Nuke 5 Essential Training was created and produced by Steve Wright. We are honored to host his material in the lynda.com Online Training Library®.
Nuke 5 Essential Training is designed for digital artists already familiar with compositing visual effects using programs like Adobe After Effects or Shake. This course provides a solid foundation in operating Nuke, using the core functions of keying, motion tracking, and color correcting, as well as Nuke’s key strength, 3D compositing. Tour the Nuke user interface, its unique color management system, and overviews of HDR images, masking, keyframe animation, and 2D and 3D motion blur. Exercise files accompany the course.
Sometimes, however, our tracking target is covered up. Now, let's take a look at offset tracking. We'll go back to the beginning of the shot and let's say we needed to track on this corner right here. When I play the clip, we can see that our target is covered up for most of the shot. So, this is a prime case for offset tracking. We'll go back to the beginning of the shot. I'm going to use Tracker 2 for this. I'll turn off Tracker 1, enable Tracker 2, position him on the target.
We'll track forward until the tracker arrow is out. There we go! Now, I'm going to back up until I find my last good frame. It looks like that was my last good frame. I want to clear the data forward so I don't have any bad data, so I will select clear forward. Now to offset this tracker, put my cursor on the tracker. Hold down the Command key, click- and-drag to the offset location here.
Now I can continue tracking from there to the end of the shot. Now my target does reappear. So, I would like to back up and re-track on the target as soon as it's available. So, I'll back up the playhead here and let's say about this frame, it looks pretty good, looks like my target is available. So, I'm going to clear the data forward from this point and to clear the offset, this button right here, clear offset, pops the tracker right back where it was.
Now I can track from here forward to the end of the shot. I now have clean data even though my target is covered up. Now that we have collected some good tracking data, let's see how to use that to stabilize and match-move elements.
