WeftCut
What WeftCut is
WeftCut is a free, open-source desktop video editor for Linux, macOS, and Windows. MCP agents can edit its timeline through a bundled bridge or HTTP-direct connection, including clients such as Claude Desktop, Cursor, and Codex. Tools cover timeline changes, motion, effects, text, Motifs, audio, analysis, project structure, and history. Agent actions appear in a live change feed, can be grouped into checkpoints, undone, or checked with dry_run before application. The standalone editor includes an A/B-roll timeline, keyframes, effect chains, chroma key, captions, audio mixing, silence removal, and export. It exports H.264, HEVC, AV1 up to 10-bit, ProRes, and DNxHR for a full timeline or selected range. Motifs are reusable animated overlays for titles, 2D drawings, and 3D scenes. Editing, export, and several analysis functions run locally and can work offline. Cloud transcription, scene description, or agents require network access.
