I am going to speed up tracking to save time. That concludes our third PlanarTracker tutorial. MochaImport+ for NUKE simplifies using the tracking software mocha Pro with NUKE. Original shot from Transformers: Dark of the Moon (2011) by Michael Bay. We can see this track is sticking a lot tighter than before, and that concludes the fifth PlanarTracker tutorial. Now we are free to move the corners to where we want to place our image. As soon as we have done that, our track should look much better. We connect that up, and we create our Merge node as usual. A planar track, replacing a side of vehicle, and even faking a reflection, using expressions in Nuke. 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. This creates a new planar tracking layer for the shape and attaches the shape to it. 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. For the tracking itself, almost everything is the same. In this case, absolute means the input image will be fit into the bounds of the planar surface. I will also close all of the properties panels. This is a common problem in tracking panning shots, where using the additional input of the PlanarTracker is very useful. About Planar Tracking. Let’s put this track on a loop so we can see exactly what's happening. 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. Now, this track is starting to look a lot better, just apart from this logo here sneaking in. This will automatically connect the CornerPin and select the correct image format. Now, it looks like the PlanarTracker has done a reasonable job, but it’s not quite spot on, and we want to fix that. So because our holdout layer is on top, our holdout shape will mask out the logo from the floor shape beneath it. 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 will start by clearing all the track data to be saved (clear all track data) and then clicking track to end. Now, if we scrub along we can see that looks much better. Share to Twitter Share to Facebook ← Newer Post Older Post → Home. 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. To be specific, they are keyed in the extra matrix knob for the layer. To do this, I need to define where in the image I want the logo to be placed and then export my track data. A planar track, replacing a side of vehicle, and even faking a reflection, using expressions in Nuke 2. Let’s click the go to reference frame button, just in case we forgot where we started. A significant new release for tracking, roto and VFX. To see our composited result, we need to add a Merge node between the CornerPin and the input sequence. Before you can track a plane, you need to draw one using the Roto node.. Learn the proper setup to add a holdout mask for the Planar Tracker. This unique workflow uses planar tracking analysis on “both eye views” to reduce manual offsets and tedious keyframe work on stereo 3D rotoscoping, tracking… Mocha supports native stereo 3D and 360/VR stereo formats. You might think that there would be some overlap between the tools in Nuke and Mocha Pro. However, the PlanarTracker system has its own way of creating holdouts. We now go back to our reference frame and adjust our planar surface to where we want to place our logo. To solve this, we need to hold this logo out from the shot. 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. 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. You can now use the full power of Mocha’s planar tracking engine to drive geometric parameters such as light or emitter locations directly within the Continuum effect. In this shot, we have a green screen that we want to track and replace with our logo. 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. The Foundry Visionmongers Limited is registered in England and Wales. In this NUKE Tutorial, we'll learn how to use the new features introduced in NUKE 6.3, like 3D particles, the Planar Tracker, Denoise, Spline Warp, Audio Read, presets and more. We can also use the grid to help us line up our surface. NUKEX 6.3 Planar Tracker Tutorial: Rig Removal & Hold-Out Layers from Hieronymus Foundry on Vimeo. ( Log Out /  ( Log Out /  Furnace plug-ins. So, now let’s look at the alpha channel of our Roto node. 1. I will start tracking and I will show you what I mean. Now we can make an observation here that will help our tracking. 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. So because our holdout layer is on top, our holdout shape will mask out the logo from the floor shape beneath it. Here it’s difficult to draw a shape in the first frame that will still exist in the last frame. As you can see here, from the Expression node’s mask overlay, this is exactly what we want. NUKE's built-in planar tracker vs Mocha Pro. This is different from the way you may create a regular holdout in the Roto node. In this tutorial, we’re going to look at tracking multiple layers. We just need to tweak the roto shape on the cable a little bit. Now, create a Merge node and connect it up, setting our input B to our Roto node and our input A to the CornerPin. Extra techniques and tricks along the way. The way they work is that each track layer will hold out the track layers below it. 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). NOTE: This footage has been used for self-educational purposes only. In this tutorial I’m going to show you how to use additional inputs in planar tracking. 