nuke planar tracker tutorial

Now let’s click the track to end button and watch it go. This option locks down the image so that the tracked plane effectively doesn't move - can be very useful for applying drift corrections. It’s important to know that planar track layers interact with other layers. Report. - add or remove a keyframe on the current frame. 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. Nov 8, 2014 - NUKE Planar Tracker Tutorial by Escape StudiosNUKE STUDIO and NUKEX’s Planar Tracker allows you to track areas in your image sequence that lie on a plane. Instead, we’ll go back to our floor track and go to our reference frame. We just need to tweak the roto shape on the cable a little bit. Click to move the playhead to the tracker's reference frame. The amount of smoothing is controlled by the smoothing amount. • CornerPin2D (absolute) - set the to positions to the corners of the planar surface, and the from positions to the dimensions of the currently selected node. You can see if you select the track shape, the selector changes accordingly. PlanarTracker can handle approximately 40% of the surface being covered at any one time, but if the plane is fully obscured, you can manually correct the plane by moving it to a frame where it is not obscured and resume tracking from there. Free Motion Quilting Color Correction Maya Color Schemes. This red color looks like the end of the track pushed this planar surface into an invalid state. To see the results of all our drift corrections, let’s move the corners of our planar surface back to their original positions in the window, and then view the track info. If we move the corner points at any other frame, we are actually applying corrections and we don’t actually want that. We could also add more shapes to this layer if we wanted to hold out more things in this shot. For things like inserting images and set extension, it is nearly always faster and easier to use a planar tracker as opposed to some sort of projection in a camera solve, for example. That concludes our third PlanarTracker tutorial. I will also show you how to use additional track layers to create holdouts for tracks. Hi, I’m Dan Ring and welcome to the fourth tutorial on Nuke’s PlanarTracker. When enabled, you can adjust the plane using the four output indicators in the Viewer. In our example, we drew a shape for the top of the post. In this tutorial, I’m going to show you how we can use back layering to get a better track. Let’s start by creating our PlanarTracker. When enabled, the plane is centered in the Viewer. The Stabilize node applies the exact opposite transform to your footage, so it will make your footage look like it’s standing perfectly still. To start, we need to assess the damage. Create a PlanarTracker node, and connect your footage to the, Draw your roto shape in Roto. As you can see, the logo is sticking very tightly to the back of the panel. This is a context-sensitive toolbar to let you perform your entire tracking workflow from left to right, for example, tracking, display, and correction, and export, all without having to go back to any node properties panel. What we are going to do here is simply track the floor and move our clean plate along with the track. The size of plane is not important as the track relies on the amount of texture in the region - the more texture, the more features can be picked up, the better the track. Now, if we go back to the Merge node, we can set the mask to rgba.alpha, and if we connect that to the Viewer, we should see that we have a nice holdout. TUTORIAL: How To Setup Planar Tracking In Nuke In Compositing Basics, students learn how compositing for both live-action and greenscreen projects and … That all looks pretty good, so let’s throw in our logo and we are good to go. To be specific, they are keyed in the extra matrix knob for the layer. I will also show you how to use additional track layers to create holdouts for tracks. When enabled, a grid corresponding to the current plane is displayed in the Viewer. In particular, we are going to export a Stabilize node and connect it to the Viewer. This is a special type of menu that is used to define what is being tracked. This option places the incoming image entirely inside the planar surface. You can use your tracking results to replace the tracked plane with another image for instance. Click to create the selected node containing the track data. I am going to draw a shape around the window I want to track, just a rough shape, right-click it, and click planar track forward. Now let’s put our logo on. Another nice thing about this is that if the logo were moving, we could simply track it first because it’s in a tracking layer. You can quickly place new 2D elements on a. Efectos Visuales Tutoriales De Arte Alambre Animación Artículos 3d. Click to track forward through a range of frames specified using the frame range control. You can see the Roto shape moved with the correction. It also works for many layers at a time. The next evolution of Mocha. So now our holdout track is done, let’s go back and re-track our boat layer. MochaImport+ for NUKE simplifies using the tracking software mocha Pro with NUKE. To give the features on the boat a decent buffer zone, and I am going to rename the layer to cable. Increase this value to ensure track motion is locally consistent. 