NOTE:  When using filters that employ sharpening, such as Rifman and Lanczos, you may see a haloing effect. ZDefocus now displays depth-of-field (DOF) info in the rgb channels: • red - Less than DOF (in front of the area that’s in focus). You can also create this node by pressing B on the Node Graph. This allows it to preserve the ordering of objects in the image. The Best Nuke Compositing Tutorials. There are many ways to fill in missing or unwanted sections of an image with content that matches the surrounding pixels. To better see the effect of your changes, you can also set output to focal plane setup. Nuke 101- PART 1: Introduction Nuke 101- PART 2: Image Formats Nuke 101- PART 3: Color Nuke 101- PART 4: Color Management Nuke 101- PART 5: B-Side and B-Box Shuffle and Channel Management in Nuke Unleash The Node – Episode 01 – Blur – Nuke Compositing Tutorial Series • Adjust inner brightness to control the brightness of the inner polygon, where 0 is equal to black and 1 to white. A value of 0.5 produces no feathering. 0:00 Intro 1:09 Convolution 3:00 Filter Types & Falloff Treatment 5:20 Quality 5:56 Blurring & Denoising 13:54 Sharpen 16:22 Exponential Glow 20:26 Edge Mask 21:10 Directional Blur […] Edge Blur (The Foundry Nuke) This video tutorial aims to explain how blur edges of layers that have some kind of transparency (such as alpha channel or other composite mattes). This allows you more control over the highlights than gamma correction; however, gamma correction may bring out some of the highlights better. By default, the blur effect is limited to the non-black areas of the mask. This means you can have up to 256 layers behind the focal plane, and up to 256 in front of it as well. mix Our non-commercial… No defocus or blur … ... To mask the blur … • Connect a mask to the mask input of the ZDefocus node. Adds blur to an image or matte using box, triangle, quadratic, or gaussian filter algorithms. By default, the merge is limited to the non-black areas of the mask. See Using a Custom Filter Image. For maximum processing speed, you may want to keep this value as low as possible. If necessary, enhance the highlights to make lens shape effects more visible. After ZDefocus has processed all the layers, it blends them together from the back to the front of the image, with each new layer going over the top of the previous ones. When disabled, the effect is applied to the entire mask. By default, this menu is set to rgba.alpha. I’m loving these recent tutorials from Joe Raasch, and with this new addition, joe looks at creating a lens blur and bokeh effect in NUKE using the new zDefocus tool. If you would like to download the gizmo, come and visit my website www.mark-spindler.com. The filter image represents the shape and size of the camera aperture used to shoot the input footage. • If you want to simulate catadioptric lenses, check catadioptric. Using ZDefocus to simulate a more narrow depth of field. GRAIN Added functionality to Nuke's default grain node. Any layers with this Z depth value are left in focus. Note:  Box blur is the fastest to render, whereas Gaussian blur is the smoothest. • Set the filter channel dropdown menu to the channel you want to use. If I would have done any research into this, it would have been very obvious that there's a huge difference. In the example above you can that where the black t-shirt sleeve meets the arm, the colour of the skin has bled into the black of the t-shirt. • Use a predefined bladed image (polygon) as the filter image. If you have any thoughts on how we can improve our learning content, please email the Documentation team using the button below. • -direct - As with the direct mode, the Z value in the depth channel directly controls blur. You can adjust the black point of the mask for it, the mask thus becomes hard-edged. If you have set math to direct, the size is multiplied by the depth to give the blur size at that depth. Blur + Unpremult. In other words, each layer is blurred by the same amount as in the direct mode. This is compatible with depth maps generated by Maya. Focal point widget near the cars in the distance. If there is a lot of motion blur for the subject matter, I recommend using it as it can save time with proper planning. You can use catadioptric size to adjust the size of the catadioptric hole in the filter. Home About Tutorials. - Most nodes have a mask input that should behave like the 'side' input on Nuke nodes. Be careful to only blur by the minimum amount needed in these areas. See Enhancing the Out-of-Focus Highlights. This is a nice trick especially when dealing with lower quality material, like DSRL greenscreens, where Edges often tend get jaggy or you end up having black or white outlines. To visualize the layers, you