So we are nearly done, however, if we look at our output, you will see the logo is appearing over the cable. Better still, we are going to track the cable and use the track as our holdout. The tracker works differently than the Nuke tracker regarding the “Transform” part. Once it is created, we can start drawing the area we want to track straight away. This means that the transform at this point is extreme compared to the reference frame. In this shot, we want to track the top section of this post here. Live-action… 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. Planar DirectLight X. We could also add more shapes to this layer if we wanted to hold out more things in this shot. If we want, we can use the grid to help us line up our corners. And why wouldn't I be able to use planar tracking for inputting a 3D element on a flat surface? Instead, we’ll go back to our floor track and go to our reference frame. Let’s look at our planar surface (correctPlane) just to make sure everything is OK and that the transform wasn't too extreme. I’m going to rename the layer floor. 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. Using the Additional Mask Input. 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. We can also create whole new track layers, ready for drawing and tracking. Tracking camera movement in a 2D footage enables you to add virtual 3D objects to your 2D footage. This is useful for instance if you have the results of a chroma keying that you want to use with your primary mask. The planar tracker recognizes this bubble and starts to track it (as long as the white bubble is within the your tracking polygon). 2. So let’s draw these areas in two. 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. Posted on November 26, 2018 December 10, 2018 by James Pratt. PowerMesh sub-surface tracking drives warp stabilization, mesh warped roto-splines, and more. While it’s tracking, let me tell you more about the PlanarTracker. We do this in exactly the same way as before. 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. Now we can make an observation here that will help our tracking. We will start from the beginning and work our way to the end. When we created the PlanarTracker, you will notice it also created a Roto node as well, this is to allow very tight integration of planar tracking with Roto. That frame looks pretty good; let’s see how we did. 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. Nuke X also comes with a Planar tracker. 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. Export dense mesh tracking to many hosts with the new Alembic exporter. This means anything we put in the layer will be affected by the track. This usually happens on these kind of shots when the camera is moving into the scene. Introduction to Planar Tracker Tutorial from Foundry on Vimeo. ( Log Out /  I am going to draw a white border around the cable. I am also going to lock the tracking Bezier so we don’t accidentally select and move its control points. This looks like a pretty reasonable track and, importantly, it covers most of the overlap area between the cable and the boat. In this shot, we have a very slow pan from the sky to the ground. 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. As you can see, the logo is sticking very tightly to the back of the panel. The Planar Tracker is also a very helpful addition to the Roto toolkit in Nuke. Finally, let’s place our logo into the sky plane to see how we did. 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. Useful Tutorial for movies and videos that need correction. To start, we need to assess the damage. 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. 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. Before we export an absolute, we can save ourselves some time by selecting the Read node and then clicking the export button. This unique workflow uses planar tracking analysis on “both eye views” to reduce manual offsets and tedious keyframe work on stereo 3D rotoscoping, tracking… So that seems to look much better. Drawing a Plane to Track. This is extremely useful when we have multiple track layers. Nuke Studio includes all the features of NukeX plus a timeline editor for basic video edition. So that track looks pretty good. ( Log Out /  So now our holdout track is done, let’s go back and re-track our boat layer. This is exactly what we want. So when you are at the reference frame, there is essentially no transform being applied. Your new shape’s boundaries appear purple in the Viewer, and a Bezier shape item appears in the stroke/shape list. First, I will show you what happens if we try to track the boat without using layers. This means you get a much more stable and accurate track compared to traditional 2D pattern trackers. Let’s now close these property panels to get a better view. Roto shape ready for planar tracking. This red color looks like the end of the track pushed this planar surface into an invalid state. With the PlanarTracker, you use it to specify what areas you want to include in the track, whereas in the CameraTracker, you use it to exclude regions. 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). We then set the Mask input to our final Crop node, and from this we can start tracking. The way they work is that each track layer will hold out the track layers below it. If we look inside the Roto node, we will see a PlanarTrackLayer in the curves menu. In this tutorial, I’m going to demonstrate how you might do some rig removal, using planar tracking and a background plate. A planar track, replacing a side of vehicle, and even faking a reflection, using expressions in Nuke 2. Notice that the shape outline is colored purple to indicate it is in a track layer and will be used to define a region. Apart from looking very weird, it makes it very easy to look at, and correct, drift corrections. 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. 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. We now connect the PlanarTracker node’s Mask input to the Expression node, and we’re now ready to track. As in the previous tutorial, we will select our Read node and export a CornerPin using the absolute mode. Let’s clear the drawing handles and play this on a loop so we can see the comp better. Now, this track is starting to look a lot better, just apart from this logo here sneaking in. The Foundry Visionmongers Limited is registered in England and Wales. In this shot, I want to track this window here, but I know that the window is difficult to track because of the reflections, motion blur, and lens distortion. Join Steve Wright for an in-depth discussion in this video, Planar Tracker workflow, part of Nuke Essential Training (2014). 