Natron is an open source professional-quality video compositing software.
We are looking for funding from partners (studios, software companies…) to support the development of Natron. Please email contact@natron.fr if you can help us keep Natron alive.
Commercial support and development of custom features is also available, backed up by Inria (http://inria.fr). Please contact our sales department at sales@natron.fr for pricing and information.
Release notes:
– OpenGL rendering is enabled by default for interactive editing in plugins that support it (but still disabled for background rendering)
– Roto & RotoPaint: ellipses and circles are more accurate #1524
– When a plugin is not available with the right major version, use the smallest major version above for better compatibility (before that change, the highest major version was returned)
– Natron can now be launched in 32-bits mode on macOS
– Documentation is now licensed under CC BY-SA 4.0, and external contributions are welcome
– Organize nodes documentation
– New project formats: HD_720, UHD_4K, 2K_DCP, 4K_DCP
Plugins:
– The plugins that were made available as beta features in the 2.1 releases are now considered stable:
– DenoiseSharpen: new wavelet-based denoising plugin
– EdgeBlur: Blur the image where there are edges in the alpha/matte channel.
– EdgeDetect: Perform edge detection by computing the image gradient magnitude.
– EdgeExtend: Fill a matte (i.e. a non-opaque color image with an alpha channel) by extending the edges of the matte.
– ErodeBlur: Erode or dilate a mask by smoothing.
– HueCorrect: Apply hue-dependent color adjustments using lookup curves.
– HueKeyer: Compute a key depending on hue value.
– KeyMix: Copies A to B only where Mask is non-zero.
– Log2Lin: Convert from/to the logarithmic space used by Cineon files.
– PIK: A per-pixel color difference keyer that uses a mix operation instead of a max operation to combine the non-backing screen channels.
– PIKColor: Generate a clean plate from each frame for keying with PIK.
– PLogLin: Convert between linear and log representations using the Josh Pines log conversion.
– Quantize: Reduce the number of color levels with posterization or dithering
– SeExprSimple: new simple expression plugin with one expression per channel
– Sharpen & Soften: new plugins.
– SlitScan: Per-pixel retiming.
– SeNoise: fix bugs in the Transform parameters #1527
– PIKColor: do not expand region of definition
– Shadertoy: support iDate, add presets, fix CPU rendering #1526
– Transform & CornerPin: additional «Amount» parameter to control the amount of transform to apply.
– ColorLookup: fix a bug where output was always clamped to (0,1) #1533
– Grade: fix a bug where negative values were clamped even when gamma=1 #1533
– STMap, IDistort, LensDistortion, Transform, CornerPin: reduce supersampling to avoid artifacts
– LensDistortion: add STMap output mode, add undistort output, add PFBarrel and 3DEqualizer distortions model, add proper region of definition support.
– RotoMerge: a merge plugin that takes an external mask as the alpha for the A input.
– WriteFFmpeg: DNxHD codec now supports DNxHR HQ, DNxHR SQ and DNxHR LB profiles.
