When enabled, the current plane is displayed in the Viewer. Let’s now close these property panels to get a better view. When enabled, a grid corresponding to the current plane is displayed in the Viewer. We do this in exactly the same way as before. • keys - displays the current and total number of keyframes. I will start by clearing all the track data to be saved (clear all track data) and then clicking track to end. Free Motion Quilting Color Correction Maya Color Schemes. We will clear out all of the track data and we will re-track. First, I will show you what happens if we try to track the boat without using layers. Arland Nakia. In this tutorial I’m going to show you how to use additional inputs in planar tracking. 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. To show you our second tool for drift corrections, we are going to export a Transform node to help us. 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. Hi, I’m Dan Ring and welcome to the fifth tutorial for Nuke’s new PlanarTracker. If we move the corner points at any other frame, we are actually applying corrections and we don’t actually want that. Now, that track of the sky looks really solid, and you can see how easy it was to specify the track region using a chroma key instead of using roto shapes. Displays the coordinates of the bottom left corner of the plane in the Viewer. It’s very useful for clean up, face replacement, digital makeup and other tasks that require… When a Roto or RotoPaint node has a PlanarTrackLayer, the tracking toolbar is now displayed in the Viewer. We could also add more shapes to this layer if we wanted to hold out more things in this shot. 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. 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. As you can see, the logo is sticking very tightly to the back of the panel. Now, let’s close our display handles and set the track to look so we can see it better. Sets what type of camera movement is expected: • T + Scale - both translates and scales. 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. MochaImport+ for NUKE simplifies using the tracking software mocha Pro with NUKE. • Tracker - creates a four-corner Tracker node with each of the trackers taking the positions of planar surface corners. 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. It helps expand the alpha channel pixels, so we don't have any features being tracked on the cranes. If you look at the logo, you can see a lot of features are being tracked here and are biasing the track. This threshold controls how similar features look over a number of frames. In this shot, we have a very slow pan from the sky to the ground. • Mask Luminance - use the luminance of the mask input to define the plane to track. 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. TUTORIAL: How To Setup Planar Tracking In Nuke In Compositing Basics, students learn how compositing for both live-action and greenscreen projects and … Let’s see what happens if we try to track now. Normally, you would expect the planar surface to drift away from the window. So now our holdout track is done, let’s go back and re-track our boat layer. In this tutorial, I’m going to show you how we can use back layering to get a better track. Click to track forward to the last frame of the sequence. In fact, the Roto node is essential for the PlanarTracker to work, so always try and keep them connected. For our needs, we want a CornerPin2D (absolute). 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. • 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. Click to clear all tracking information forward of the current frame. It gets automatically linked up with PlanarTracker. 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. This concludes the fourth PlanarTracker tutorial. 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. We will start from the beginning and work our way to the end. I’m going to speed up the recording to save time. Simple to use and faster than most optical flow-based techniques. So that seems to look much better. I am going to create the PlanarTracker using the Roto node. You can also drag-and-drop matrix values from another plane to apply those values, for example, if you wanted to align planes in a scene. Finally, let’s place our logo into the sky plane to see how we did. In this shot, we have a green screen that we want to track and replace with our logo. PlanarTracker (NukeX only) is a powerful tool for tracking surfaces that lie on a plane in … 1 min lettura. You can adjust the indicator’s position by dragging it in the Viewer or by copying and pasting coordinates from other controls. Now, this track is starting to look a lot better, just apart from this logo here sneaking in. There are lots of options here, depending on how you want to work or what format your mask is in. 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. Visual effects dominate at the box office, and Nuke is the compositing software that is used at high-end studios to create those mind-blowing effects. If you ever noticed your Nuke script size is large, the tracking data from CameraTracker can be one of the culprit. Now, if we scrub along we can see that looks much better. We are then going to open the PlanarTracker node’s properties and change the Additional Input knob. As it’s not moving, we don’t need to do anything else with this track layer. This already makes drift much easier to see and is perfect for most cases. It also works for many layers at a time. I know that our clean plate was drawn for frame 382, so when we have done our track, we don’t want any transform to be applied on frame 382. For more information, see. 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. So, that concludes the second tutorial for Nuke’s PlanarTracker. 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). 