Open Source Project #242: HyperFrames — Write HTML, Render Video, a Deterministic Video Framework Built for AI Agents
HeyGen's open-source HTML-to-video framework: describe a video with HTML, data attributes, and seekable animation (GSAP and friends); headless Chrome captures frame by frame and FFmpeg encodes, so the same input always yields the same video. Ships 21 agent skills so Claude Code, Codex, and Cursor can produce video from a single prompt. Apache-2.0, 68k+ Stars, used in production at HeyGen.
Open Source Project #190: claude-video — Give Claude Eyes to Watch Videos, One Command to Analyze YouTube/Loom/Local Files, Subtitle-First Zero-Download, Scene-Aware Frame Dedup, Auto Token Budget
Brad Bonanno's Claude Code skill plugin that gives Claude the ability to analyze any video via the /watch command. Seven-step pipeline: yt-dlp download → ffmpeg frame extraction → Whisper transcription → Claude context injection. Subtitle-first optimization (use existing subtitles, skip download entirely), 16×16 thumbnail MAD algorithm for frame deduplication, automatic frame budget scaling by video duration. Four detail modes: transcript/efficient/balanced/token-burner. Works with Claude Code, Codex, Cursor, Copilot, Gemini CLI, and 50+ other agent hosts. 15.2k Stars, MIT.
