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®.
Now we have been looking at a closed spline. You can also do an open spline. So I will select the Bezier Spline tool, click and drag, click and drag, click. To indicate you're done adding points, you can either select another tool or deselect over here in the layer list. Now we can edit it. So we will go to the Selection tool, select a line, pull on a control point, maybe adjust the slope, perhaps tweak the tension, and move a control point down here.
Move this up a little bit. Now if we look at the source image, the source spline is correlating this spot here with this spot there and that spot there. Notice this spot is right at the tip of the nose? So if I go to source warped, that spot is still at the tip of the nose. And again, we turn off the Auto Visibility so we can see whatever splines we want, wherever we want, and turn down on the correspondents points so we can see the correspondence lines. Now, I am going to turn the viewer gain down so these are easier to see.
And once again, I will adjust the correspondents points to adjust the nature of the warp. So to hide the correspondence lines, first, I have to deselect from the Correspondence tool, then I can go up here in my Correspondence Visibility line will work. I am going to put the Spline Visibility back to the Automatic mode so it follows whichever source I am looking at, and we will turn the viewer back to 100% brightness to show you this, the Visibility button. Turning off the visibility of a spline means stop doing its warp.
It does not make the spline itself invisible. Okay, it just disables the warp. You can also, if you select more than one spline, up here, this visibility button will turn off all the splines that you have selected. Now that we can draw and edit our source and destination splines, let's take a look at three ways to limit the warping effect.