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. I will also add a small amount of motion blur to the CornerPin for effect. The way they work is that each track layer will hold out the track layers below it. Licensing Back Installing the FLU Installing Licenses Server Admin. For our setup, we are going to select Mask Inverted Alpha. We open up the PlanarTracker node properties and set the Additional Input mask to Mask Inverted Alpha. Now, it looks like the PlanarTracker has done a reasonable job, but it’s not quite spot on, and we want to fix that. 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. Often the real screen, or the area of set that needs to be extended, may have been filmed with a green screen in place. Adjust consistency to prevent poor tracks in complex sequences. This means you can use the same powerful workflows with both trackers and can always choose the one that is best suited for the job at hand. In this shot, we want to track the top section of this post here. 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. 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. NOTE:  Jitter smoothing is not generally suited to heavy smoothing. Clearly, we want to hold out the cable for our comp and we can actually use our existing track result to do that. 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. Notice that the shape outline is colored purple to indicate it is in a track layer and will be used to define a region. You can see that, this time, the track is perfect. For more information, see, You can then use the plane you’ve tracked to trace another shape on the same plane, or proceed to place an image on the plane. The tracker works differently than the Nuke tracker regarding the “Transform” part. So because our holdout layer is on top, our holdout shape will mask out the logo from the floor shape beneath it. Il Planar Tracker di NUKE STUDIO e NUKEX consente di monitorare le aree della vostra sequenza. Notice the planar surface changes to a cyan color when it has a keyframe. You can adjust the indicator’s position by dragging it in the Viewer or by copying and pasting coordinates from other controls. While it’s tracking, let me tell you more about the PlanarTracker. 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. We now connect the PlanarTracker node’s Mask input to the Expression node, and we’re now ready to track. The first is the center planar surface button, which locks the Viewer to the center of the surface. Scrubbing through the timeline, we can see the track is slipping more and more as the track goes on. We can also create whole new track layers, ready for drawing and tracking. Let’s put this track on a loop so we can see exactly what's happening. Sets what mask or an alpha from another source you intend to include, for example, if you have the results of a chroma keying that you want to use with your primary mask: • Source Alpha - use the alpha channel of the source footage to define the plane to track. In this tutorial, I am going to demonstrate how to correct tracks when they drift. • This export option is always baked out in order for the transform to work correctly. Click to set the current frame as the reference frame for the planar surface. The easiest way to do this is to select the new track layer from the layer selected, and then just start drawing. 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. To fix this, we are going to create a holdout for the cable. The next evolution of Mocha. • Mask Inverted Luminance - use the inverted luminance of the mask input to define the plane to track. So we'll start by adding our planar tracker.…So we'll select our read node,…go and hit Tab, and select planar tracker,…holding down the Shift key so that it…does a branch connect, like that,…which is what I was looking for.…We'll hook our viewer up to my planar tracker.…Make sure I'm on frame one.…And here is the super secret trick.…Notice that the motion is to the right, kay?…So it's panning to the right.… This means you get a much more stable and accurate track compared to traditional 2D pattern trackers. Here it’s difficult to draw a shape in the first frame that will still exist in the last frame. Sets the threshold for smooth track generation. This does not need to be perfect, it just needs to be on the floor somewhere. The PlanarTracker follows flat surfaces where most points on the surface lie in the same plane. But instead of using mocha Pro, you can also use MochaImport+ with the planar track So that track looks pretty good. NOTE:  Each of the exports also has a bake option which copies the values of the keyframes out, instead of creating expression links. We can see that the track is slightly better for that point, however, we want better tools to help us diagnose when our track is going wrong and then to make corrections a lot easier. I think this is exactly what we want. Displays the coordinates of the outputBottomRight indicator in the Viewer. • planar-track this shape (fwd) - Select this to track your shape while the track is played forwards. 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. Drawing Roto shapes for tracking on green screens can sometimes be tricky, especially if there are lots of things occluding the screen. The furthest away object we want to track is in the bottom-most layer, and, in our case, our boat layer. 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. We can also use the grid to help us line up our surface. NUKE Planar Tracker Tutorial, The Foundry, Planar Tracker: NUKE tutorial by Escape Studios, NUKE STUDIO and NUKEX’s Planar Tracker, NUKE Planar, NUKE Planar Tracker, NUKE, The Foundry NUKE Planar Tracker, The Foundry NUKE Planar, The Foundry NUKE, NUKE STUDIO, NUKEX. Here, I’m reigning in the surface, which tells the PlanarTracker to care only about the transform relative to the floor and not the entire scene. - browse to the previous and next keyframe. • Mask Alpha - use the mask input alpha channel to define the plane to track. A rigid surface, like a wall or a side of an object, are good planes to track. Visual effects dominate at the box office, and Nuke is the compositing software that is used at high-end studios to create those mind-blowing effects. 