Installation

Lumit is free.

Download the build for your platform from lumitlab.com/download to install. If you would prefer to build the project from scratch, find it at github.com/luminalmvm/Lumit.

What you need

A GPU which has support for Vulkan, Direct3D 12, or Metal is required to run Lumit. This can be either a graphics card or integrated graphics.

Windows

Download the .exe installer and run it. It installs for the current user into %LOCALAPPDATA%\Programs\Lumit with no administrator prompt, and carries the C++ runtime Lumit needs.

Lumit is not signed on Windows. SmartScreen therefore shows a blue “Windows protected your PC” panel the first time you run it, and you should choose More info → Run anyway.

Linux

Lumit for Linux is an x86-64 Flatpak. Download the .flatpak and install it:

flatpak install lumit-*.flatpak

Any Linux distribution with Flatpak works. If Flatpak is not set up on your distribution, flathub.org/setup covers it in a couple of commands.

File associations for .lum and .lumfx are not created after installing the flatpak. If you would like to be able to click on project files to open them directly, then clone the repository from GitHub, and run packaging/linux/install.sh.

The .AppImage runs without installing. It needs glibc 2.35 or newer, and uses the system’s own GTK and WebKitGTK:

chmod +x lumit-*.AppImage
./lumit-*.AppImage

macOS

Lumit runs on Macs with Apple silicon and macOS 12 or newer. Download the .dmg installer and run it.

Building from source

Clone the repository and follow the README. The engine is written in Rust and the interface in Flutter.

git clone https://github.com/luminalmvm/Lumit.git

First start

On its first start Lumit opens Set up Lumit. Each choice is applied as it is made, and each is an ordinary row in Settings afterwards.

The Editing style cards set how footage arrives and how the Retime graph reads. See Coming from After Effects, Vegas, Premiere Pro or Resolve.

Card	Sets
After Effects	Footage arrives as a layer, and the Retime graph shows the time value of the source. Use the After Effects shortcuts loads that keymap.
Vegas	Video arrives as a Sequence layer, and the Retime graph shows speed as a percentage. Only change default Retime graph leaves video arriving as a layer. Use the Vegas shortcuts loads that keymap.
Premiere Pro or Resolve	Footage arrives on Sequence layers, in the Cut workspace.

Below the cards are Style, Colour scheme, Toolbar position and Motion, and the tick Check for new versions of Lumit automatically. Skip puts the look back as it was. Continue keeps the choices.

The tour

The guided tour runs once after setup, and again from Help ▸ Lumit tour. Each step dims the window except one part and names it on a card: the Project panel, the Viewer, the tools, the Timeline’s layers, columns and properties, the graph editor, Effects & presets, Effect controls, the effect menus, the workspaces and the node graph.

• Next and Back, or the Right and Left arrow keys, move between steps.
• Skip or Esc ends the tour. The last step’s button is Done.
• A step whose part is not on screen is passed over.
• In an empty, unsaved project the tour builds a composition called Tour and removes it when it ends. It brings forward the panels it needs and puts the window back as it was.

Updating

With Edit ▸ Settings ▸ General ▸ Updates ▸ Automatic updates on, Lumit checks for a new version at launch, at most once a day. Downloading always waits for a click. The latest build is also on the download page.

The Help ▸ Check for updates row and the button beside This version in the same Settings group read what the updater is doing. The line under This version says which version is installed and what the last check found.

Label	Pressing it
Check for updates	Checks now.
Click to update - v{version}	Offers the update.
Downloading update… {n}%	Unavailable until the download ends.
Restart to finish updating	Asks about the restart.

An update goes through these windows in turn:

1. Update to Lumit {version}?, with the file’s name and size. Not now or Download.
2. The download’s progress, with Cancel.
3. Before you update to Lumit {version}, only for a release whose notes have something to read first. Not now keeps the download and leaves the update in the menu. Continue goes on.
4. The restart: Later or Restart now. With unsaved changes the choices are Later, Restart without saving and Save and restart. Later keeps the download, and the next press comes straight back here.

On Windows the installer runs silently and Lumit comes back by itself. An AppImage replaces its own file and comes back by itself. A Flatpak is updated by Flatpak: the last window offers Show the file, and gives the flatpak install --user command for the downloaded bundle.

Lumit keeps the file each update downloads, so the next update downloads only the parts that changed. This applies to the Windows .exe and the macOS .app.zip. Where a patch fails, the whole file is downloaded instead. Every download is checked against Lumit’s signed release manifest, and one that does not match is not installed. A Mac running a build from before 0.8.0 is offered the .dmg.

Nightly builds

Settings ▸ General ▸ Updates ▸ Nightly builds follows nightly builds instead of releases. Turning it on asks first:

Use nightly builds? New features first, less tested. Projects saved in a nightly may not open in the stable version. Keep a copy.

• A nightly is only ever offered nightlies.
• Turning the row off offers the latest stable release, even when it is older than the nightly installed.
• Nightly icon, on a nightly build on Windows and macOS, switches between the nightly’s own icon and the regular one.
• A nightly build shows a Nightly pill on the status line.

Releases are announced on the Lumit releases page, GitHub releases page, and our Discord.
