nuke blur mask

By default, this menu is set to rgba.alpha. This is compatible with depth maps generated by Nuke and RenderMan. PxF_Bandpass 2.0.3: Extract detail from an image by subtracting the original image from a blur … To visualize the layers, you can set output to layer setup. 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). 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 mix Controls the trade off between faster processing time at lower values, and smoothness at higher values. 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. To better see the effect of your changes, you can also set output to focal plane setup. 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. 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). • Connect a mask to the mask input of the ZDefocus node. Our non-commercial… This can be useful, for example, if you want to add color fringing to your out-of-focus highlights to simulate chromatic aberration. Enter quick mask by pressing Q. To get a glow with a hard edge and a soft falloff, you'll want to combine several glows with different blur sizes. 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). 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; Creating Lens Flares in Nuke ... At the time, I thought a blur and defocus were the same thing. Before downloading Fast Download Nuke Smart Vector Motion Blur Viral, you can preview any Video by mouse over the PLAY VIDEO button and click Play or Click DOWNLOAD button to download hd quality Mp3, Mp4 and 3gp files.Fast Download Nuke Smart Vector Motion Blur Viral : If you cannot see the mask input, open the node’s controls and make sure mask is set to none. If your depth channel and rgba channels exist in two different files, you can use a ShuffleCopy node to combine them. NOTE:  When using filters that employ sharpening, such as Rifman and Lanczos, you may see a haloing effect. t "XOR edge detect will isolate edge mask to areas that are blurred. Note that if depth of field is set to 0, nothing is displayed in green. This looks wrong, as it suggests that those edge pixels are floating somewhere between the objects. • If you want to simulate catadioptric lenses, check catadioptric. Thanks for taking time to give us feedback. • To use the same channels from the filter input as the image input (that is, whatever channels is set to), check use input channels. Adjusting the Shape of Out-of-Focus Highlights. The advanced retiming and warping toolsets in Nuke Studio and NukeX take the headache out of shot retiming, clean-up, replacement and augmentation tasks. By default, the blur effect is limited to the non-black areas of the mask. This allows it to preserve the ordering of objects in the image. 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. If necessary, check clamp image filter to correct this problem. 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. Regular edge detect method will apply smear evenly all the way around." By default, the merge is limited to the non-black areas of the mask. The channel to use as a mask. Jan 13, 2017 - This is a short tutorial on my Position to Mask gizmo for Nuke. If I would have done any research into this, it would have been very obvious that there's a huge difference. You can create a filter image using the Roto node (Draw > Roto) or the Flare node (Draw > Flare), for example. When using catadioptric lenses, the defocused areas of the image are annular, producing donut-shaped bokeh. TIP:  You can check Use GPU if available in the ZDefocus controls to have the node run on the graphics processing unit (GPU) rather than the central processing unit (CPU). In this case, ZDefocus only uses the bounding box area, and the center of the filter is the center of the bounding box. The default value of 0 produces evenly spaced layers. For maximum processing speed, you may want to keep this value as low as possible. (Fixed issue qith mask input) All sliders have been normalized, so … X_Denoise is a noise reduction gizmo that can be used to repair damaged or compressed footage. View fullsize. This allows you to simulate the cat's eye effect, caused by vignetting inherent within some lens designs. 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 … Why wasn't this helpful? Want to learn NUKE for free? Blur. Episode 01 is all about the BLUR node. This means you can have up to 256 layers behind the focal plane, and up to 256 in front of it as well. Exit quick mask by pressing Q again. The maximum number of blur sizes that are used between 0 and maximum is 256. Multiply the hand with the shrunk copy of the mask. This is like focal plane setup, but displays depth-of-field (DOF) information after the depth has been divided into layers. +STARTLINE} addUserKnob {7 dilate_mask l "Dilate Mask" R 0 30} dilate_mask 2.8 You can use catadioptric size to adjust the size of the catadioptric hole in the filter. nodes. This means a gamma lookup curve of 2.2 is applied before blurring and then reversed for the final output. • blue - Greater than DOF (behind the area that’s in focus). This is then subtracted away from the original to detect the presence of edges, creating the unsharp mask(effectively a high-pass filter). However, in this mode, the layers are interpreted as being in the opposite order, so a higher depth value places a layer in front of another