, launch, and demo videos with Remotion. It provides shot recipe cards, motion previews, a reusable video template, and workflows for storyboarding, real page capture, animation, 2.5D camera moves, sound design, beat-synced cuts, and visual checks. The repository includes native Remotion components driven by normalized progress values, a gallery for browsing motion previews, and an optional JianYing project export that separates shot plates, captions, sound effects, and background music into editable tracks. It can be installed through the skills CLI, by cloning the repository, or by linking it into a Claude Code or Codex skills directory.

ffmpeg-skill is an agent skill that gives Claude Code, Cursor, Codex, and other agents a local video- and audio-editing workflow built on FFmpeg and ffprobe. It uses a probe → edit, preferring stream copying where possible → check → verify process, with typed Python scripts rather than shell strings. Its 21 tools cover cutting, joining, silence removal, duration and aspect-ratio fitting, captions, overlays, graphics, HDR-to-SDR conversion, LUTs, audio cleanup, loudness, synchronization with drift correction, multicamera editing, delivery checks, project rendering, and batch processing. Each tool supports structured results and dry runs, and the machine-readable contract generates an MCP interface whose tool definitions are derived from the scripts. The skill runs locally without cloud services, API keys, or Python dependencies beyond the standard library; it requires FFmpeg 5.0 or later. It is a tool for local, agent-controlled workflows that probe, edit, verify, and render video.

A Claude Code skill for creating motion-design videos in code using HTML, Playwright, ffmpeg, Python, and Chromium. It computes each frame from a deterministic seek(t) function, renders frames with Playwright, blends subframes for motion blur, and encodes the result with ffmpeg. Its motion system includes closed-form springs, log-space camera keyframes, shared-element handoffs, masked word-by-word text, color floods, and ports of selected 21st.dev components. The workflow moves from inputs and a beat map through still-frame approval, full rendering, pop detection, audio generation, and final muxing. Audio processing finds musical drops by band energy, aligns the song to a key visual frame, places sound effects at measured peaks, and applies two-pass loudness normalization. The repository also includes a remake mode for frame-locked recreations with shot analysis, side-by-side verification, and royalty-free replacement audio. The code is MIT-licensed; downloaded third-party media remains under its respective license.

editonny is a free, open-source local video-editing skill for Claude Code and Codex, created and maintained by Matheus Gomes. Users describe an editing result in plain language; the skill inspects footage, selects complete takes, measures cuts against the waveform, assembles a project, adds captions or motion scenes when requested, reviews a representative sample, and exports a checked MP4. Transcription, rendering, OCR caption checks, and media processing run locally, while optional external generators require authorization before costs or media transmission. It preserves original footage and requires confirmation of editing settings before processing. The repository includes a command-line installer, a local guide, bundled motion scenes and clips, project files, verification manifests, and diagnostic and test commands. First-party code and documentation are licensed under the MIT License; third-party assets retain their own licenses.

video-use is an open-source video-editing tool for coding agents such as Claude Code, Codex, Hermes, and Openclaw. It takes raw footage in a folder and produces an edited MP4, with support for removing filler words and dead space, applying FFmpeg color-grading chains, adding short audio fades at cuts, burning customizable subtitles, and generating animation overlays through HyperFrames, Remotion, Manim, or PIL. Its pipeline transcribes each source with ElevenLabs Scribe, packing word-level timestamps, speaker diarization, and audio events into a Markdown view. The agent reasons over that transcript and requests filmstrip, waveform, and word-label composites from timeline_view only at decision points, rather than processing every video frame as visual context. It then creates an edit decision list, renders the result, evaluates the rendered video at every cut boundary for visual jumps, audio pops, and subtitle problems, and can revise and re-render up to three times. The tool uses an approval-oriented workflow in which the agent inventories sources, proposes an editing strategy, waits for confirmation, executes the edit, evaluates it, and persists session memory in project.md. It requires FFmpeg and an ElevenLabs API key; yt-dlp is optional for downloading online sources. Outputs are placed in an edit directory next to the source footage.
