This course reviews the Nuke 6.3 tools and performance enhancements that make keying, motion tracking, color correction, and 3D compositing in Nuke more powerful than ever. Author Steve Wright covers the introduction of 3D particles, the enhanced spline and grid warping, the all-new planar tracker, an audio scratch track for matching audio cues to effects, and a briefing on deep compositing, the powerful new method of working with deep images.
Nuke 6.3 New Features was created and produced by Steve Wright. We are honored to host his material in the lynda.com library.
For a moving camera shot, the next step is to enable keyframing. So go to the Locator tab and select Key All Locators. You must do this before you move the playhead, okay. So, now let's go to the last frame in the clip, slide over here and I will use the last frame button. The key point about the process is you are only going to get the camera solve between your first and last keyframe. So you need it for the whole shot, you have to have keyframes on the first and the last frame of the clip.
Okay, now we are ready to reposition the locators for new keyframe. When I click and drag this, you see the line that it leaves behind. That's your cue that you have in fact set keyframing. If you have forgotten to do that, you won't see that line. So back up to the start frame, set your keyframing and come back to the last frame. Okay, so we will just slide these guys to their same locations on the new frame. Okay then zoom in and refine, like I said the more accurate you do this, the better your camera solve will be.
Okay, now let's do one keyframe in the middle of the shot. So we will slide the playhead out to frame 50, correct all the locators for the new keyframe. You see the keyframing interpolated in a straight line, but these targets are moving in a curve. So we're telling it where the locators are on one of the frame and it will use all of the frames that we have keyframed here to compute the camera location. And by the way, you don't have to keyframe every point on every frame.
The interpolation algorithm will only use those points that you have in fact keyframed. Okay, I will re-home the Viewer with the H key and the Node Graph with the F key. By the way, you can use the Projection Solver on a still shot. Just line up your locators in 2D, you do not set keyframes and you just build your camera from the one frame. You can also use a Tracker node for example if you wanted to. You could like track on one of these points and then copy and paste the tracker data into the locator data here.
Now that we've established the correlation between the 3D points and the 2D points, we are ready to do the camera solve.