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 … We look at all these in detail in later tutorials. We can see this track is sticking a lot tighter than before, and that concludes the fifth PlanarTracker tutorial. As I mentioned before, in the brief of the 2D project, I am required to do cleanup on my original plate. We just need to tweak the roto shape on the cable a little bit. This has two implications: one, that we are going to supply an alpha channel on the PlanarTracker node’s Mask input, and two, that by saying inverted mask, our track region will be specified where the pixel’s alpha is 0. Change ), You are commenting using your Google account. NUKEX 6.3 Planar Tracker Tutorial: Rig Removal & Hold-Out Layers from Hieronymus Foundry on Vimeo. Stereo 3D planar tracking, masking, and object removal workflow. 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. As soon as we have done that, our track should look much better. As we don’t want any transform on the reference frame, and we don’t want to place our clean plate inside the planar surface, we can select the CornerPin2D (relative). 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. A complete comparison is available on … Apr 8, 2016 - The Foundry's NUKEX Tutorials on Planar Tracker: Rig Removal & Hold-Out Layers, by Dan Ring. This is "old homework - nuke - planar tracker" by Louis-Pierre Sasseville on Vimeo, the home for high quality videos and the people who love them. Posted by copiwp on December 20, 2012. Now we are free to move the corners to where we want to place our image. Also is MOCHA PRO worth investing, even though I have NUKE STUDIO. You can see that, this time, the track is perfect. 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. 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. Mar 17, 2015 - The Foundry's NUKEX 6.3 Tutorials on Planar Tracker: Tracking Multiple Layers, by Dan Ring. 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. In fact, the Roto node is essential for the PlanarTracker to work, so always try and keep them connected. It’s important to note here that the behavior of the PlanarTracker’s additional input is different than that of the CameraTracker’s. 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. If we scrub through the shot, you can see the surface has turned red for those strange frames. The idea here is to try to track the sky in order to put a logo onto it. Drawing Roto shapes for tracking on green screens can sometimes be tricky, especially if there are lots of things occluding the screen. 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. Here it’s difficult to draw a shape in the first frame that will still exist in the last frame. There are lots of options here, depending on how you want to work or what format your mask is in. To see how the track went, we can display and move our planar surface on the reference frame, and then scrub through the timeline. We will get rid of the drawing handles and see how that track went. Notice that I am moving the planar surface on the reference frame, and remember that any changes I make to the planar surface on the reference frame ripple throughout the shot. This means we don’t want to create an absolute CornerPin node, we actually want a relative CornerPin node. I have already created a custom Transform node here to warp the logo to where I want it in our reference frame. Scrubbing through the timeline, we can see the track is slipping more and more as the track goes on. Going back to our cable track shape, you can tighten it out a bit and use it as a mask. If we look at the feature tracks, we can see some very pretty, bird-like features in the sky. We actually have two tools to help us see and correct for drift. 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. The idea is to order your layers in the curves menu by their distance from the camera, so that the object drawn in the topmost track layer is closer to the camera and, in our case, our cable layer. In particular, we are going to export a Stabilize node and connect it to the Viewer. This is the exact opposite of what would normally happen. Camera tracker (and matchmoving as a whole) allows you to extract the position and characteristics of a camera from its sequence, as well as the 3D positions of features within the scene. 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. 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 do that now. Planar Tracking. Software required: NUKE … In this shot, we have a green screen that we want to track and replace with our logo. For the tracking itself, almost everything is the same. We start by creating a PlanarTracker from the Transform menu. If we scrub through the footage, we can see that the cable doesn't change its shape or orientation much. This must include 2D tracking in nuke. I will rename this layer holdout. 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 can also use the grid to help us line up our surface. You can see as we make a correction the Stabilize re-snaps the transform back into place. I just want to understand the rationale! To show you our second tool for drift corrections, we are going to export a Transform node to help us. 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. To solve this, we need to hold this logo out from the shot. If we turn on the display tracks button, we can see why. The Stabilize node applies the exact opposite transform to your footage, so it will make your footage look like it’s standing perfectly still. Let’s look at the planar surface to see what’s going on. This shows the currently selected track layer and its associated shapes. Hi, I’m Dan Ring and welcome to the fifth tutorial for Nuke’s new PlanarTracker. New in Mocha Pro 5. I am going to speed up tracking to save time. Didnt thought about holdout using a cylinder. 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). This means we can lock our planar apparent motion type to TSR + Shear. The PlanarTrackerLayer is also the place where the results of the track are saved to. This means I want 382 to be my reference frame, and we do this by starting our track at frame 382. Again, beginning at frame 382, and tracking to the beginning of the shot. Now let’s put our logo on. NUKE's built-in planar tracker vs Mocha Pro. Mar 17, 2015 - Introduction to The Foundry's NUKEX 6.3 Tutorials on Planar Tracker, by Dan Ring. Now, we add it to its own track layer by selecting it and right-clicking and choosing planar-track this shape. Straight away, we can see that the cable wipes out the track. ( Log Out /  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. For our setup, we are going to select Mask Inverted Alpha. So, now let’s look at the alpha channel of our Roto node. 1. I’m going to speed up the recording to save time. 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? For now, the most useful knob here is the planar track layer selector.