rather than behind it. Simulates realistic lens blurring. Blur #assign to a variable b = nuke. By default, the filter effect is limited to the non-black areas of this channel. • Use your own custom image in the filter input as the filter image. This way, you can use the mask input again downstream. No defocus or blur … There is now the options to use Shape Blur or Global Blur starting from Nuke 7.0. If you can't find what you're looking for or you have a workflow question, please try Foundry Support. • direct - The Z value in the depth channel directly controls blur. (Use v5.3 for older versions of Nuke.) The filter image represents the shape and size of the camera aperture used to shoot the input footage. If you set this to something other than all or none, you can use the checkboxes on the right to select individual channels. • Use inner feather to add outward or inward feathering around the inner polygon. Learning about defocus in Nuke. It does the same function of the Nuke Denoise, but using a different algorithm that can sometimes provide better results.. An extremely powerful feature of NUKE is being able to mask almost any node by the mask input on the side. The fringe check box is used to blur the edges of the mask. Note:  Box blur is the fastest to render, whereas Gaussian blur is the smoothest. You can adjust the black point of the mask for it, the mask thus becomes hard-edged. • green - Inside DOF (in focus). # make a node nuke. 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. There are many ways to fill in missing or unwanted sections of an image with content that matches the surrounding pixels. Adjust the shape of any out-of-focus highlights. Sets the radius within which pixels are compared to calculate the blur. Note that the filter image can be a color image. Be careful to only blur by the minimum amount needed in these areas. See Enhancing the Out-of-Focus Highlights. - Most nodes have a mask input that should behave like the 'side' input on Nuke nodes. Mask Input. ... Set the near and far plane of the fog in the depth mask … GRAIN Added functionality to Nuke's default grain node. If you want to use your own filter image (rather than the predefined. This avoids creating oversized bounding boxes that can take longer to compute. ASPECTMASK Applies an aspect mask over the image. (check all that apply). This video shows the power and steps to use this crucial… The default, gaussian, produces the smoothest blur, but takes longer to render. Enables the associated mask channel to the right. If you have any thoughts on how we can improve our learning content, please email the Documentation team using the button below. If necessary, you can also increase layer curve to concentrate the layers around the focal plane. The ZDefocus node blurs the image according to a depth map channel. A value of 0.5 produces no feathering. Another approach is to utilize the Time Blur node to apply the motion blur … See Using a Predefined Bladed Image. 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 … You can also create this node by pressing B … 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. See Using a Predefined Disc Image. Using ZDefocus to simulate a more narrow depth of field. When enabled, only apply the effect to the edge of the mask. THE NUKE NODE . When disabled, the effect is applied to the entire mask. - New nodes: PxF_Grain, PxF_Line, PxF_MergeWrap - Various bug fixes and improvements. Menu Icons. Has ability to use a mask or ramp to simulate DOF. 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. • far = -1 - Near plane = 0, far plane = -1. 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 […] All relevant nodes have masks inputs that turn on automatically when in-use, just like the mask input of any standard Nuke node. SPOT REMOVER SpotRemover works similar to MarkerRemoval. 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. 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. 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. ... To mask the 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). 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. Copies the mask input to the predefined mask.a channel. In this case, ZDefocus only uses the bounding box area, and the center of the filter is the center of the bounding box. This video demonstrates workflow for wire removal using the blur and grow technique, with roto and keyed masks. Create a ZDefocus node and connect it to your script. 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. 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. 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. Highlights below the bloom threshold are not affected. This is the same as depth, but the distances are negative to start with. If necessary, enhance the highlights to make lens shape effects more visible. The blur effect is only applied to these channels. • Set the filter channel dropdown menu to the channel you want to use. • Use a predefined bladed image (polygon) as the filter image. Any highlights above the bloom threshold value are multiplied by the bloom gain value. To focus on a specific area, you can left-click on desired point on image, or play around with Blur Focal Distance slider. • Make sure there is a mask channel in the ZDefocus node’s image input and nothing is connected to the mask input. See Using a Custom Filter Image. If you cannot see the mask input, ensure that the mask control is disabled or set to none. Blur the multiplied result as much as to cover all the motion-blurred area of the original footage (you can adjust it more precisely later, looking at the final result) 5. 