Natron Community Plugins

A collection of Natron plugins made by the community

Installation

To install download the Repo as a ZIP file via https://github.com/NatronVFX/natron-plugins/archive/master.zip

Unzip into any PyPlug folder but the recommended locations are...

Windows: "C:\Program Files\Common Files\Natron\Plugins"

OSX:     "/Library/Application Support/Natron/Plugins"

Linux:   "/usr/share/Natron/Plugins"

Finally edit the plugins location in Natron preferences to allow it to find them during startup, if it's not already. If you want a particular folder only you can use http://kinolien.github.io/gitzip/ and put the URL to the folder you want there. Also you can install individual .py files (and their accompanied png icon files).

Available Plugins

BL/Color

  • bl_Bytes : Converts the picture in another byte space. This is of course a simple simulation as Natron works only in 32 floating point color space.

  • bl_Compress : A common color correction function that pushes the low color to a value and the high color to one another. While tempting to made a color matching between 2 picture this PyPlug might be really usefull.

  • bl_Expand : Does the exact reverse of the Compress node. It stretches the color between to low and high color values.

  • bl_Monochrome : Same as the Shake's Monochrome node. You can play independently with the 3 color components.

  • bl_Slice : Cut a color slice of the picture and create a mask of the result.

  • bl_Threshold : Thresholds the image using a color value, a range of thresholding and a replacement color.

BL/Image

BL/Keyer

  • bl_HSVKeyer : Creates a mask using the hue saturation and value of the color range.

BLWarp

  • bl_Bulge : The Bulge function is a copy of the Bulge inside AfterEffect. This PyPlug is basicaly creating a drop/buble effect on a picture.

Channel

  • ChannelOffset : Easier to use than the basic TransformMasked node, with additional blur option, and auto-edge extension feature.

  • ChannelMerge : ChannelMerge that mimics Nuke's one.

  • Copy_Layer : Copy RGBA channels from the A input to any layer of the B branch.

  • Copy_N : Nuke Copy node.

  • L_ChannelSolo : Easy to use channel selector.

  • Shuffle_N : Inverted Shuffle node.

  • Zmatte : Creates a smooth matte from z-depth pass.

Color

  • L_Icolor : Tint an image from the A input using another one from the B input.

  • lp_Tweaky : Provides a variety of little tweaking-options, like Vibrance, WB-Slider, Tint, etc.

Draw

  • FrameStamp : A very simple stamp that show the current frame in the corner of the image.

  • Gradient : A 3-4 Way gradient.

  • LightWrap_Simple : An alternative to built-in LightWrap plugin, simpler to use, also it as an option to dilate wrap to get a bigger effect.

  • Vignette : This effect reduce the images brightness at the peripherie compared to the image center.

  • WaveForm : Draw a Luminance Waveform of the input image

Filter

  • Light Sweep : Creates Light Sweep.

  • Beauty : Tool designed to achieve skin cleaning jobs.

  • AntiAliasing : Antialiasing filter based on FXAA

  • ChromaticAberrationPP : A filter designed to match real camera chromatic aberration

  • Chromatic_Aberration : Create a stylised Chromatic Aberration effect, similar to the one found in Blender.

  • DePepper : Remove Salt and Pepper noise

  • Defocus : Add a bokeh blur to the image. You can use an image to guide blur size, note that it's not intended to act as a ZBlur plugin.

  • FireflyKiller : Removes fireflies, very bright, nervously jumping around pixels.

  • Mosaic : A basic mosaic effect.

  • Orton : Orton Effect.

  • PM_VectorBlur : Poor Man's Vector Blur. Blur an image according to a Vector/Motion Pass, read the doc to know more about limitation

  • Refraction : Glass distorsion using a UV pass.

  • SharpenPlus : Image sharper.

  • Volume_Rays : Enhanced version of Natron's native GodRays, featuring advanced options.

  • fxT_Glowy : This is an alternative glow effect that mimics the feature of the same gizmo in Nuke.

  • L_BlurHue : A simple hue blur filter.

  • lp_ColourSmear : Smears the colors around a given Alpha.

  • lp_Despot : Despots for black or white pixels.

  • lp_Feather : Feathers your alpha channel

  • lp_fakeDefocus : A very faky Defocus. Very faky. Not very good. Might work for tiny things.

  • lp_roughenEdges : Roughens the edges of a given alpha channel based on an adjustable noise.

Filter/Duck

  • DUCK_Alpha_Edge : It gives edge of a roto or a key, you have the possibility to dilate or erode, blur or multiply the edge differently inside and outside. Simply the best alpha edge you can find for free.

  • DUCK_Denoise : It helps to denoise a footage, since it is not based on analisys: it just provides a denoise for black/white and coloured dots.

  • DUCK_Skin_Cleaner : A tool developped to clean up models skin in common beauty/fashion shots.

  • DUCK_Smart_Blur : Smart Blur isn't a common blur, it helps to blur images with heavy grain, surface imperfections, noises, render problems, etc. keeping the boundary and the edges, and restoring details in highlights and dark regions of the image.

Filter/Pixelfudger

  • PxF_Bandpass : Extract detail from an image. Useful to make plates easier to track.

  • PxF_ChromaBlur : Blur chrominance without affecting luminance. Useful to repair some chroma artifacts in digital video.

Relight
