LaunchVideo

HyperFrames is an open-source framework for turning HTML, CSS, media, and seekable animations into deterministic MP4 videos. It can be used locally through a CLI, by AI coding agents through skills, or as a rendering core for hosted authoring workflows. Compositions are defined as HTML with data attributes for timing, tracks, media, and sub-compositions. The renderer seeks each frame in headless Chrome, uses animation adapters such as GSAP, CSS, Lottie, Three.js, Anime.js, or WAAPI, and encodes the result with FFmpeg; its toolchain includes preview, linting, inspection, local rendering, browser-based editing, reusable catalog components, and AWS Lambda rendering. The project requires Node.js 22 or newer and FFmpeg, does not require React or a build step, and is licensed under Apache 2.0. Its agent skills support workflows including product videos, explainers, pull-request videos, captions, motion graphics, slideshows, music-driven videos, and general compositions.

Null Motion is a local browser-based motion-design preview and export tool that presents a finished advertisement alongside the black-and-white HyperFrames drafts used to plan it. It includes an earlier launch editor and ships with example references and authored draft scenes. The project uses FFmpeg scene detection to divide reference videos into sections while preserving their cuts. Each section is represented as a 640×360 HTML scene on a paused GSAP timeline, with beats such as text, logos, phones, windows, chats, cards, lists, charts, and clouds. During playback, the active draft is driven by the film’s clock and stays synchronized frame by frame with the reference video. For export, a hidden video plays at half speed; requestVideoFrameCallback captures decoded frames, the drafts are rendered at each frame’s timestamp, WebCodecs encodes the video, and mp4-muxer produces an MP4 with copied reference audio. The tool runs with Node.js 22 or newer and requires Chrome or Edge for WebCodecs export. Reference media remains local, and the repository states that the drafts are authored rather than AI-generated. No project-wide open-source license has been selected.

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.

procedural-film is an agent skill that turns a topic into a 30-second vertical film. It uses vanilla JavaScript to draw every pixel on a canvas and Web Audio to synthesize every sound, producing a self-contained HTML player and MP4 exports without media assets. An agent plans the film, dispatches parallel subagents to write shot scene files, and runs critic reviews across the shots. The repository includes a shot-type index, scene and music guides, planning templates, a rendering engine, and a monarch-butterfly reference film. It requires Node.js 20 or newer, ffmpeg, and Chromium for Playwright; the project is licensed under MIT.

product-film is a Claude Code skill for creating product films in Remotion, including landing-page loops, launch videos, promos, and demo reels from a product's real components, design tokens, logo, and stated claims. It first inspects the product's design rules, tokens, components, live site, logo, and claims, then interviews the user about the film's duration, placement, music, features, and visual ingredients. It records the resulting brand kit in videos/BRAND.md, creates a beat sheet, analyzes the music's beat grid, builds time-based Remotion scenes, and supports review through style frames, stills, contact sheets, and a draft render. The final workflow renders a 240 fps master with motion blur and can produce a muted loop, a music version, a WebM file, and a poster; verification scripts decode the outputs and check colors, duration, and loop continuity. It runs in a local Claude Code toolchain rather than the Claude chat apps, requires Node.js, Bun, and uv, and is distributed under the MIT license for its own text and code.
