The filter image represents the shape and size of the camera aperture used to shoot the input footage. How you create the filter image is up to you. By default, the blur effect is limited to the non-black areas of the mask. By default, the merge is limited to the non-black areas of the mask. Be careful to only blur by the minimum amount needed in these areas. By default, this menu is set to rgba.alpha. This is compatible with depth maps generated by Nuke and RenderMan. • Connect a mask to the mask input of the ZDefocus node. • far = -1 - Near plane = 0, far plane = -1. Dissolves between the original image at 0 and the full blur effect at 1. 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. 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. PxF_Bandpass 2.0.3: Extract detail from an image by subtracting the original image from a blur … Unpremult the blurred hand. 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. There is now the options to use Shape Blur or Global Blur starting from Nuke 7.0. • To use the same channels from the filter input as the image input (that is, whatever channels is set to), check use input channels. To better see the effect of your changes, you can also set output to focal plane setup. The blur effect is only applied to these channels. • Adjust inner brightness to control the brightness of the inner polygon, where 0 is equal to black and 1 to white. If you would like to download the gizmo, come and visit my website www.mark-spindler.com. Jan 13, 2017 - This is a short tutorial on my Position to Mask gizmo for Nuke. The reason for this is that the build-in glows are made up of a single blur that is added back over the top. If there is a lot of motion blur for the subject matter, I recommend using it as it can save time with proper planning. # make a node nuke. 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 View fullsize. The mask should properly adjust for image resolution and pixel aspect. • Make sure there is a mask channel in the ZDefocus node’s image input and nothing is connected to the mask input. This is like focal plane setup, but displays depth-of-field (DOF) information after the depth has been divided into layers. You can use catadioptric size to adjust the size of the catadioptric hole in the filter. This means you can have up to 256 layers behind the focal plane, and up to 256 in front of it as well. The Foundry Visionmongers Limited is registered in England and Wales. 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 […] 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. 4. • If you want to simulate catadioptric lenses, check catadioptric. Adds blur to an image or matte using box, triangle, quadratic, or gaussian filter algorithms. X_Denoise is a noise reduction gizmo that can be used to repair damaged or compressed footage. SPOT REMOVER SpotRemover works similar to MarkerRemoval. Menu Icons. Adjusting the Shape of Out-of-Focus Highlights. Setting size to 1 allows you to use the values in the depth map as the blur size directly. Often seen as interchangeable operations, this video shows when a defocus should be used instead of a blur. 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). NOTE:  When using filters that employ sharpening, such as Rifman and Lanczos, you may see a haloing effect. You can also create this node by pressing B on the Node Graph. If necessary, enhance the highlights to make lens shape effects more visible. Copies the mask input to the predefined mask.a channel. See Using a Predefined Disc Image. (check all that apply). • Use inner feather to add outward or inward feathering around the inner polygon. 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. 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. The default, gaussian, produces the smoothest blur, but takes longer to render. If you set this to something other than all or none, you can use the checkboxes on the right to select individual channels. An extremely powerful feature of NUKE is being able to mask almost any node by the mask input on the side. This allows you more control over the highlights than gamma correction; however, gamma correction may bring out some of the highlights better. Using ZDefocus to simulate a more narrow depth of field. See Enhancing the Out-of-Focus Highlights. 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. 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. Why wasn't this helpful? Note that if depth of field is set to 0, nothing is displayed in green. Mar 5, 2015 - This is a short tutorial on my Position to Mask gizmo for Nuke. nodes. See Using a Custom Filter Image. The fringe check box is used to blur the edges of the mask. This can be useful, for example, if you want to add color fringing to your out-of-focus highlights to simulate chromatic aberration. The advanced retiming and warping toolsets in Nuke Studio and NukeX take the headache out of shot retiming, clean-up, replacement and augmentation tasks. This video shows the power and steps to use this crucial… 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. If necessary, check clamp image filter to correct this problem. 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 : This allows it to preserve the ordering of objects in the image. By default, the blur is limited to the non-black areas of this channel. 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. 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). Note that the filter image can be a color image. Contrast is then selectively increased along these edges using this mask — leaving behind a sharper final image. 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. Has ability to use a mask or ramp to simulate DOF. • depth - The Z value in the depth channel is the distance between the camera and whatever is in the image at that pixel. • far = 1 - Near plane = 0, far plane = 1. Thanks for taking time to give us feedback. This is the default value. 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 … This means a gamma lookup curve of 2.2 is applied before blurring and then reversed for the final output. 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. If you cannot see the mask input, ensure that the mask control is disabled or set to none. • far = 0 - The Z value in the depth channel is equal to 1/distance. • Use a predefined bladed image (polygon) as the filter image. In this case, ZDefocus uses the entire format area, allowing you to offset the filter image within the format. 