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. You can see as we make a correction the Stabilize re-snaps the transform back into place. I will also add a small amount of motion blur to the CornerPin for effect. We can do this from our toolbar, again, making sure the post layer is selected. Mar 17, 2015 - Introduction to The Foundry's NUKEX 6.3 Tutorials on Planar Tracker, by Dan Ring. That track looks very nice and is sticking very tightly to the ground. I first make sure my post layer is selected, and then I click the correct plane button. So when you are at the reference frame, there is essentially no transform being applied. However, when doing this, we need to move the corners of the surface at what we call the reference frame, that is, the frame where we first started the track -- in this case, frame 1. Going back to our original shot, we have set up our PlanarTracker in exactly the same way. Click to track backwards through a range of frames specified using the frame range control. Displays the coordinates of the top right corner of the plane in the Viewer. When enabled, the current plane is displayed in the Viewer. Learn Nuke. Let’s look at our planar surface (correctPlane) just to make sure everything is OK and that the transform wasn't too extreme. We can tweak it in, and it’s good to go. Ordinarily in Roto land, we can simply paint a couple of mask shapes over our first shape. Click to track backward to the first frame of the sequence. FaceTracker is a Nuke node for facial tracking designed to work with models built with FaceBuilder. Nuke Tutorials I will start tracking and I will show you what I mean. Il Planar Tracker di NUKE STUDIO e NUKEX consente di monitorare le aree della vostra sequenza. The PlanarTrackerLayer is also the place where the results of the track are saved to. For our needs, we want a CornerPin2D (absolute). PlanarTracker (NukeX only) is a powerful tool for tracking surfaces that lie on a plane in your source footage. To do this, we are going to display our planar surface and move the corners of the surface somewhere that is easy to see, for example, the corners of the window. Sometimes it happens that you may need to change your reference frame, for example, if an artist drew a Roto or made a clean plate for a frame other than your reference frame. This is now tracking much better in the middle of the shot, but if we look at the beginning, there seems to be something funny happening. If we scrub through the footage, we can see that the cable doesn't change its shape or orientation much. To see our composite, we connect this input up to our clean plate, and we merge it with our original shot. This means anything we put in the layer will be affected by the track. So that track looks pretty good. • Mask Alpha - use the mask input alpha channel to define the plane to track. Straight away, we can see that the cable wipes out the track. 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. • planar-track this shape (fwd) - Select this to track your shape while the track is played forwards. I will start by clearing all the track data to be saved (clear all track data) and then clicking track to end. Let’s clear the drawing handles and play this on a loop so we can see the comp better. Warped surface tracking and roto that sticks. • Perspective - the camera to changes perspective freely. For example, let’s go to the last frame and move the right top-hand corner. Basically, in Nuke they can only output a CornerPin with exactly 4 points, and they map 1 track to each corner of the CornerPin. Normally, you would expect the planar surface to drift away from the window. Now, let’s start the track. Simple to use and faster than most optical flow-based techniques. Instead of using the node menu to create a PlanarTracker, we are going to start with a Roto node and draw the shape of the area we want to track. Particularly, if you look to the top right or the top left of the planar surface. If we turn on the display tracks button, we can see why. NUKE Planar Tracker Tutorial by Escape StudiosNUKE STUDIO and NUKEX’s Planar Tracker allows you to track areas in your image sequence that lie on a plane. Now we are free to move the corners to where we want to place our image. I am going to create the PlanarTracker using the Roto node. We can see here that there is a nice blue sky here with clouds, which would be perfect to pull a chroma key from, and this is exactly what we have done with the Primatte node here. There are lots of options here, depending on how you want to work or what format your mask is in. - browse to the previous and next keyframe. This export option is always baked out in order for the transform to work correctly. Sets a threshold value between 0 and 1. In this tutorial I’m going to show you how to use additional inputs in planar tracking. For example, we want to see how well this part of the window frame tracks over time, and make sure that it also keeps as good a lock as the corners do. It’s also used to define where to place images in the scene. We also have a clean plate of the floor that a kind artist has drawn for us. Now, when we scrub backwards and forwards, we should see this corner tracking a bit better. On what format your mask is in think that there would be some overlap between the CornerPin and the.