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. In fact, the Roto node is essential for the PlanarTracker to work, so always try and keep them connected. If we wanted, we could repeat this process of moving reference frame corners and tweaking them elsewhere as much as we want, each time improving the track. You can see that, this time, the track is perfect. Using the Additional Mask Input. If we look at the sides of the boat, we can see they are roughly on the same plane as the area we want to place our logo. So let’s draw these areas in two. This shows the currently selected track layer and its associated shapes. Didnt thought about holdout using a cylinder. 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. The way they work is that each track layer will hold out the track layers below it. You will see that at the reference frame the planar surface is yellow. Email This BlogThis! This already makes drift much easier to see and is perfect for most cases. I have just remembered something that will probably affect the track, so I am going to stop it and go back to our original footage. 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. That Tracker is ready to use, but first let’s go over what happened. Planar Tracking. Roto shape ready for planar tracking. Compositing NUKE (planair_tracker) Shooting : canon EOS 60D / tokina 11/17mm music : Melampyre / Hoofbeats on the frozen ground All we need to do is go to our reference frame and adjust our planar surface (correct plane). 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. Hello, I’m Dan Ring and welcome to the second tutorial to Nuke’s new PlanarTracker. Then, to create a track from within the Roto node, we simply right-click the shape and click planar-track this shape. Mar 17, 2015 - Introduction to The Foundry's NUKEX 6.3 Tutorials on Planar Tracker, by Dan Ring. Correcting Tracking Drift - Planar Tracker Tutorial from Foundry on Vimeo. Right, so the tracking is finished, and if we scrub back and forth across the timeline, we can see it has done a very good job. Join Steve Wright for an in-depth discussion in this video, Planar Tracker workflow, part of Nuke Essential Training (2014). Nuke Studio includes all the features of NukeX plus a timeline editor for basic video edition. This is particularly useful on flat, featureless surfaces, such as the cable. Change ), You are commenting using your Facebook account. 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. For our setup, we are going to select Mask Inverted Alpha. We look at all these in detail in later tutorials. - [Steve Wright] Hi this is Steve Wright welcoming you to this week's Nuke Nugget. If you look at the logo, you can see a lot of features are being tracked here and are biasing the track. This looks like a pretty reasonable track and, importantly, it covers most of the overlap area between the cable and the boat. CameraTracker (NukeX and Nuke Studio only) is designed to provide an integrated camera tracking or matchmoving tool, allowing you to create a virtual camera whose movement matches that of your original camera. Nuke has me incredibly confused and I just want to understand why I'm doing xyz, and not just "x=y" etc. 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. To see our composite, we connect this input up to our clean plate, and we merge it with our original shot. Which one do you think better than the other? 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. Normally, you would expect the planar surface to drift away from the window. 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. Straight away, we can see that the cable wipes out the track. That’s already looking much better, but we're not done yet. The PlanarTrackerLayer is also the place where the results of the track are saved to. Click the link below to watch full tutorial : NUKEX 6.3 Planar Tracker Tutorial: Rig Removal & Hold-Out Layers. A very in depth project, involving a 3d model construction, projections, cleanplating (removing an object), and re-projecting a stabilized image. I have never used keymix node and apply material. Instead, we’ll go back to our floor track and go to our reference frame. This concludes our first tutorial on the PlanarTracker. You can use the PlanarTracker to track rigid objects and objects that deform slightly throughout the track. As it’s not moving, we … You can see the Roto shape moved with the correction. I’m going to speed up the recording to save time. 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. For example, because our cable layer is above our boat layer, the boat shape will have the cable shape removed from it. It’s important to note here that the behavior of the PlanarTracker’s additional input is different than that of the CameraTracker’s. The important thing to remember is that planar tracking tracks regions as opposed to small image patches. Planar DirectLight X. PlanarTracker is a powerful tool for tracking surfaces that lie on a plane in your source footage. NUKE STUDIO and NUKEX’s Planar Tracker allows you to track areas in your image sequence that lie on a plane. Planar tracking is a much more artist friendly way of working than traditional 3D tracking and mocha Pro is full of features which will speed up your workflow for a huge range of VFX features. Well, in some cases you can get away with it, particularly if the surface of the occluding object is small. 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. NukeX adds advanced tools including planar tracking, 3D camera tracking, point clouds and 3D model builder, particle systems, lens distortion and advanced retiming. Stereo 3D planar tracking, masking, and object removal workflow. I have already created a custom Transform node here to warp the logo to where I want it in our reference frame.
