Today our blog will discuss about some powerful Nuke nodes to perform high standard VFX compositing<\/a>.<\/p>\n

As we know that Visual Effects<\/a> or VFX<\/a> has become the integral part of the movie-making and video game industry.<\/p>\n

Highly developed digital software is available in the market for the creation of marvellous VFX compositing in the movies.<\/p>\n

Media Professionals as well as individual filmmakers uses Nuke as digital compositing software which is under The Foundry; a British visual effects software development Company.<\/p>\n

Renowned studios like Digital Domain<\/a>, Walt Disney Animation<\/a>, Dream works Animation<\/a>, Weta Digital<\/a> makes use of Nuke for their production process.<\/p>\n

Nuke is the powerful node-based digital compositing software which helps to achieve exceptional results.<\/p>\n

Multiple Node-Based Nuke<\/u><\/strong><\/h1>\n

\"NUKE<\/p>\n

This 3D node based<\/a> compositing software is a must for any visual effects artist<\/a> in the film and commercial industry.<\/p>\n

Nuke is excellent to do image compositing like Chroma-Keying<\/a>, Distortion, colour management and lot more.<\/p>\n

Nuke offers many things to learn; it has expansive customization, full scripting capabilities and third party library for thousands of toolset and plug-ins<\/a>.<\/p>\n

Nuke has 400 types of nodes to perform infinite functions.<\/p>\n

In Nuke nodes are the building blocks of compositing<\/a>.<\/p>\n

An artist using Nuke can create new composition by inserting and connecting nodes to form a network of operation.<\/p>\n

\"NUKE<\/p>\n

The rectangular box is the node in Nuke.<\/p>\n

The network of nodes allows us to manipulate the image.<\/p>\n

The artist can add nodes using Toolbar, Tab Menu or Right Click Menu.<\/p>\n

When a node is added; Nuke automatically connects it to the currently selected node.<\/p>\n

IBK Colour Node<\/u><\/strong><\/h1>\n

\"NUKE<\/p>\n

IBK colour node is the powerful node in Nuke for Chroma Keying<\/a> technique.<\/p>\n

It gives good result when working with uneven blue or green screens<\/p>\n

IBK Colour<\/a> along with IBK Gizmo is the component of IBK Keyer.<\/p>\n

\"NUKE<\/p>\n

In the above image the foreground of IBK Gizmo<\/a> node is connected to the Plate and IBK Gizmo\u2019s colour is connected to IBK Colour node whereas the viewer node is connected to IBK Gizmo.<\/p>\n

IBK Colour selects the green colour from the background of the footage and IBK Gizmo helps to remove the green colour from the footage<\/p>\n

IBK Colour and IBK Gizmo nodes are added on the working area for the green screen or blue screen keying<\/a> technique.<\/p>\n

From blue or green screen IBK creates the clean plate and IBK Gizmo pulls the key.<\/p>\n

\"NUKE<\/p>\n

If you double click on IBK Colour node the Parameters Panel will pop-up where you can adjust the properties of IBK Colour nodes.<\/p>\n

From the parameters panel you can easily correct any fault regarding the green screen like patches or small screen size etc.<\/p>\n

IBK stacking<\/a> takes place when several IBK Colour nodes are connected one after another to generate clean plate.<\/p>\n

IBK Stacking leads to better clean plate with less messiness from the edge of the foreground.<\/p>\n

IDistort Node<\/u><\/strong><\/h1>\n

\"NUKE<\/p>\n

IDistort node in Nuke enables transformation of an image based on values in the UV Channels.<\/a><\/p>\n

It offers complete control over the UV channels.<\/p>\n

By placing different values in the UV Channel, UV Scale or UV Offset you can give distortions to the specific area of an image.<\/p>\n

You can manipulate the data applied on IDistort node<\/a> at any time.<\/p>\n

\"NUKE<\/p>\n

To apply IDistort node first import an image of a tree.<\/p>\n

Then create IDistort node and connect it with the image then go to UV channel to distort the image and to create sensation of movement in the tree.<\/p>\n

Then create a noise node to give movement in the branches or to create falling leaves.<\/p>\n

Noise node creates maps for warping the footage.<\/p>\n

\"NUKE<\/p>\n

With the IDistort node<\/a> you can create ripple effects of water in the image.<\/p>\n

By creating IDistort and Noise node for water the reflection effects can be generated.<\/p>\n

The above picture is a beautiful example of IDistort.<\/p>\n

In case of advanced level IDistort can be used with matrices and mathematics operations to figure out what changes will occur to the image at pixel by pixel level.<\/p>\n

SmartVector Node<\/u><\/strong><\/h1>\n

\"NUKE<\/p>\n

SmartVector<\/a> has continuously improved within the Nuke software.<\/p>\n

It has come up with new features addition to improve the vfx<\/a> image compositing.<\/p>\n

The powerful SmartVector node can analyze the movement of each pixel in the frame and create motion vectors to match.<\/p>\n

The data of information can be used with VectorDistort node for application.<\/p>\n

SmartVector helps to perform many herculean tasks which are difficult to achieve frame by frame.<\/p>\n

Smart Vector enables the vfx artist<\/a> to work on one frame in a sequence and then use motion vector information to correctly transmit the work in the rest of the sequence.<\/p>\n

SmartVector node generates the vectors using motion data captured from the image and then channels it into VectorDistort node to warp the work.<\/p>\n

From creating body mark, tattoo, paint or clean up Smart Vector can be used to perform wide range of tasks.<\/p>\n
