• Clone tool: Ctrl/Cmd+click and drag to set the clone offset. I’m going to have a brief look at the other tools before moving onto wire removal. We are prompted to save it as a new script. You can also adjust rotate values by dragging the transform handle in the Viewer. As we create a normal shape, we can pull out handles. Typically, you would position the stroke, shape, or group correctly in the hero view, then split this control, and drag the stroke or shape to its correct location in any other views. And now, we can align our right eye to our left eye. Visual effects (VFX) dominate at the box office, and Nuke is the compositing software that is used to create mind-blowing effects at the highest end studios. This allows you to apply changes throughout the entire animation, from start to the frame you are on, or to end of the shot, or between a range of keyframes. The result is always a lighter color. Click on a toolbar item to cycle through the available options for that class of tools. • B-Splines: Ctrl/Cmd+Alt+drag on a point to adjust its tension. You need to wait a long time before they all update. The roto node's sophistication gives it great power and flexibility to solve a number of masking problems. Similar colors will return black pixels. I will start on Nuke 6.3v8 because there are a number of improvements to the operability of RotoPaint in Nuke 7.0, and I want to remind you of some of the problems that exist in the previous version of Nuke. To offset a point, simply click and drag it in the Viewer to the correct position. • exclusion (A+B-2AB) - creates a result similar to the difference mode but lower in contrast. I made a roto shape for image 1 and merged with image 2, so 1 is over 2, minus the roto'd bit from 1. And now if we look at that, we will see the shape is now moving as required. I will set their lifetime type to all frames, and I have a Tracker here that has tracked both sides of the rope. Plus is similar to the screen blending mode, but produces a more extreme result. Sets the rate of opacity falloff at a feathered edge for a shape. In this tutorial, we will look at the basics of animation in Roto and RotoPaint. The points will stay cusped unless you specifically ask them not to be (Z). So now we have a roto that is following the shape of the hood, but this is working on our stabilized image and we want it to work on the original image. So I will select the stroke, go into the Clone parameter, set a key, and I will just turn off the overlay for the moment by pressing O. If I then turn it off and click on the image, it deselects the shape. shape motion blur determines the exposure for each moving shape and blends the resulting blurred shape. • max (max(A,B)) - selects the lighter of the two colors as the resulting color. –Shake users: Separate roto nodes for Ryan and Brandon. So in this case, I have to explicitly add a keyframe before I can continue. This could be a series of paint strokes or layers, and as you can see as I drag-and-drop, it’s taking quite a while to update. So now I will add a new Layer/Group and call this rope cleanup, and I will move both of these 2 clones into that layer. Adjusts the center of rotation and skew on the x and y axes. What I really want to do is deal with this point’s keyframes only, so we will undo that (Cmd/Ctrl+Z). With the Smear, however, although the effect parameter is available, it has no apparent effect. I will just undo that and check to see if I need to create a keyframe. This may be more efficient than the global motion blur since each shape will only be blended once. Spins the selected shape, stroke, or group around the pivot point. This allows you to use the Tracker's transform functions to stabilize, reduce jitter, and so on. I will start off looking at the normal Bezier and compare it with the Cusped Bezier. You also have within the Stroke tab and the time offset in the Clone tab the ability to split the eyes as well. The best approach is one of extreme curiosity. Sets how the colors in the current shape (A) are merged with the underlying image and shapes (B): • color-burn (darken B towards A) - darkens B to reflect A by increasing the contrast. When enabled, create a link between RotoPaint and the exported node, so that when the track updates, the points are updated too. Here I have a greenscreen that I created using a number of clones and reveals from various different frames. For those that are used to working in RotoPaint, you will know the more paint strokes you have, the slower Nuke gets. Set it to “none,” versus “add” or “subtract.” Why peek through a mask to see what’s being worked on? Now, let’s have a look at the difference between animating the shape directly and the Transform controls. Sets the number of motion blur samples for all shapes in the current RotoPaint node. This time, I will take a second shape and change its blendingmode or I can Shift+select more than one and change all their colors or blending modes in one go. Output mask channel. If I open up the RotoPaint node and I go into his face and paint a line, you will see it doesn't line up in the same place on the right eye. • Nuke as standard comes with a ReConverge node. I’m going to paint over the erase strokes. If you check feather link in the Roto tool settings above the Viewer, you can move the shape point and the feather point together. You can adjust the blur amount using the effect control. Because the layer list works top down, this is now on top of the erase strokes, but if I move this layer below the erase strokes, they are now cutting through it.
