Nuke training in China
fxphd invited me to spend 1 month in China teaching Nuke. It was a great experience!
Check out the details here
the FreezeSplineWarp technique
Hello! On this video I present the “FreezeSplinewarp” technique: it allows to matchmove and stabilize plates using Nuke’s splinewarp node.
With CornerPins your are limited to 4 points, but with this technique you can use any number of points, getting more finer control. I show also the scripts that I developed to automate the whole process.
Here are the links to download the python scripts for Nuke v7:

You can support the script development with Donations and also by emailing the Foundry’s support and request prioritization for the following ticket’s:
Bug 35393 – Unable to create splinewarp curve via python _curveknob.Shape
Bug 34896 – a way to join splinewarp shapes via Python
These will help to further improve the scripts and automation of the technique.
cmiVFX – Mocha Pro Advanced
My new training is ready! This time it’s covering advanced topics with Mocha Pro and After Effects: Digital Make-up and 3D camera solving (matchmoving)
http://www.cmivfx.com/tutorials/view/508/Mocha+Pro+Advanced
Chapter Descriptions
Introduction
Brief introduction about the topics that will be covered in the training.
Digital Make-up
Start of the digital make-up project, studying the shot. Initial Mocha Pro Project Setup, discussion about approaching the tracking of a non-planar surface. I compare the tracking options and result quality of the track and explore the tracking properties to facilitate the tracking process.
cmiVFX – Introduction to Rotoscope with Silhouette Roto and Paint
Another video training that I’ve produced is online on the cmiVFX website:
http://cmivfx.com/tutorials/view/327/Silhouette+Intro+To+Rotoscope
This time I worked on a rotoscope training covering the Roto Node of Silhouette Roto and Paint software.
Silhouette is my favorite rotoscope software, and I present not only software skills but also the needed rotoscope techniques to create great mattes.
Chapters Descriptions
Introduction
User Interface tour and overview, learn how to setup projects, sessions, and load media files. Explore the user interface layouts and performance settings that will affect footage playback and rotoscope speed.
Drawing Shapes
Extensive explanation about Silhouette’s shape types: b-splines, x-splines and bézier. Drawing techniques, using the reshape tool, adjusting curve tension and point modes: cardinal, corner, b-spline and center. Navigating the viewer with tools and shortcuts: zoom, pan.
Intro to Rotoscope
In depth review of the Project window. Discussion of strategies to break down subjects into shapes for rotoscope. Working with the Viewer modes and inputs to help on shape drawing, rotoscope evaluation and to avoid background color contamination.
Animating Shapes
Using the reshape and transform tools to manipulate shapes: moving, rotating, scaling, skewing, and corner pinning. Setting the anchor point and using special transform tool modes to manipulate groups of shapes and points. Planning the animation, optimal keyframe positioning in time and dealing with keyframing interpolation. Introduction to the “back and forth” technique.
Point Tracking
Review of the Object List: creating and manipulating layers. Techniques to create and use Silhouette’s excellent point tracker. Applying 1, 2 and 4 point tracking data to layers, refining problematic trackers, manipulating the transform matrix of layers and using the layer stabilization feature.
Planar Tracking
Use of Silhouette’s Planar tracker. Evaluating the planar tracker results. Pre-processing plates to improve planar tracker results. Extracting point trackers from shapes.
Finishing the Rotoscope
After learning the tracking techniques, the rotoscope continue and the project is finished. Discussion of other useful rotoscope techniques, tips and tricks: Using the Multiframe tool, animating shape opacity, layer stabilization, extracting trackers from shapes, breaking keyframed shapes into smaller pieces.
Hair
How to deal with hair and other thin rotoscope subjects. Working with open shapes and stroke width. Open shapes drawing techniques, and manipulating/animating complex groups of shapes.
Rendering
Rendering the mattes to be used on any compositing software. Discussion of render settings and node parameters that affect the render output. Rendering Slap Comps for previews and dailies.
Exporting Shapes
How to export shapes from Silhouette. Detailed export/import overview to After Effects, Nuke and Shake. Using Silhouette Actions.

Mocha Pro Training Set produced for CmiVFX
I have produced recently an Imagineer Mocha Pro training set for CmiVFX, covering all the software modules. It is the first Training available in two languages on the CmiVFX website, featuring English and Portuguese!
PS: I would like to thank the folks of Trilhas Urbanas Estudio that allowed me to use their facilities to record the training audios. You guys rock!
Mocha Pro For Production Volume 1
Introduction
Since this is the beginning of a video series, we will get started with planar tracking concepts. You’ll get a guided tour of the Mocha Pro user interface, utilizing a simple project setup. You’ll use the Tracker Module to track surfaces, discover strategies to improve tracking, track surfaces that leave the screen, learn about the types of splines layers shapes and how to review the tracking quality with the Viewer controls.
Rotoscope
Learn how to use the planar tracker to achieve faster results when doing Rotoscope. There will be an overview of the tools to create and manipulate Layer shapes, including edge feathering and smoothing. Learn how to evaluate rotoshape quality with the Viewer controls and when the rotoscope is finished, explore the options to export the results to other softwares.
Advanced Tracking
While working on a more challenging project, you will learn how to isolate unwanted elements from the tracking area using garbage mattes and Blend modes. Then watch a more in-depth explanation of the Adjust track module to further refine your tracking results when the Track module is not enough to solve the tracking. We then break down several methods of exporting and importing into other 3rd party applications, such as: Final Cut Pro, Nuke, Motion, and After Effects. (Autodesk Flame customers can review our Flame training video for GMask information)
Insert Module
Discover how to use the Insert module parameters to successfully place images on tracked surfaces. Learn how to render final composited inserts from Mocha Pro or to export the insert layer for other softwares. Lens Module Explore the Lens module to obtain better results on the other Mocha Pro modules when shots have lens distortion. (In photography, distortion is particularly associated with zoom lenses, particularly large-range zooms, but may also be found in prime lenses, and depends on focal distance)
Remove Module
With the two example projects presented, understand how to use the unique Remove module of Mocha Pro to eliminate unwanted elements from shots. Using the same scene background or additional clean plates, we discuss the removal parameters in depth, making it easy to remove unwanted objects in shots requiring enhancement.
Stabilize Module
In this section we show you how to take shaky footage and make it presentable for further post production. Learn how to recover the missing parts of the plate using the Border settings and how to further smooth Camera movements using the Stabilize parameters.
