Video: Editing shapes

Okay, let's delete all these. I'm just going to draw a big selection square around them and hit the Delete key on the keyboard. Let's take a look at editing shapes. Let's go and get a new Bezier. We'll click and drag, and Return to close. All right, we want to adjust the points of the shape. To make this easier to see, I'm going to turn off the RGBA and set the output to none. So we can just look at the spline. So now we can move the points and see how they look. If you want to insert points, Alt+Command and click on the line to insert points.

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.

Editing shapes

Okay, let's delete all these. I'm just going to draw a big selection square around them and hit the Delete key on the keyboard. Let's take a look at editing shapes. Let's go and get a new Bezier. We'll click and drag, and Return to close. All right, we want to adjust the points of the shape. To make this easier to see, I'm going to turn off the RGBA and set the output to none. So we can just look at the spline. So now we can move the points and see how they look. If you want to insert points, Alt+Command and click on the line to insert points.

To delete points, select the point and hit Delete. Select the point and hit Delete. If you draw a box around several and hit Delete, you'll delete several points. To adjust the tension, select the point, drag the tension arrow, and you will adjust the tension on that one side. Hold down the Shift key to adjust the tension equally on both sides. Move the handles to adjust the slope, and you hold down the Command key to break the continuity at any point.

If you want to restore the continuity, you can select that point, right mouse pop-up, and say smooth. You can also select one or more points, cursor inside the bounding box, right mouse pop-up and say cusp, and that will get you nice big square corners on everything. Again, if you want to put them back, just select those points, and choose smooth and you get back to your Bezier splines. A really nice feature of the new RotoPaint node is the transform handle box.

I'm going to select several points here, and we get this rectangle. Now you see the cursor is shaped as a plus. That means I'm ready to move translate X and Y. If I move out here to the outside corner, I get the little arc. That means we're ready to rotate. If I put it on the edge, I get that horizontal arrow. I'm ready to scale. By the way, if you hold down the Alt key, it will scale towards one edge or the other.

With the cursor on a corner like this, you'll get the diagonal arrows to do a uniform or constrained scale. Put your cursor on the edge, and hold down the Shift key, you can do a skew. We'll undo that. Click off to the side to deselect. So let's talk about adding a feather to the edge. To do that, we're going to set the output back to RGB so we can see what we're doing. We'll select our spline, hold down the Command key and drag out an edge, and there is the feather.

Now the behavior is if you move the inner point, the feather point moves with it. However, if you move the feather point, it moves independently. Now if you want to leave the feather point where it is and still move the inner point, hold down the Command key and now you can move the inner point and it won't move the feather with it. To collapse the feather for one or more points, select the points, right mouse pop-up and say, reset feather. The QuickKey of course is Shift+E. There, I've reset the feather.

If you select the entire shape, you'll get the transform jack right here, which is exactly like the one from the old Bezier node. So we can do the rotate thing. One nice thing they've added is to see the cursor shape looks like an X. I move it inside, it looks like a plus. When you see the X, you know you're ready to scale. When you see the plus, you know you're ready for Translate. Of course, we have the scale in X only, and the scale in Y only, and the skew as before.

Okay, I'll delete the shape simply by selecting the shape and then typing the Delete key. To take a look at how you adjust the B-Spline, it has a little bit of a different characteristic. So we will come back to our Shapes pop-up, select the B-Spline tool, click, click, click, click, click, and Return to Close. What I wanted to show you is how to adjust the tension on each of these control points, a little unusual. Hold down the Shift and the Command key, click and drag horizontally only. Okay, Shift+Command+Horizontal, not vertical, not diagonal.

Okay, to pull out a feather. Same as the Bezier, Command, click and drag. Of course, if you want to adjust the tension of the feather different from the tension of the inner line, you then select the feather point, Shift+Command+Horizontal, click and drag. Again, to undo the feather for however many points you want, select the points, right mouse pop-up, reset feather. The QuicKey is Shift+E. Now that we know how to draw and edit shapes, in our next segment we'll take a look at animating shapes.
