Concat: A free, open-source, cross-platform video editor with local editing and scripting.

What problem it solves

Concat provides a video editor that runs locally, with no watermark, account, subscription, or upload. It supports graphical editing as well as scripting and AI-agent workflows through a JSON-RPC API and MCP server.

Key features

  • Local editing and AI tools — The editor processes footage locally and includes offline-capable tools for captions, text-to-speech, voice cloning, and background removal.

    Source: README

  • Timeline editing and animation — Multi-track timelines support cutting, trimming, merging, speed changes, overlays, picture-in-picture, and keyframe animation.

    Source: README

  • Effects, titles and audio — Users can work with effects, filters, transitions, styled titles, and voice-cleanup tools in the editor.

    Source: README

  • Scriptable video workflows — A built-in MCP server lets AI agents edit video, while JSON-RPC and gRPC APIs support scripts and services.

    Source: README, docs

  • Cross-platform native application — Concat supports macOS, Windows, Linux, and Android, using a native Rust engine and a GPU compositor.

Quick start

Copied verbatim from the project's README.

cd src
cargo run -p concat          # the editor window
cargo build --profile app -p concat   # the shipping binary (fat LTO, stripped)
cargo test                            # run the test suite
cargo fmt --check && cargo clippy --all-targets -- -D warnings   # what CI checks

Who it may suit

This may suit people who want local, account-free video editing across desktop and Android, as well as developers who need to automate edits through MCP, JSON-RPC, or gRPC.

Topics to discuss

  • Which local AI-assisted editing workflows should the project prioritize next?

  • How should transitions, effects, and sound effects behave when used as timeline layers?

  • What automation and agent integration examples would be most useful for contributors to build?
