As it’s not moving, we don’t need to do anything else with this track layer. It also works for many layers at a time. The way they work is that each track layer will hold out the track layers below it. 2. As it’s not moving, we … We are nearly ready to track, but first we are going to set up our export node, so we can see the results as we are tracking. The tool simplifies the import of tracking data from Imagineer Systems’ mocha Pro planar tracker into Nuke’s Tracker, Roto, RotoPaint, Grid Warp and Transform nodes. This means we can lock our planar apparent motion type to TSR + Shear. NUKE STUDIO and NUKEX’s Planar Tracker allows you to track areas in your image sequence that lie on a plane. A complete comparison is available on … È possibile inserire rapidamente nuovi elementi 2D su una superficie piana, come ad esempio la facciata di un edificio, il pavimento o il lato di una macchina, e quindi animare automaticamente con la … 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. ( Log Out /  Inputs and Controls. Compositing NUKE (planair_tracker) Shooting : canon EOS 60D / tokina 11/17mm music : Melampyre / Hoofbeats on the frozen ground Learn how to remove rig and hold-out layers with the Planar Tracker in The Foundry Nuke 6. 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. 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. Imagineer Systems posts a webinar replay that covered the basics and workflow for using Mocha Pro’s planar tracker and roto tools with The Foundry’s Nuke.. the many ways that mocha Pro is the ideal assist utility for NUKE VFX pipelines. This must include 2D tracking in nuke. 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. To solve this, we need to hold this logo out from the shot. As you can see, the logo is sticking very tightly to the back of the panel. It’s also gone a bit wild here in the Viewer. It’s important to note here that the behavior of the PlanarTracker’s additional input is different than that of the CameraTracker’s. We are then going to open the PlanarTracker node’s properties and change the Additional Input knob. Mar 17, 2015 - Introduction to The Foundry's NUKEX 6.3 Tutorials on Planar Tracker, by Dan Ring. 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. This means you get a much more stable and accurate track compared to traditional 2D pattern trackers. As we want our logo to appear in this frame here, we are going to select our Read node, and then select CornerPin2D (absolute) and, as usual, we create our Merge node. We look at all these in detail in later tutorials. Now let’s click the track to end button and watch it go. I sat down hours to figure out what you did. It’s important to know that planar track layers interact with other layers. 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. Now we can make an observation here that will help our tracking. Internally, each correction keys an offset which allows smooth interpolation of the tracking data. Now, let’s finally export our track data. For our setup, we are going to select Mask Inverted Alpha. I’m going to rename the layer floor. You can quickly place new 2D elements on a flat surface, such as the face of a building, the floor or the side of a car, and then automatically animate with correct perspective as required. New in Continuum 2019 Continuum Mocha Motion Tracker Overview Introduced in Continuum 2019, the BCC Mocha Motion Tracker provides an enormous leap forward in the parameter tracking capabilities in Continuum. I am going to draw a white border around the cable. In these cases, it can be much easier to use a luma or chroma key to specify what areas you want to track, and Nuke’s PlanarTracker lets you do just that. About Planar Tracking. The first is the center planar surface button, which locks the Viewer to the center of the surface. We start by creating a PlanarTracker from the Transform menu. After you have recorded the path of the bubble for the frames where you wanted to do the manual adjustments, you can delete the Paint node again (and e.g. You can quickly place new 2D elements on a flat surface, such as the face of a building, the floor or the side of a car, and then automatically animate with correct perspective as required. New Plug-­in for OFX.Mocha Pro 5 is now available as a plug­-in option for OFX capable host editing and effects applications.This new capability adds unique tools for planar tracking, masking, and object removal and makes them fully accessible in The Foundry’s Nuke and Blackmagic Design’s Fusion Studio. We open up the PlanarTracker node properties and set the Additional Input mask to Mask Inverted Alpha. If we want to, we can draw more shapes inside this layer, which will all contribute to the same track. In this shot, we have a very slow pan from the sky to the ground. Connection Name. Straight away, we can see that the cable wipes out the track. 