roto motion blur nuke

Getting a good, even motion blur result largely depends on selecting the right calculation method. PowerMesh enables a powerful new sub-planar tracking engine for VFX, roto and stabilization. - Applying zDefocus and Motion blur to the background to match foreground optical properties and get a macro lens effect. ROTO 125 FS. Nuke. Rotoscoping could be one of the least desirable things to do, but it is nevertheless one of the important steps in preparing a shot for the final comp. 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. â¢ to open the shutter at the current frame, select start. You also need to tell VectorBlur which motion vector channels to use, so change the, If your motion vectors have been normalized to be between 0 and 1, you can set the u and v values in the, If the vectors have been premultiplied with the alpha channel, their value is not accurate in places where the alpha is not 1.0. Also included is a plugin that allows you to blur with user-supplied motion vectors which, most likely, will come from a 3D animation system. Track complex organic surfaces through occlusions and blur using Mocha’s intuitive layer based interface. Meanwhile, the image file would output the red, green and blue channels for the main color image. Keying - Roto of biker and bicycle using Nuke. Join Steve Wright for an in-depth discussion in this video, Creating 2D motion blur, part of Nuke Essential Training (2014). The After Effects Roto Brush tool is quick, simple, and a great option for getting some clean VFX rotoscoping done. For example, a value of -0.5 would open the shutter half a frame before the current frame. Connect the VectorBlur node to the ShuffleCopy node. You might have files using varying values, particularly if you’ve used a third party application to create your input files. 1. Finally I just apply a small overall blur to soften the hard edges we end up with. One of hardest things to tackle in a roto work is getting the motion blur right. Roto and Match Moving in Nuke. 4. 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 modifications. Nuke uses this information to calculate the distance that one pixel travels between two frames. – 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. This is the colour “smear” I refer to in the title. 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 Amongst it’s good futures, calculating the right motion blur is extremely useful, there’s a little trick though!

In this case, we know the motion vectors are not continuous, so selecting forward is a good option. Basically, I faced problem several times when the shutter angle changed. - Regrain the background to match the foreground. Next we blur the image and then unpremultiply it. The next evolution of Mocha. 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. So, in order to get a working motion blur result, you should make sure Nuke is getting correct values to work with. Stage 2. label "This method is good for adding motion blur to any keyframed animation\nthat has a large bounding box. 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. Read in your footage and motion blur files, for example an .exr file with a spinning donut and a .sgi file with motion blur vectors that are normalized to have values between 0 and 1. I created a roto node and used the opacity to create a simple effect to have my CGI character look somewhat in the water. ... Roto masking examples .

(you may apply as many as TimeBlur nodes needed to get the best result). I have been trying to teach myself Nuke for the past few months, so when it came time to roto something that was moving with some blur, this became very important to me. â¢ 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. 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. Warped surface tracking and roto that sticks. To slove the motion blur problem we can use a technique called Feathering. Personally I find it ok, sometimes it’s exactly what you need! With this setup, your ShuffleCopy node controls would look like this: â¢ 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.

The following is an example of creating motion blur with the VectorBlur node using files written from a third party application. 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." 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!