can set output to layer setup. X_Denoise is a noise reduction gizmo that can be used to repair damaged or compressed footage. Learning about defocus in Nuke. You can also set a depth slice around the focus plane that is in focus (as described in step 4), but any other areas of the image are blurred according to the depth map. For example, if Z is 0.5, then the blur size is 0.5 times the value of the size control (unless this is bigger than maximum, in which case it is clamped to maximum). Blur. The maximum number of blur sizes that are used between 0 and maximum is 256. Adds blur to an image or matte using box, triangle, quadratic, or gaussian filter algorithms. • far = -0 - The Z value in the depth channel is equal to -1/distance. If necessary, you can also increase layer curve to concentrate the layers around the focal plane. You must restart Nuke for the change to take effect.The GPU processing requires certain NVIDIA GPUs and CUDA drivers. You can create a filter image using the Roto node (Draw > Roto) or the Flare node (Draw > Flare), for example. Press command-F quite a few times to reapply the small blur. This allows you to simulate the cat's eye effect, caused by vignetting inherent within some lens designs. If you cannot see the mask input, ensure that the mask control is disabled or set to none. Join Steve Wright for an in-depth discussion in this video, Roto masking examples, part of Nuke Essential Training (2014). To adjust the distribution of light inside the out-of-focus highlights: To make bokeh lens shape effects warmer and more visible, check, You can also make the lens shape effects more visible by enabling, If you don’t want to use the alpha channel as the matte, select the channel you want to use from the, To dissolve between the original image (at 0) and the full ZDefocus effect (at 1), adjust the. Often seen as interchangeable operations, this video shows when a defocus should be used instead of a blur. The default, gaussian, produces the smoothest blur, but takes longer to render. Create a ZDefocus node and connect it to your script. Enter quick mask by pressing Q. Ok, here we go, another Keying Tip, which I have to use sometimes to enhance Edges. Joshua Clos notes: “A quick tutorial for beginners showing how to comp depth of field and motion blur in Nuke using passes. • depth - The Z value in the depth channel is the distance between the camera and whatever is in the image at that pixel. This video shows the power and steps to use this crucial… This is the default value. Joshua Clos shows how to use NUKE to composite depth of field and 3D motion blur in the composite using render passes to save on render time. While most de-noisers try to work out which small pixels are susceptible to be noisy, the X_Denoise averages different frames in order to smooth the noise, making … The image is scaled down so the blur filter is no larger than this number, and then scaled up with linear interpolation after filtering. However, because the true image information isn't available in these regions, fill foreground can sometimes introduce undesirable artefacts by adding things which aren't there.If you see blurry artefacts in the foreground, rather than sharp edge artefacts, try disabling this control. You can: • Use a predefined disc shape as the filter image. One of the most common methods among Nuke artist is to first blur the image, and then unpremultiplying it (turning the soft alpha area solid), and then adding it underneath the original image using the mask as a holdout. Sets the radius within which pixels are compared to calculate the blur. • green - Inside DOF (in focus). Simulates realistic lens blurring. • far = 0 - The Z value in the depth channel is equal to 1/distance. (Use v5.3 for older versions of Nuke.) You can also create this node by pressing B … The reason for this is that the build-in glows are made up of a single blur that is added back over the top. Higher values widen the compare area, producing more blur. Optical Flow-based Motion Blur generates high-quality GPU-accelerated motion vectors, enabling you to add realistic blur to clips based on the movement of objects within them. • far = -1 - Near plane = 0, far plane = -1. In this case, ZDefocus only uses the bounding box area, and the center of the filter is the center of the bounding box. • Use your own custom image in the filter input as the filter image. - New nodes: PxF_Grain, PxF_Line, PxF_MergeWrap - Various bug fixes and improvements. Lastly but not related to AE, the in-house motion blur plugin that we must use (read: forced) suffer from memory leak which gobble up all the allocated RAM for AE. When using catadioptric lenses, the defocused areas of the image are annular, producing donut-shaped