Author Steve Wright explores the new features found in the 3D digital compositor Nuke 6. The course introduces the RotoPaint node for drawing and painting effects, the Keylight keyer for creating mattes and composites, and the SplineWarp node for warping images. The course also explains how to merge keys, animate with keyframes, and create image-based blurs. Exercise files accompany the course.
Nuke 6 New Features was created and produced by Steve Wright. We are honored to host his material in the lynda.com Online Training Library®.
I have loaded a fresh new RotoPaint node so that we can take a look up here at the Shapes list. This is the area that keeps a list of all the shapes as you draw them and you can use this area to re-order the layering or rename them or do copy and paste and it even allows you to edit some common property attributes. Let's take a look. I will punch up the Bezier tool and remember when you punch up a tool the settings up here control how it will be created. So I am going to initially set this to be red, so I will be creating a red shape, hit Return to close, create another shape. This time, I will preset it to make it green, draw that shape, Return to close.
One more, and this one we will make blue. Okay, all three of these shapes have been entered into the list and their order in the list controls the compositing order. I can also rename them. So I am going to rename this one blue, name this one green, and we will name this one red. Baecause it's always a good idea to help keep your production as organized as possible.
Right now red is at the bottom of the stack, so the green and the blue are on top. If I click and drag this icon up, I put red at the top of the stack, and now it is on top of the blue and the green. You can also copy and paste. I will select the green shape, right mouse pop-up, Copy. Select the root folder before you do the Paste. Otherwise you will paste over the attributes of another shape. I now have two green nodes, green and green1. I will do an Undo to get rid of that green1 copy, and now we will look at the Property shortcut icons that are here in the list.
This first icon is the Visibility button. The next one is a Lock or Unlock. This allows you to lock a shape so you don't accidentally edit it. This icon here is the Color, so we can double-click on that and even change it to a new color if we wish. I will put that back. This is the Invert icon, and this icon here gives you the Blending mode option pop-up list if you want to change the blending mode from here. This icon is Motion Blur. If you turn that on, you have enabled motion blur for that shape.
Turn it off, and it's disabled and this column simply reports the current lifetime setting for that shape. If you have a lot of shapes and strokes in a RotoPaint node, the processing can get a little slow because the node gets heavy. You can help that by turning the visibility off, so that will lighten the processing load. So the screen updates will be faster. I will return the visibility here to show you another very important new feature, the grouping function.
You can create a folder and put as many shapes as you want inside of a folder and then you can change the attributes of that folder and all the shapes inside will inherit it. Let me demonstrate. If you will select a shape and hit the plus sign, the folder will simply be created above it. It does not put the shapes inside. It's simply that's where it is going to be placed in the stack. To put the shapes inside the folder, I select them and then drag them and drop them inside it, and now I can rename the folder. I will call it foo.
I can hide the contents of the folder. Now here is the really kicky bit. If I select the folder, now the Common, Transform and Shape tabs are now connected to the folder, and everything I do will be inherited by all the shapes. For example, I can go to the Opacity and drop the transparency and the green and blue shapes inside the folder will lose their opacity. We will put that back. I will go to the Transform tab. Here, I can transform all the shapes together inside this folder.
there they are, they are moving together. Or go over to the Shape tab and increase the Shape tab attributes like the Feather, and all of the shapes inside the folder will inherit that attribute. Now we are ready to take a look at the Output settings for the RotoPaint node up here.
