Under the Settings, we have a new feature called snap to markers. When enabled, translation is calculated during tracking. So, you can see if we skip on one frame that our original pattern is contained nicely within the search window here. It’s closer, but it’s still not correct. We will start by loading up the Tracker node. • stabilize 1pt - similar to stabilize, but designed for use with a single track. Or you can invert the values of the data and apply them to the original element - again through expressions - to stabilize the image. This places a track in the center of the Viewer. In this comprehensive course, digital compositing pioneer and Nuke authority Steve Wright introduces this complex and powerful tool to visual effects artists new to Nuke. We have one next, key track current (Shift+C). I have only keyed 60 frames, not the whole lot this time, but I will key track them anyway and just track those 60 frames. For the Transform node they may use 1 (translation only), 2, or N points to find the final transformation, however … If you set this to something other than all or none, you can use the checkboxes on the right to select individual channels. Thanks for … Here we have a hand-held shot, essentially I would like to get a camera track out of this, but the people will interfere with the camera track, so we need to roto them out. Stefan first steps through all the setting you need to know for the camera tracker node. To make this process more efficient, we add a colorcorrect node and increase the saturation and contrast so that the pixels stand out, therefore making it easier for the tracker node to track the pixel. I’m going to cancel that now using the Esc key; this is the same as pressing stop in the toolbar. We are also no longer tracking the center of the ear as we were - we are now tracking slightly to the left. Hello, and welcome to this tutorial on keyframe tracking in Nuke 7.0. • Cubic - remapped pixels receive some smoothing. • median - attempts to remove image noise. Here’s a nice feature of this system. I will move the Tracker to the top circle of the tattoo. (check all that apply). As we can see, we instantly have a much better track. Right here, you have a track field. Sets when the zoom window is visible in the Viewer: • always - the zoom window is always visible. Turn off the tracker node preview. So, basically, I spent more time adjusting keyframes for the problem areas near the end of the timeline. Let’s now go back to our start frame, and adjust our pattern window size to fit just those of the nose, and then track forwards and, again, I will press Esc to cancel. The first thing you will notice is that we have a panel that allows us to store as many tracks as we want - we are no longer limited to the initial four. So, we have a very nice and fast workflow. I could bring in a Read file with a bitmap or, in this case, I will just bring in a Constant to test this (Image > Constant). • match-move 1pt - similar to match-move, but designed for use with a single track. So, through using the Tracker in a combination with Roto we have been able to garbage out the people, and we have also added a User Track to the CameraTracker, so we have been able to put an object in a position of our choice. • remove jitter - transforms the image so that the tracked points move smoothly, with high-frequencies removed. Watch this video on our Vimeo channel . I will hide the progress bar for the moment, and I will create a track in the same position as we did in Nuke 6.3. Increasing the value produces more blur, and decreasing the value less. If you want to track something else, you must craft a new node. If you don't know the camera info, make sure you set lens to unknown and free move. Now what I can do is grab the transform handle for the Constant, and move it so it lines up with the center of the anchor box. One suggestion found. We can see at the right at frame 149 that part of the ear is occluded, and then uncovered here at frame 165. To give you a better idea of what happens when you re-track, recorded in the last tutorial we looked at the track’s error value using the Curve Editor.