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. We then set the Mask input to our final Crop node, and from this we can start tracking. Hold out mats can be used with a planar tracker so it'll ignore obstructions. 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. Then scrub in the timeline to make sure the results stick as they should. For the most part both of them have planar tracking … You can adjust the indicator’s position by dragging it in the Viewer or by copying and pasting coordinates from other controls. NukeX 6.3 Planar Tracker Tutorial: Rig Removal and Hold-Out Layers from The Foundry on Vimeo. FaceTracker is a Nuke node for facial tracking designed to work with models built with FaceBuilder. PlanarTracker is a powerful tool for tracking surfaces that lie on a plane in your source footage. It’s also used to define where to place images in the scene. Sets the number of features you want to track in each frame - ideally you should use more than 100 tracks per frame. Better still, we are going to track the cable and use the track as our holdout. 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. It’s important to note here that the behavior of the PlanarTracker’s additional input is different than that of the CameraTracker’s. 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. When enabled, you can adjust the plane using the four output indicators in the Viewer. If we want to, we can draw more shapes inside this layer, which will all contribute to the same track. We will start by drawing a shape to mask out the logo, being careful to draw it inside the Root layer. Click to clear all tracking information backward from the current frame. 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. This means that the transform at this point is extreme compared to the reference frame. I will start tracking and I will show you what I mean. Warped surface tracking and roto that sticks. Specifies plane transformation from the reference frame to the current frame. Hello, I’m Dan Ring and welcome to the third tutorial on Nuke’s new PlanarTracker. Click to set the planar surface to the bounds of the input image. 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. To be specific, they are keyed in the extra matrix knob for the layer. I will rename this layer post. I will also rename this layer boat. Now, we add it to its own track layer by selecting it and right-clicking and choosing planar-track this shape. Now let’s click the track to end button and watch it go. 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. • planar-track this shape - Select this to convert the roto shape into a track object that doesn't contain any tracking data (if it's not already). Now let’s try something more difficult. 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. Visual effects dominate at the box office, and Nuke is the compositing software that is used at high-end studios to create those mind-blowing effects. When using layers, the important thing to remember is that the track shape in each layer will hold out all the track layers below. So let’s draw these areas in two. 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. For now, the most useful knob here is the planar track layer selector. We just need to tweak the roto shape on the cable a little bit. As soon as we have done that, our track should look much better. To do this, I need to define where in the image I want the logo to be placed and then export my track data. Again, we have used some extra nodes for cleanup. You can see as we make a correction the Stabilize re-snaps the transform back into place. That concludes our third PlanarTracker tutorial. This is a special type of menu that is used to define what is being tracked. As in the previous tutorial, we will select our Read node and export a CornerPin using the absolute mode. Straight away, we can see that the cable wipes out the track. For the tracking itself, almost everything is the same. This red color looks like the end of the track pushed this planar surface into an invalid state. - [Steve Wright] Hi this is Steve Wright welcoming you to this week's Nuke Nugget. Sets the node type to export the track data: • CornerPin2D (relative) - warp the image according to the relative transform between the current frame and the reference frame. Now we are free to move the corners to where we want to place our image. Track complex organic surfaces through occlusions and blur using Mocha’s intuitive layer-based interface. That’s already looking much better, but we're not done yet. Going back to our cable track shape, you can tighten it out a bit and use it as a mask. Displays the coordinates of the outputBottomLeft indicator in the Viewer. Planar vector tracker Nuke Software: Nuke Compositing Community and Resources; scripts, gizmos, plugins, tutorials Smoothing works best for removing low-amplitude jitter, usually introduced by noisy images. Planar Tracker: NUKE tutorial by Escape Studios. This will automatically connect the CornerPin and select the correct image format. You can use your tracking results to replace the tracked plane with another image for instance. The Foundry's NukeX Tutorials on Planar Tracker: Correcting Tracking Drift, by Dan Ring. What we are going to do here is simply track the floor and move our clean plate along with the track. the many ways that mocha Pro is the ideal assist utility for NUKE VFX pipelines . If we turn on the display tracks button, we can see why. 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 click the go to reference frame button, just in case we forgot where we started. When enabled, a track preview is displayed so you can tweak the tracking parameters before tracking. Colour Schemes Color Grading Color … 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. • TSR + Shear - translation, scaling, rotation, and shear (move as if cutting through the scene). But instead of using mocha Pro, you can also use MochaImport+ with the planar tracker that is integrated in NUKE. This concludes our first tutorial on the PlanarTracker. 