15 comments. Before you can track a plane, you need to draw one using the Roto node.. We'll begin this project by jumping into the new features only in NUKEX, including the all-new 3D particle system, which allows for new effects like rain, snow, fog, or fire. Mar 17, 2015 - Example how to use Planar Tracker in Nuke for compositing: - for capturing movement (motion analysis) - for rotoscoping (rotopaint node and alpha channels). You can see as we make a correction the Stabilize re-snaps the transform back into place. In our example, we drew a shape for the top of the post. For example, because our cable layer is above our boat layer, the boat shape will have the cable shape removed from it. In this tutorial, we’re going to look at tracking multiple layers. Planar tracking is often better than tracking individual points (with the Tracker node for instance) as it takes a great deal more information into account and gives you a more accurate result. When doing cleanup there are 3 main ways to go about it. We can also turn on display grid lines to help us line up the window perfectly. The way they work is that each track layer will hold out the track layers below it. 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. ( Log Out /  Let’s look at our planar surface (correctPlane) just to make sure everything is OK and that the transform wasn't too extreme. Let’s see what happens if we try to track now. 1. So because our holdout layer is on top, our holdout shape will mask out the logo from the floor shape beneath it. It’s also used to define where to place images in the scene. Here it’s difficult to draw a shape in the first frame that will still exist in the last frame. Input. It’s time to fix this track, and we do this by moving the planar surface corners when they are not on the reference frame. The PlanarTrackerLayer is also the place where the results of the track are saved to. We also have a clean plate of the floor that a kind artist has drawn for us. For example, let’s go to the last frame and move the right top-hand corner. Export dense mesh tracking to many hosts with the new Alembic exporter. And why wouldn't I be able to use planar tracking for inputting a 3D element on a flat surface? Tracking with Chroma-Keys - Planar Tracker Tutorial from Foundry on Vimeo. We do this in exactly the same way as before. NUKEX 6.3 Planar Tracker Tutorial: Rig Removal & Hold-Out Layers from Hieronymus Foundry on Vimeo. Scrubbing through the timeline we can see that the track for this point is actually quite good, however, around frame 35 -- just after the middle -- we can see that it starts to drift slightly downwards. Mocha supports native stereo 3D and 360/VR stereo formats. We can also use the grid to help us line up our surface. We actually have two tools to help us see and correct for drift. If we turn on the display tracks button, we can see why. We want to make certain that our track is good, and not just in those four corners, but in the center of the track as well. Planar DirectLight X. To see how the track went, we can display and move our planar surface on the reference frame, and then scrub through the timeline. This concludes our first tutorial on the PlanarTracker. Things like walls, ceilings, and sides of cars are good examples of planar surfaces, but it can also handle non-planar surfaces, such as faces or people -- generally, the more planar the surface, the better. By including other areas that belong to the same plane, we will end up with better distributed feature tracks and usually a better overall planar track. I am going to speed up tracking to save time. Clicking the export button, you can see there are lots of options depending on what format you would like. This unique workflow uses planar tracking analysis on “both eye views” to reduce manual offsets and tedious keyframe work on stereo 3D rotoscoping, tracking… I am very happy with that track. This sets up a PlanarTrackLayer in the Roto curves panel and an associated PlanarTracker node. It helps expand the alpha channel pixels, so we don't have any features being tracked on the cranes. Now we are free to move the corners to where we want to place our image. Drawing a Plane to Track. Now, create a Merge node and connect it up, setting our input B to our Roto node and our input A to the CornerPin. Let’s start by creating our PlanarTracker. Drawing Roto shapes for tracking on green screens can sometimes be tricky, especially if there are lots of things occluding the screen. I think this is exactly what we want. We also have a Primatte node that I have already set up to pull a chroma key, and an Expression node for some hard cleanup. We want to track the front of this boat in order to put a logo onto it, but if we look through the shot, we can see it becomes occluded by the suspension cable. I have never used keymix node and apply material. As I mentioned before, in the brief of the 2D project, I am required to do cleanup on my original plate. So because our holdout layer is on top, our holdout shape will mask out the logo from the floor shape beneath it. Let’s look at the planar surface to see what’s going on. from Kaloyan Ganev. 