bokeh. TIP:  The fill foreground control, enabled by default, attempts to compensate for missing information by filling regions in the foreground which are revealed when the foreground goes out of focus. In order to defocus the image, ZDefocus splits the image up into layers, each of which is assigned the same depth value everywhere and processed with a single blur size. So my odd pipeline involves Nuke as my first step in compositing my FX works and transferring it to AE once the cut are approved by the director for use by the compositing team. Regular edge detect method will apply smear evenly all the way around." The default value of 0 produces evenly spaced layers. Has ability to use a mask or ramp to simulate DOF. Completely redone for Nuke 12. SPOT REMOVER SpotRemover works similar to MarkerRemoval. At first, the mask input appears as triangle on the right side of the node, but when you drag it, it turns into an arrow labeled mask. The values are expected to decrease from large positive values close to the camera to zero at infinity. An optional image to use as a mask. The blur effect is only applied to these channels. This can be useful, for example, if you want to add color fringing to your out-of-focus highlights to simulate chromatic aberration. The mask should properly adjust for image resolution and pixel aspect. If you set this to something other than all or none, you can use the checkboxes on the right to select individual channels. In this case, ZDefocus uses the entire format area, allowing you to offset the filter image within the format. Note: Step 2 combines the three images using a "mask overlay," which is when image information from the layer above the unsharp mask passes through and replaces the layer … Another approach is to utilize the Time Blur node to apply the motion blur … Blur #assign to a variable b = nuke. The Foundry Visionmongers Limited is registered in England and Wales. All relevant nodes have masks inputs that turn on automatically when in-use, just like the mask input of any standard Nuke node. If your matte needs to move, then you need to apply your movement after the fractal blur, otherwise the texture of the blur will not lock to it and will appear to slide relative to the mask. As the clip in the image input is blurred, any highlights in the clip bloom in the shape of the filter image, creating a bokeh effect. Choose Filter > Blur > Gaussian Blur and use a small radius (0.5px etc). The advanced retiming and warping toolsets in Nuke Studio and NukeX take the headache out of shot retiming, clean-up, replacement and augmentation tasks. I’ve added a mask input to my Nuke node which allows you to isolate these types of areas and leave them unaffected. Episode 01 is all about the BLUR node. When you select the invert check box, the mask channel will be inverted and now merge will be limited to the non-white areas of the mask. Mar 5, 2015 - This is a short tutorial on my Position to Mask gizmo for Nuke. Note that if depth of field is set to 0, nothing is displayed in green. To focus on a specific area, you can left-click on desired point on image, or play around with Blur Focal Distance slider. Press Shift+S to open the Preferences dialog, make sure you’re viewing the Preferences tab, and set GPU Device to the device you want to use. Mask Input. Note that the depth map should not be anti-aliased. Creating Lens Flares in Nuke ... At the time, I thought a blur and defocus were the same thing. This is a new addition in NUKE 7, replacing in essence the convolve and defocus tools in earlier versions. ASPECTMASK Applies an aspect mask over the image. PxF_Bandpass 2.0.3: Extract detail from an image by subtracting the original image from a blur … In older Nuke scripts with legacy resize mode enabled, use the filter bounds dropdown to select whether you want to limit the filter image to: • shape - the filter input’s bounding box. By default, the filter effect is limited to the non-black areas of this channel. For more information on the minimum requirements, please refer to the Nuke Release Notes available in Help > Release Notes.If you are using a render license of Nuke, you need to add --gpu on the command line. This allows you to simulate depth-of-field (DOF) blurring. This avoids creating oversized bounding boxes that can take longer to compute. Injecting the mask allows you to use the same mask further downstream. Multiply the hand with the shrunk copy of the mask. Motion Blur/Time Blur. Note that the filter image can be a color image. Filipe Costa… Note that this image also needs to contain a depth map channel. Dissolves between the original image at 0 and the full blur effect at 1. The output between the GPU and CPU is identical, but using the GPU can significantly