Natron
Free open-source node-graph video compositor comparable to After Effects, Nuke and Fusion.
GPL-2.0 compositing with OpenFX and rotoscoping
Natron is a free, open-source video compositor under GPLv2, similar in function to After Effects, Nuke and Blackmagic Fusion. It suits compositors who prefer node graphs.
What it is
The README lists a 32-bit floating-point linear colour pipeline with OpenColorIO, many formats through OpenImageIO and FFmpeg, OpenFX plug-ins, rotoscoping, tracking, a curve editor and dope sheet, Python scripting and headless rendering.
Who it's for
It suits visual-effects artists who composite footage in nodes. It does not suit anyone who wants a layer timeline with text animation templates, because Natron is node-based.

Our honest verdict
What's great
- Renders run in a separate process so a crash does not take down the main app.
- Standalone builds for Linux, macOS and Windows plus a Flatpak.
- Multi-layer EXR compositing and multi-view workflow.
- Software rendering is possible without a GPU.
Where it falls short
- Hardware acceleration needs an OpenGL 2.0 GPU; otherwise set software rendering.
- The stable branch named in the README is RB-2.5 and GitHub lists a 2024 release as the latest.
- Node-based work has a learning curve if you come from layer timelines.
