ffmpeg-skill

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.

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.

FFmpeg is a collection of libraries and command-line tools for processing multimedia content, including audio, video, subtitles, and related metadata. Its libraries provide codec implementations, streaming and container-format handling, filtering through directed graphs, device access, audio mixing and resampling, and image scaling and color conversion. The toolset includes ffmpeg for manipulating, converting, and streaming media, ffplay for playback, and ffprobe for inspecting media content. The codebase is mainly licensed under the LGPL, with optional components under the GPL. The repository is an official mirror of the FFmpeg project's Git repository; the project directs contributors to submit patches through its mailing list rather than GitHub pull requests.

OpenEdit is an open-source, agent-driven video-editing pipeline from VEED. It has no graphical interface or timeline; an agent-agnostic skill and repository guide drive it through coding agents such as Claude Code, Codex, and Gemini. The pipeline can edit, cut, and reframe footage; create burned-in subtitles, motion graphics, charts, and visual elements; assemble slides, websites, stills, or generated media into video; capture web pages; and connect generation services or MCP servers when needed. Source footage is optional, and VEED Fabric can generate footage only with the user's approval. For captioning, the agent transcribes the video, designs the captions, renders the result, opens a video previewer, and accepts follow-up requests such as changing subtitle color, position, or emphasis. Transcription can use VEED, local offline WhisperX, or a user-supplied service; all providers must produce per-word timings, which are stored in a common transcript format. Caption styles are authored in HTML and CSS. The project includes VEED's closed-source but free-to-use HTML renderer, which does not require a headless browser; Chrome can be used as an alternative rendering backend. V1 primarily targets captions, while motion graphics, charts, and brand-book-matched styling are less exercised. OpenEdit supports Apple Silicon Macs and Windows x64 PCs. Intel Macs are unsupported, Linux support is planned, and Windows requires Git, Node, and ffmpeg. It can be installed from the repository or with `npx skills add veedstudio/open-edit`.

A Claude Code skill for converting scripts into MiniMax H3 shot lists and directing character performance. It breaks scenes into shots based on emotional-beat density, using controlled comparisons and documented inferences about MiniMax H3 output; its central rule is to split shots that contain too many facial-expression beats because H3 may otherwise produce a frozen face. The skill also covers dialogue-tag effects on frame allocation, camera placement, observable body actions for silent characters, reference-image use for shapes, edit-based handling of pauses and emotional transitions, PSNR-based verification, dubbing constraints, tail degradation, and a six-step breakdown workflow. It is installed with `npx skills add https://github.com/phileiny/h3-storyboard-skill --skill h3-storyboard` or by copying the skill directory into `.claude/skills/`. The repository distinguishes controlled findings from partly verified and inferred rules, and describes its scope as serialized short-form drama produced with local ComfyUI and MiniMax H3.
