nuke planar tracker holdout

Software required: NUKE … In fact, the Roto node is essential for the PlanarTracker to work, so always try and keep them connected. ( Log Out /  Straight away, we can see that the cable wipes out the track. In this inverted space, you can actually see the window drifting away from the planar surface. So, now let’s look at the alpha channel of our Roto node. This unique workflow uses planar tracking analysis on “both eye views” to reduce manual offsets and tedious keyframe work on stereo 3D rotoscoping, tracking… Now, if we scrub along we can see that looks much better. Join Steve Wright for an in-depth discussion in this video, Planar Tracker workflow, part of Nuke Essential Training (2014). If we scrub through the shot, you can see the surface has turned red for those strange frames. 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. Roto shape ready for planar tracking. Learn how to remove rig and hold-out layers with the Planar Tracker in The Foundry Nuke 6. Nuke NukeX Nuke Studio. Currently I have the Studio version of Foundry NUKE but I am a bit curious about tracking capabilities of MOCHA PRO. For example, because our cable layer is above our boat layer, the boat shape will have the cable shape removed from it. Let’s put this track on a loop so we can see exactly what's happening. So we are nearly done, however, if we look at our output, you will see the logo is appearing over the cable. 04. 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. And why wouldn't I be able to use planar tracking for inputting a 3D element on a flat surface? 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. We are then going to open the PlanarTracker node’s properties and change the Additional Input knob. As I mentioned before, in the brief of the 2D project, I am required to do cleanup on my original plate. This also means our Roto shape needs to have been drawn at frame 382, which I have already made sure to do so. We actually have two tools to help us see and correct for drift. This is the exact opposite of what would normally happen. Input. This will automatically connect the CornerPin and select the correct image format. We just need to tweak the roto shape on the cable a little bit. Again, beginning at frame 382, and tracking to the beginning of the shot. Notice that only the blue sky and cloud regions are being tracked. 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. Hi, I’m Dan Ring and welcome to the fifth tutorial for Nuke’s new PlanarTracker. 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). Jan 27, 2014 - NUKE is a compositor utilizing a flexible node-based, native multichannel workflow with an integrated 3D compositing environment to create high-quality digital content. 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. 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. This is a special type of menu that is used to define what is being tracked. 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. 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. We can also create whole new track layers, ready for drawing and tracking. I think this is exactly what we want. The planar tracker recognizes this bubble and starts to track it (as long as the white bubble is within the your tracking polygon). Now, let’s close our display handles and set the track to look so we can see it better. 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. Click the link below to watch full tutorial : NUKEX 6.3 Planar Tracker Tutorial: Rig Removal & Hold-Out Layers. 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. 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. In particular, we are going to export a Stabilize node and connect it to the Viewer. We can also turn on display grid lines to help us line up the window perfectly. Also is MOCHA PRO worth investing, even though I have NUKE STUDIO. Change ), NUKEX 6.3 Planar Tracker Tutorial: Rig Removal & Hold-Out Layers, How to create hologram disc, as seen in “Tron Legacy” using Cinema 4D, Mac OSX. We can tweak it in, and it’s good to go. This means that the transform at this point is extreme compared to the reference frame. 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 is a diagnostic plane you can use to spot when tracks start to fail and how to correct them. I am going to draw a white border around the cable. Stereo 3D planar tracking, masking, and object removal workflow. We will start from the beginning and work our way to the end. Let’s do that now. Nuke X also comes with a Planar tracker. We will get rid of the drawing handles and see how that track went. The PlanarTrackerLayer is also the place where the results of the track are saved to. But instead of using mocha Pro, you can also use MochaImport+ with the planar tracker… Inputs and Controls. 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. 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. I will also close all of the properties panels. The easiest way to do this is to select the new track layer from the layer selected, and then just start drawing. 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. Now, what I would like to do is insert this Nuke logo into our post track. 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. I will rename this layer holdout. We connect that up, and we create our Merge node as usual. NOTE: This footage has been used for self-educational purposes only. 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. To see how the track went, we can display and move our planar surface on the reference frame, and then scrub through the timeline. Now let’s click the track to end button and watch it go. Scrubbing through the timeline, we can see the track is slipping more and more as the track goes on. In this tutorial I’m going to show you how to use additional inputs in planar tracking. To fix this, we are going to create a holdout for the cable. Learn how to remove rig and hold-out layers with the Planar Tracker in The Foundry Nuke 6. Posted by copiwp on December 20, 2012. This concludes our first tutorial on the PlanarTracker. Notice the planar surface changes to a cyan color when it has a keyframe. Complete LED video wall solution with advanced video wall processing, off-board electronics, front serviceable cabinets and outstanding image quality available in 0.7, 0.9, 1.2, 1.5 and 1.8mm pixel pitches The Planar Tracker is also a very helpful addition to the Roto toolkit in Nuke. 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. 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. What we are going to do here is simply track the floor and move our clean plate along with the track. It’s also gone a bit wild here in the Viewer. The PlanarTracker follows flat surfaces where most points on the surface lie in the same plane. Instead, we’ll go back to our floor track and go to our reference frame. Tracking with PlanarTracker. 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. 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. Then, to create a track from within the Roto node, we simply right-click the shape and click planar-track this shape. For the tracking itself, almost everything is the same. 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. Now let’s try something more difficult. In this shot, we have a camera dolly track in the frame that we would like to remove. 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. Sorry if this post is confusing.
