Motion graphics that play back at speed.
A native compositing and motion-graphics editor built first for the editors After Effects forgot. GPU-first, open source, and built to stay responsive in projects with thousands of layers.
Windows, Linux and macOS · GPLv3 · free forever
Why it exists
The gaming-edit scene runs on a stack that fights back.
Preview lag, RAM exhaustion, render-time blackmail on blur and retiming, and projects that grow until the app is barely usable — plus an external tool chain bolted around the gaps. Lumit is one application that covers it: After Effects' compositing model, Vegas' retiming soul, GPU-first throughout.
Playback is the product
A GPU-resident pipeline with content-hash caching and adaptive degradation. The UI thread never renders a frame, so the app answers input in every state — including mid-export.
Retiming you don't fight
Ramp-and-cut retiming with the feel editors go back to Vegas for, solved on exact rational time so a speed ramp lands on the frame you asked for.
Everything After Effects has, eventually
Its own version of each AE feature, an AE project importer, and OFX plugin hosting so the tools you already own come with you.
Open source, GPLv3
The whole engine and interface, in the open. No subscription, no per-seat licence, and no plugin tax on the basics.
Roadmap
Where it goes next.
Lumit is in public beta. This is the honest state of things — what works today, what is being built, and what is further out.
