Keying 10. * don’t even think about doing roto with a mouse! applying motion blur node, or Motion Blur 2d by tracking the movements) and create the motion blur on the mattes, however, an easy solution would be using “TimeBlur” which is very similar to the motion blur settings in Silhouette. There  are so many tricks you can work out to deal with this of course (e.g. • forward - the forward method is slower, but it gives you a more accurate result, especially in cases where the vectors don't cover the whole frame. It takes a little time getting used to, but it gives you motion blur based on the shutter speed. THE SOLUTION To get around this we can break up the blurred areas by generating noise and multiplying it against the matte first. Next we blur the image and then unpremultiply it. If there is a lot of motion blur for the subject matter, I recommend using it as it can save time with proper planning. When using several of these nodes in a row, the motion blur is concatenated, and the last transform in the chain defines the motion blur applied. sorry I just saw this – how is Silhouette treating you these days? It analyzes the source sequence and extracts the original camera's lens and motion parameters, allowing you to composite 2D or 3D elements correctly with reference to the camera used to film the shot. How to create Open Shapes with and without feathering for a detailed hair roto shot. 4. (you may apply as many as TimeBlur nodes needed to get the best result). For example, if you set the shutter value to 1 and your current frame is 30, the shutter stays open from frame 29 to 30. • to open the shutter at the time you specify, select custom. 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. It’s very important to keep the point consistent meaning if a point for example is on the tip of a finger, it should stay there for the entire frame range. I want to know more about motion blur in Silhouette, give me some tips or trick to get quick results.

VectorBlur expects the values from your input plates to be pixel space screen units, in other words one unit should be equal to one pixel. ROTOmotor is a leading producer of two and four stroke RC airplane engines. You might have files using varying values, particularly if you’ve used a third party application to create your input files. A look at creating a post motion blur effect using Motion Vectors from Cinema 4d in NUKE using Reel Smart Motion Blur (RSMB) from Impossible Engine’s Scott Oliphant who not only provides a great overview to the process, but also some tips.. quick overview of how we use RSMB motion vectors in nuke from a c4d motion vector pass Finally I just apply a small overall blur to soften the hard edges we end up with. In Nuke, apart from the default motion blur options inside the roto node, you can control the motion blur with feather quite easily but this sometimes involves you in doing a lot of frame by frame motion blur … For example, a value of -0.5 would open the shutter half a frame before the current frame. The following nodes under the Transform menu have their own controls for adding motion blur to transformations: These controls allow you to create motion blur without adding a separate node for it. You will learn how to setup a shot in nuke, undistort the plate, 3D camera track the scene, set up a 3D Composite with projections, colour correct sign elements, redistort elements, roto-mask a foreground actor, deal with motion blur, add camera artifacts, paintout details, add camera noise and output your work for feedback or Dailies. Reply. Camera Tracker for After Effects© allows you to pull 3D motion tracks and matchmoves without having to leave AE. To create the motion blur accurately, Silhouette calculates the distance that the points travel in each frame. 1. ... As you can see I had to take alot detail into account, For example the way the hair moves in the wind and the motion blur between the fingers when she is moving her hand. In this case, we know the motion vectors are not continuous, so selecting forward is a good option. With this setup, your ShuffleCopy node controls would look like this: • backward - backward method is effective and fast but may not be accurate if you don't have motion vector values at all pixels throughout the whole frame. When you have something like that (image above) to roto, suddenly there’s no visible edge, the direction of the motion could be misleading as the direction of motion blur is not always the same(depending on the shutter speed/angle), so it’s important to understand the tools you are working on. – REELSMART MOTION BLUR FEATURES FOR NUKE & SCRATCH automatic tracking of every pixel from one frame to the next variable amount of blur ability to blur one sequence using the motion from another. Many skills are required to become a good roto artists, I couldn’t imagine I would be excited to do a roto task because I knew this time I have new challenges! As discussed above, The Foundry led the pack in developing roto tools for dealing with stereo shot material. In this tutorial, you will create motion blur effect using the motion vector pass rendered from Maya and VectorBlur node. Connect the VectorBlur node to the ShuffleCopy node. I created a roto node and used the opacity to create a simple effect to have my CGI character look somewhat in the water. with the old planar track it was pretty simple. The After Effects Roto Brush tool is quick, simple, and a great option for getting some clean VFX rotoscoping done. but in occasions when the process gets very long and days passes by with making just a little progress, you start to feel a bit anxious!

This is the colour “smear” I refer to in the title. Edge blur, Edge blending and Edge ... composition. You’ll want to check the. So, in order to get a working motion blur result, you should make sure Nuke is getting correct values to work with. Shrink a copy of the mask to the point, where all the semi-transparent (blurred) edges are cut away. 9、为了求得正确的Motion Blur,在画面帧数范围之前和之后,ROTO应该多绘制几帧。 10、利用除了Nuke以外软件绘制Roto,例如Mocha pro对于形状规则的物体可以自动解算出Roto运动,Silhouette v5.0对于运动模糊的计算要优于Nuke。 Create a mask with a natural-looking motionblur, regardless of the background objects mixing with the hand. Track complex organic surfaces through occlusions and blur using Mocha’s intuitive layer based interface. - Roto of biker and bicycle using Nuke. The following is an example of creating motion blur with the VectorBlur node using files written from a third party application. Using the ShuffleCopy node, select which channels VectorBlur should read from your motion vector file (node input 1) and color image file (node input 2). When enabled, motion blur is applied to all shapes in the current Roto node. Getting a good, even motion blur result largely depends on selecting the right calculation method. So, in order to get a working motion blur result, you should make sure Nuke is getting correct values to work with. Roto and Match Moving in Nuke. You might have files using varying values, particularly if you’ve used a third party application to create your input files. With a good GPU, vector blur is much faster\nthan the default multisample motion blur within transform nodes.\n\nVector blur WILL NOT produce curved motion blur, so in some situations it\nwill look better to use another motion blur type if that is needed." For example, if you set the shutter value to 1 and your current frame is 30, the shutter stays open from frame 29.5 to 30.5. • to open the shutter at the current frame, select start. It’s also a great idea to make sure motion blur is selected in the Roto Brush parameters under the Effects Panel, so your edges will flow naturally if there’s a lot of motion in your subject.