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. Going back to our original shot, we have set up our PlanarTracker in exactly the same way. This shows the currently selected track layer and its associated shapes. We now go back to our reference frame and adjust our planar surface to where we want to place our logo. Now, let’s close our display handles and set the track to look so we can see it better. Extra techniques and tricks along the way. When a Roto or RotoPaint node has a PlanarTrackLayer, the tracking toolbar is now displayed in the Viewer. Well, in some cases you can get away with it, particularly if the surface of the occluding object is small. 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. The Planar Tracker is also a very helpful addition to the Roto toolkit in Nuke. To see our composited result, we need to add a Merge node between the CornerPin and the input sequence. Tracking Multiple Layers - Planar Tracker Tutorial, Rig Removal & Hold-Out Layers - Planar Tracker Tutorial, Tracking with Chroma-Keys - Planar Tracker Tutorial, Correcting Tracking Drift - Planar Tracker Tutorial. Hold out mats can be used with a planar tracker so it'll ignore obstructions. Email This BlogThis! This is a special type of menu that is used to define what is being tracked. Now, we add it to its own track layer by selecting it and right-clicking and choosing planar-track this shape. You might think that there would be some overlap between the tools in Nuke and Mocha Pro. Often the real screen, or the area of set that needs to be extended, may have been filmed with a green screen in place. This is a common problem in tracking panning shots, where using the additional input of the PlanarTracker is very useful. In the PT column, you can toggle the purple rectangle according to whether you want the shape to affect the track (rectangle visible) in your planar tracking results or not (rectangle invisible). Planar Tracking can remove objects by finding a clear background at a different time and shearing it to fit into the current time. You will see that at the reference frame the planar surface is yellow. PowerMesh: Mocha’s planar tracking engine now handles warped surfaces with speed and accuracy. This red color looks like the end of the track pushed this planar surface into an invalid state. Tracking camera movement in a 2D footage enables you to add virtual 3D objects to your 2D footage. ( Log Out /  This unique workflow uses planar tracking analysis on “both eye views” to reduce manual offsets and tedious keyframe work on stereo 3D rotoscoping, tracking… As all these tracking tools are natively part of Nuke, that means that round-tripping to dedicated tracking applications is not needed, and when integrated with Nuke's 3D workspace and tools like the Model builder, which can quickly enable you to build a 3D scene with textures without needing to go into a dedicated 3D application like Cinema 4D or modo. In this tutorial, I’m going to demonstrate how you might do some rig removal, using planar tracking and a background plate. Also is MOCHA PRO worth investing, even though I have NUKE STUDIO. Now, what I would like to do is insert this Nuke logo into our post track. To do that, we create a new track layer. First, I will show you what happens if we try to track the boat without using layers. This also means our Roto shape needs to have been drawn at frame 382, which I have already made sure to do so. Function. Source. Roto shape ready for planar tracking. Starting with an introduction to the unique node-based interface and progressing through techniques like color correction, keying, rotoscoping, and tracking, this course covers Nuke from top to bottom. Apr 8, 2016 - The Foundry's NUKEX Tutorials on Planar Tracker: Rig Removal & Hold-Out Layers, by Dan Ring. 2D Point and Planar tracking in Nuke. Quite miraculous when you see it for the first time. We will start from the beginning and work our way to the end. So that seems to look much better. All we need to do is go to our reference frame and adjust our planar surface (correct plane). : 1. The shot has a moving camera (simple roll rotation from above looking down on the product), so my normal workflow in Nuke would be to stabilize the bottle with a planar track, do the cleanup on the stabilized plate, then match-move it back to the original camera motion -- pretty simple setup with two transform nodes linked to a roto planar tracker doing all the work needed. Planar Tracking. 