Venturi

A Linux-first, performance-oriented video editor written in Rust.

Built for editing, picture and sound, with timelines that travel to and from other NLEs via OpenTimelineIO.

Venturi does little, and does it well. It is an editing-focused NLE: multi-track cutting, the transforms and tools you actually reach for while editing, keyframes on every parameter, transitions, compound clips, ripple delete, and the audio tools to finish the sound in place: a mixer with an effect chain per track and voiceover recording. No node editor, no grading suite, no node-based compositor. Editing is where the time goes, so that is the part that has to be perfect.

NOTE: Venturi is alpha software and is considered unstable, especially the save format. Please use at your own risk.

Features

• Fast playback and scrubbing. Timeline-wide frame cache, optional background proxies, playback up to 8x with pitch-preserved audio.
• Hardware accelerated. Decoding on NVDEC, Vulkan video or VideoToolbox, compositing on the GPU (Vulkan, Metal), export on NVENC, Vulkan or VideoToolbox, with software as the fallback.
• Professional timeline workflow. Track scrubbing with audio, ripple delete, compound clips, copy/paste properties, copy/paste of clips and media between projects and Venturi windows, magnet snapping, clip speed from 1% to 10,000%, unlimited undo with a jumpable history.
• A library shared by all projects. Media and compound clips you reuse everywhere, and property presets (a 2x punch-in with its easing, a drop shadow, a voice level) applied with a drag or a shortcut, timed from the start or the end of any clip.
• Audio, finished in place. A mixer with per-track and master gain, balance, meters and an effect chain: 6-band equalizer and 3-band multiband compressor over the live spectrum, normalization (sample peak, true peak or EBU R128 loudness, per clip or per track), mono, VST3 plugins (macOS and Linux). Voiceover recorded straight onto the timeline.
• Keyframes done right. Every parameter is keyframable: crop, zoom, rotation, position, speed, opacity, audio gain. A dedicated curve editor with custom curves.
• Titles, solid colours, filters, transitions. Applied straight from the timeline, no node graph to wire up.
• Color correction. Shadows, midtones, highlights and offset wheels, auto balance and GPU scopes (waveform, RGB parade, vectorscope, histogram), composed in 16-bit float.
• Interoperability. Timelines move in both directions through OpenTimelineIO, tested with DaVinci Resolve, for 10-bit grading and finishing.
• Drivable by AI agents. A built-in MCP server lets an agent such as Claude Code import, cut, measure audio, look at frames and export, on its own or in the window you are editing. See docs/MCP.md.
• Linux first. Developed and tested on Linux, not ported to it. Also runs on Apple Silicon Macs, and possibly Windows.

Install

On Linux (x86_64 or aarch64), download and run the installer:

curl -fL https://github.com/VenturiVideo/Venturi/releases/latest/download/install.sh -o install.sh
bash install.sh

The downloaded installer stays pinned to that release; use bash install.sh latest to install a newer release later.

The installer requires Bash, curl and tar. It installs the release's AppImage as ~/.local/bin/venturi and adds Venturi to your application menu, without sudo. Pass a release tag such as bash install.sh v0.9.0 to select a version (releases before the installer existed are not supported). Set INSTALL_DIR to choose another binary directory; desktop entries respect XDG_DATA_HOME. Add the binary directory to your PATH to run venturi from the terminal. To uninstall, run bash install.sh --uninstall with the same INSTALL_DIR and XDG_DATA_HOME settings used for installation. This removes the binary, menu entry, icons and MIME registration; your projects are preserved.

AppImages may require FUSE 2; without it, run venturi --appimage-extract-and-run.

For macOS or a manual Linux installation, grab the latest build from the Releases page:

Platform	File	Notes
Linux x86_64 / aarch64	Venturi-<arch>.AppImage	FFmpeg bundled. Needs a Vulkan driver.
macOS (Apple Silicon)	Venturi-arm64.dmg	Ad-hoc signed, see first launch on macOS.

chmod +x Venturi-x86_64.AppImage
./Venturi-x86_64.AppImage

The name

The Venturi effect: when a fluid passes through a constriction, it doesn't slow down, it speeds up. Tight constraints make Venturi faster, so your edits stay fluid even on modest hardware.

Contributing

Issues and pull requests are welcome. For questions, feedback and feature ideas, join the Discord server. Before opening a PR:

cargo fmt
cargo clippy --all-targets -- -D warnings
cargo test --workspace

The CI workflow runs the same three steps on every pull request. Unit tests live in crates/<crate>/src/tests/, not inline, see Where unit tests live. The full conventions (for humans and coding agents alike) are in CLAUDE.md and AGENTS.md; the design is in ARCHITECTURE.md.
