Natron. Cada vez van más en serio.

 Acabo de recibir esto:
Natron 2.2 is released. Check it out!

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 if you can help us keep Natron alive.

Commercial support and development of custom features is also available, backed up by Inria ( Please contact our sales department at 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

– 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.

Por fin making The Chemical Brothers ‘Wide Open’


La clave de la dificultad en la pospo del vídeo era el tracking. ¿Como se puede trakear los movimientos con unos acabados tan buenos sin tener que vestir a la bailarina con la típica malla negra con trakers? Esa era mi gran duda. En este vídeo se resuelve. Parece que ya se puede conseguir un buen motion capture sin necesidad de grandes sensores y puntos de track. Bastan unos cuantos puntos discretos sobre la piel… y un buen software.