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. When using catadioptric lenses, the defocused areas of the image are annular, producing donut-shaped bokeh. It may be difficult to see if HD isn’t on but hopefully I explained well enough to compensate for SD viewing. 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). 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. Our non-commercial… Regular edge detect method will apply smear evenly all the way around." Note that this image also needs to contain a depth map channel. (Fixed issue qith mask input) All sliders have been normalized, so … This is the same as depth, but the distances are negative to start with. A value of 0.5 produces no feathering. The sharpening process works by utilizing a slightly blurred version of the original image. If you would like to download the gizmo, come and visit my website www.mark-spindler.com. • format - the filter input’s format. When disabled, the effect is applied to the entire mask. 4. Learning about defocus in Nuke. Adds blur to an image or matte using box, triangle, quadratic, or gaussian filter algorithms. To widen the area that is entirely in focus, increase, To apply a small amount of blur to the in-focus region, make sure. Disabling this checkbox is the same as setting the channel to none. This allows you to simulate depth-of-field (DOF) blurring. An optional image to use as a mask. 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. This way, you can use the mask input again downstream. Adjust the shape of any out-of-focus highlights. GRAIN Added functionality to Nuke's default grain node. Want to learn NUKE for free? The values are expected to decrease from large positive values close to the camera to zero at infinity. 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. Mask Input. Press command-F quite a few times to reapply the small 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. Creating Lens Flares in Nuke ... At the time, I thought a blur and defocus were the same thing. Enter quick mask by pressing Q. 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. By default, the filter effect is limited to the non-black areas of this channel. Motion Blur/Time Blur. Mask Inputs. The image is scaled down so the blur filter is no larger than this number, and then scaled up with linear interpolation after filtering. Note:  Box blur is the fastest to render, whereas Gaussian blur is the smoothest. This is a new addition in NUKE 7, replacing in essence the convolve and defocus tools in earlier versions. • Set the filter channel dropdown menu to the channel you want to use. When enabled, only apply the effect to the edge of the mask. 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. In other words, each layer is blurred by the same amount as in the direct mode. Focal point widget near the cars in the distance. The ZDefocus node blurs the image according to a depth map channel. If you have any thoughts on how we can improve our learning content, please email the Documentation team using the button below. The channel to use as a mask. For maximum processing speed, you may want to keep this value as low as possible. ... To mask the blur … No defocus or blur … • green - Inside DOF (in focus). Exit quick mask by pressing Q again. This looks wrong, as it suggests that those edge pixels are floating somewhere between the objects. Episode 01 is all about the BLUR node. (Use v5.3 for older versions of Nuke.) - Most nodes have a mask input that should behave like the 'side' input on Nuke nodes. You can also create this node by pressing B … Home About Tutorials. 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). 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; Ok, here we go, another Keying Tip, which I have to use sometimes to enhance Edges. 3. • -depth - The Z value in the depth channel is -distance in front of the camera. Join Steve Wright for an in-depth discussion in this video, Roto masking examples, part of Nuke Essential Training (2014). Completely redone for Nuke 12. Create a ZDefocus node and connect it to your script. To focus on a specific area, you can left-click on desired point on image, or play around with Blur Focal Distance slider. If necessary, you can also increase layer curve to concentrate the layers around the focal plane. +STARTLINE} addUserKnob {7 dilate_mask l "Dilate Mask" R 0 30} dilate_mask 2.8 ASPECTMASK Applies an aspect mask over the image. post_blur 5.5: addUserKnob {26 ""} addUserKnob {26 Masking} addUserKnob {6 xor_edge_detect l "Use XOR edge detect method?" The default, gaussian, produces the smoothest blur, but takes longer to render. Enables the associated mask channel to the right. Blur. Any highlights above the bloom threshold value are multiplied by the bloom gain value. Controls the trade off between faster processing time at lower values, and smoothness at higher values. If I would have done any research into this, it would have been very obvious that there's a huge difference. This avoids creating oversized bounding boxes that can take longer to compute. You can create a filter image using the Roto node (Draw > Roto) or the Flare node (Draw > Flare), for example. To get a glow with a hard edge and a soft falloff, you'll want to combine several glows with different blur sizes. You can adjust the black point of the mask for it, the mask thus becomes hard-edged. If you cannot see the mask input, open the node’s controls and make sure mask is set to none. This video demonstrates workflow for wire removal using the blur and grow technique, with roto and keyed masks. 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 … 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. The default value of 0 produces evenly spaced layers. Because of the high information density of this video, please feel free to pause or re-watch parts of the video. See Using a Predefined Bladed Image. 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. 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. Filipe Costa… When show image is enabled, this information is overlaid upon the input image. - New nodes: PxF_Grain, PxF_Line, PxF_MergeWrap - Various bug fixes and improvements.