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. Well, in some cases you can get away with it, particularly if the surface of the occluding object is small. I am going to draw a white border around the cable. To start, we need to assess the damage. Follow. I will rename this layer holdout. 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. We look at all these in detail in later tutorials. I have already created a custom Transform node here to warp the logo to where I want it in our reference frame. The Stabilize node applies the exact opposite transform to your footage, so it will make your footage look like it’s standing perfectly still. Displays the coordinates of the top right corner of the plane in the Viewer. You can quickly place new 2D elements on a. Efectos Visuales Tutoriales De Arte Alambre Animación Artículos 3d. • TS + Rotation - translation, scaling, and rotation. The important thing to remember is that planar tracking tracks regions as opposed to small image patches. Let’s start by creating our PlanarTracker. Browse more videos. Our Tracker uses feature-based tracking; it tries to find the best tracks that agree with the plane the user has drawn, and from those it derives a planar track. You can quickly place new 2D elements on a However, it is difficult if you want to track one specific corner. 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. Adjusting this value can be useful in preventing poor tracks in complex sequences. NukeX 6.3 Planar Tracker Tutorial: Tracking with Chroma-Keys from The Foundry on Vimeo. Saved from youtube.com. You can see the Roto shape moved with the correction. 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 also use your tracking results to replace the tracked plane with an image, or link to a GridWarp node to manually transform a warp or morph function. Ordinarily in Roto land, we can simply paint a couple of mask shapes over our first shape. Notice that only the blue sky and cloud regions are being tracked. 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. To solve this, we need to hold this logo out from the shot. To give the features on the boat a decent buffer zone, and I am going to rename the layer to cable. That Tracker is ready to use, but first let’s go over what happened. This displays what is called the planar surface, shown here in blue. In this tutorial, I’m going to demonstrate how you might do some rig removal, using planar tracking and a background plate. 6 years ago | 29 views. This is different from the way you may create a regular holdout in the Roto node. NOTE:  By default, when you create a PlanarTracker node a Roto node is connected to this input. Basically, in Nuke they can only output a CornerPin with exactly 4 points, and they map 1 track to each corner of the CornerPin. This usually happens on these kind of shots when the camera is moving into the scene. See, Use the Tracker controls in the Viewer to track your footage. In this case, absolute means the input image will be fit into the bounds of the planar surface. .. In this case, you can simply go to the new frame and click the set current frame to reference frame button. I am going to speed up tracking to save time. I first make sure my post layer is selected, and then I click the correct plane button. If we scrub through the shot, you can see the surface has turned red for those strange frames. 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. Click to move the playhead to the tracker's reference frame. This option locks down the image so that the tracked plane effectively doesn't move - can be very useful for applying drift corrections. Now let’s set the alpha component of the shape’s color to 0. When we are done, we can click the Track Forward button and watch it track to the end of the shot. Now, remember in the previous tutorial I mentioned the concept of a reference frame, internally the transforms and other frames are calculated relative to the reference frame. I’m going to start by demonstrating just how quick and easy it is to create a planar track, and then go into some of the basics of the PlanarTracker. Click to track backwards through a range of frames specified using the frame range control. Then, to create a track from within the Roto node, we simply right-click the shape and click planar-track this shape. This allows you to use the Tracker's transform functions to stabilize, reduce jitter, and so on. We connect that up, and we create our Merge node as usual. • CornerPin2D (stabilize) - applies the inverse transform of the track to stabilize the image. This means we don’t want to create an absolute CornerPin node, we actually want a relative CornerPin node. When enabled, detected features are locked to local corners. We actually have two tools to help us see and correct for drift. NukeX 6.3 PlanarTracker Tutorial: Tracking Multiple Layers from The Foundry on Vimeo. 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? Artist. MochaImport+ for NUKE simplifies using the tracking software mocha Pro with NUKE. I’m going to rename the layer floor. High values spread features at even distances over the image. 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. For example, because our cable layer is above our boat layer, the boat shape will have the cable shape removed from it. I will also show you how to use additional track layers to create holdouts for tracks. Let’s do that now. This means anything we put in the layer will be affected by the track. Click to track forward through a range of frames specified using the frame range control. So, now let’s look at the alpha channel of our Roto node. All we need to do is go to our reference frame and adjust our planar surface (correct plane). This is the exact opposite of what would normally happen.