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. We then set the Mask input to our final Crop node, and from this we can start tracking. This is extremely useful when we have multiple track layers. So, as in previous tutorials, we can go back to the reference frame and move the planar surface corners closer to the region we are tracking to fix this. While it’s tracking, let me tell you more about the PlanarTracker. Nuke X also comes with a Planar tracker. I will also rename this layer boat. Nuke’s planar tracker is entirely tied in to the Roto node, relying on Rotoshapes to define areas to be masked or tracked and then outputting Planar transforms to the associate Layer in the Roto shapes list. We now connect the PlanarTracker node’s Mask input to the Expression node, and we’re now ready to track. Planar tracking allows you to identify planes within the image, and to see the way in which they translate and deform across the image sequence. Rig Removal & Hold-Out Layers - Planar Tracker Tutorial from Foundry on Vimeo. Here is a list of the many new features and nodes that are covered in this course in addition to the Particle System and the Planar Tracker. Then, to create a track from within the Roto node, we simply right-click the shape and click planar-track this shape. This means that we can lock the planar apparent motion type to T + Scale, meaning it will only track changes in translation and scale, and usually results in a much better track. Better still, we are going to track the cable and use the track as our holdout. Useful Tutorial for movies and videos that need correction. Nuke has me incredibly confused and I just want to understand why I'm doing xyz, and not just "x=y" etc. I will also add a small amount of motion blur to the CornerPin for effect. 4 years ago. For the tracking itself, almost everything is the same. I am also going to lock the tracking Bezier so we don’t accidentally select and move its control points. As well as position, scale and rotation data, MochaImport+ brings in shear and perspective data; and the Nuke version supports the same “popular stabilized precomp workflow” as the After Effects edition. 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 … This concludes the fourth PlanarTracker tutorial. In particular, we are going to export a Stabilize node and connect it to the Viewer. You can see the Roto shape moved with the correction. Furnace plug-ins. The Dilate node here is very important. To track this screen, we will start with creating a PlanarTracker, but instead of drawing a shape, we are going to leave our track layer empty. This is the exact opposite of what would normally happen. I will rename this layer holdout. Replacing screens with virtual ones, or extending sets, are common planar tracking tasks. A planar track, replacing a side of vehicle, and even faking a reflection, using expressions in Nuke. Il Planar Tracker di NUKE STUDIO e NUKEX consente di monitorare le aree nella vostra sequenza. A very in depth project, involving a 3d model construction, projections, cleanplating (removing an object), and re-projecting a stabilized image. Nuke Studio and NukeX’s Planar Tracker lets you track areas in your image sequence that lie on a plane, allowing for easy placement of new 2D elements on a flat surface and dramatically speeding up common compositing and cleanup tasks. That’s already looking much better, but we're not done yet. This is different from the way you may create a regular holdout in the Roto node. The addition of a Planar Tracker and Nuke's already powerful 2D Point Tracker and 3D Camera Tracker gives Nuke unprecedented tracking tools that will help you solve any conceivable production tracking problem. 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. We also have to disable the center planar surface button to avoid confusion. Hello, my name is Dan Ring, and in this tutorial I’m going to show you how to use the new PlanarTracker found in Nuke 6.3. The furthest away object we want to track is in the bottom-most layer, and, in our case, our boat layer. It’s important to know that planar track layers interact with other layers. Planar tracker overhaul – provides a single, integrated Planar Tracker node with new pattern matching algorithm to make tracking featureless planar surfaces possible Kronos, Vector Generator and Motion Blur 2 – adds a new motion estimation algorithm to improve the quality and temporal consistency of retimed image sequences based on OCULA technology. We can also create whole new track layers, ready for drawing and tracking. That Tracker is ready to use, but first let’s go over what happened. The Stabilize node applies the exact opposite transform to your footage, so it will make your footage look like it’s standing perfectly still. So, you can see now that funny transform has gone away. To fix this, we are going to create a holdout for the cable. At this point, you might be tempted to say the cable does not fully occlude the boat, so why can’t you just track normally?