improve processing performance.You can select the GPU to use in the preferences. Why wasn't this helpful? Controls the trade off between faster processing time at lower values, and smoothness at higher values. See Using a Predefined Disc Image. post_blur 5.5: addUserKnob {26 ""} addUserKnob {26 Masking} addUserKnob {6 xor_edge_detect l "Use XOR edge detect method?" This is the same as depth, but the distances are negative to start with. The channel to use as a mask. Thanks for taking time to give us feedback. • direct - The Z value in the depth channel directly controls blur. nodes. This automatically updates the focal point coordinates in the ZDefocus properties and sets the focus plane control to the Z depth value at those coordinates. When show image is enabled, this information is overlaid upon the input image. The fringe check box is used to blur the edges of the mask. Highlights below the bloom threshold are not affected. (check all that apply). 4. Disabling this checkbox is the same as setting the channel to none. This is like focal plane setup, but displays depth-of-field (DOF) information after the depth has been divided into layers. Note that you don’t necessarily need to crop the filter image to a smaller size, as fast Fourier transforms are used to speed up convolutions with large filter images. To get a glow with a hard edge and a soft falloff, you'll want to combine several glows with different blur sizes. Contrast is then selectively increased along these edges using this mask — leaving behind a sharper final image. The injected mask can be further used downstream in the process tree. NOTE:  Loading scripts from pre-Nuke 8.0v7 enables the legacy resize mode checkbox automatically, for backward compatibilty, and uses the filter bounds dropdown to determine how images used in filtering are resized.Adding new ZDefocus nodes hides the legacy resize mode checkbox and allows you to use the image filter dropdown to give you more flexibility when calculating blur.See Using a Custom Filter Image for more information. Any highlights above the bloom threshold value are multiplied by the bloom gain value. Exit quick mask by pressing Q again. • format - the filter input’s format. If you would like to download the gizmo, come and visit my website www.mark-spindler.com. As the clip in the image input is blurred, any out-of-focus highlights (bokeh) in the clip assume the shape of the filter image (of the filter type selected). Adjusting the Shape of Out-of-Focus Highlights. NOTE:  Loading scripts from pre-Nuke 8.0v7 enables the legacy resize mode checkbox automatically, for backward compatibilty, and uses the filter bounds dropdown to determine how images used in filtering are resized.Adding new ZDefocus nodes hides the legacy resize mode checkbox and allows you to use the image filter dropdown to give you more flexibility when calculating blur. Change to the gradient tool by pressing G. Draw along the axis you want the blur to follow, covering the length of the object. 3. If your depth channel and rgba channels exist in two different files, you can use a ShuffleCopy node to combine them. Here is the GitHub link for the node – just select the text, copy it then, then paste it into Nuke… Want to learn NUKE for free? An extremely powerful feature of NUKE is being able to mask almost any node by the mask input on the side. If it is, pixels along an edge between two objects can be assigned a depth that is in-between the depth of the front object and back objects. If you want to use your own filter image (rather than the predefined. toNode ('Blur1') ... Hit v to get into 'make a mask' node (its also on the side of the viewport, 3rd button, the bezier handle icon) Click down points, click-drag to set a point and drag it out to make smooth; It's especially useful when you need to simulate a very 'out-of-focus' background. Adjust the shape of any out-of-focus highlights. Unpremult the blurred hand. THE NUKE NODE . This is compatible with depth maps generated by Nuke and RenderMan. Enables the associated mask channel to the right. If you cannot see the mask input, open the node’s controls and make sure mask is set to none. • To use the same channels from the filter input as the image input (that is, whatever channels is set to), check use input channels. See Adjusting the Shape of Out-of-Focus Highlights. This means a gamma lookup curve of 2.2 is applied before blurring and then reversed for the final output. If you can't find what you're looking for or you have a workflow question, please try Foundry Support. • Make sure there is a mask channel in the ZDefocus node’s image input and nothing is connected to the mask input. This way, you can use the mask input again downstream. # make a node nuke. ...
