What Natron is
Natron is a free, open-source application for visual-effects compositing in digital post-production, available for Linux, macOS, and Windows. Its node-based workflow lets users build, group, and save custom tools and presets, and its interface includes more than 100 nodes. Listed compositing tools cover chroma keying, matte refinement, rotoscoping, rotopaint, tracking, and stabilization. Natron supports the OpenFX plugin standard and community-made plugins, along with OpenImageIO and OpenColorIO and 32-bit floating-point linear color processing. Python scripting can be used for expressions, user-defined parameters, scripts, callbacks, and GUI extensions. Rendering options include headless command-line rendering and integration with render farms for distributed work. Natron has no 3D workspace, but can be used with Blender and supports CHAN camera-tracking files. Minimum requirements include 3 GB RAM, 5 GB free disk space, a 1280×1024 display, and OpenGL 2.0 for hardware-accelerated GPU rendering. The project lists version 2.5.0, released November 25, 2022.