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. In this case, ZDefocus uses the entire format area, allowing you to offset the filter image within the format. The default, gaussian, produces the smoothest blur, but takes longer to render. 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. You must restart Nuke for the change to take effect.The GPU processing requires certain NVIDIA GPUs and CUDA drivers. 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. The blur value is calculated for image pixels by examining their neighbors within the constraints of the size control (in pixels), and applying the selected algorithms. I’ve added a mask input to my Nuke node which allows you to isolate these types of areas and leave them unaffected. • Adjust inner brightness to control the brightness of the inner polygon, where 0 is equal to black and 1 to white. 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. Note that the depth map should not be anti-aliased. When enabled, the bounding box cannot grow past its incoming size. Press command-F quite a few times to reapply the small blur. With values larger than 0.5, your feather effect is outward and, respectively, if your values are smaller than 0.5, the feather effect is inward. This field only accepts integers larger than 1. • Adjust inner size to control the size of the inner polygon, as a percentage of the outer polygon. 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. • -direct - As with the direct mode, the Z value in the depth channel directly controls blur. Filipe Costa… This is compatible with depth maps generated by Maya. The sharpening process works by utilizing a slightly blurred version of the original image. An optional image to use as a mask. Ok, here we go, another Keying Tip, which I have to use sometimes to enhance Edges. If you have set math to direct, the size is multiplied by the depth to give the blur size at that depth. This tells ZDefocus to use the filter input rather than a predefined shape as the filter image. You may want to use it, for example, if your filter input is a roto shape with a small bounding box that doesn’t fill the entire format area. The reason for this is that the build-in glows are made up of a single blur that is added back over the top. 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. • far = -0 - The Z value in the depth channel is equal to -1/distance. Joshua Clos notes: “A quick tutorial for beginners showing how to comp depth of field and motion blur in Nuke using passes. The blur value is calculated for image pixels by examining their neighbors within the constraints of the size control (in pixels), and applying the selected algorithms. The injected mask can be further used downstream in the process tree. So let's start I build this tutorial based on the previous Unpremult the blurred hand. • far = 0 - The Z value in the depth channel is equal to 1/distance. Mask Inputs. Dissolves between the original image at 0 and the full blur effect at 1. You can also create this node by pressing B on the Node Graph. Because of the high information density of this video, please feel free to pause or re-watch parts of the video. It's especially useful when you need to simulate a very 'out-of-focus' background. All tools are grouped in their own menu with custom menu icons for easy access. Motion Blur/Time Blur. 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. This allows you to simulate depth-of-field (DOF) blurring. Home About Tutorials. This is compatible with depth maps generated by OpenGL. Focal point widget near the cars in the distance. 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. Adds blur to an image or matte using box, triangle, quadratic, or gaussian filter algorithms. This is the default value. To widen the area that is entirely in focus, increase, To apply a small amount of blur to the in-focus region, make sure. Contrast is then selectively increased along these edges using this mask — leaving behind a sharper final image. • far = 1 - Near plane = 0, far plane = 1. 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. See Adjusting the Shape of Out-of-Focus Highlights. • format - the filter input’s format. • depth - The Z value in the depth channel is the distance between the camera and whatever is in the image at that pixel. Inverts the use of the mask channel so that the filter effect is limited to the non-white areas of the mask. 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. Disabling this checkbox is the same as setting the channel to none. Mar 5, 2015 - This is a short tutorial on my Position to Mask gizmo for Nuke. Note that this image also needs to contain a depth map channel. Join Steve Wright for an in-depth discussion in this video, Roto masking examples, part of Nuke Essential Training (2014). This is a new addition in NUKE 7, replacing in essence the convolve and defocus tools in earlier versions. It may be difficult to see if HD isn’t on but hopefully I explained well enough to compensate for SD viewing.
