ITs Art has an a great collections of behind the scenes of some of the Best Visual Effects Work from Studios around the world. Check it out at – http://www.itsartmag.com/features/verybestofvfx/
At facilities Sometimes a comprensive tools set is provided for the job that is at hand, for example they may only have moca for after effects and Nuke 6 instead of X leaving planar tracking out of the picture in times where you may desperatly need it.
Or You may want to take avantage of PF Tracks 2011-2012 Robust user Tracks for a rotation and Skew heavy shot.
Well here are two tools I use, that exist in the cloud and are ready for you right now.
Multi Resolution Bicubic Transforms/deformations on 3D cards and 2D transforms. Intelligent 2.5D Relighting paint tools, A Instanced Brush tool that duplicates user input in multiple offseted locations. Improved nondestructive Workflow( All Transforms made modular), Nondestructive HSV or other Algorithmic based Key masking. Nondestructive True vector Pen tool Shapes (useful for masking), Pen tool vector point feathering. Improved Camera Raw workflow (enable Camera Raw as a standalone product and improved hooks from photoshop back out to it.)
Adobe, if you do not feel these features are suitable for the ‘every mans’ photoshop , even though Photoshop eliminates aims to do that, Provde a Photoshop Pro Product
Smooth surfaces, to some of us who religiously do Feature Tracked 3D Camera solves, they are the Devil. Unless the smooth suface has pours that we can boost the contrast on, its pretty hard to track those suckers. Something that Planar tracking seems to Excel at. By Planar Tracking a smooth surface suddenly allows you to recreate the shot to have a texture on top of the of this surface, But what should you put on it? A gird would seem to work out great..since it would allow a high density of trackers constantly distributed over the surface, In theory its sounds good. Yet Grids are too similar for the tracker algorithm, which bumps up the computational time to figure out which grid square a track as well as confusing the features to jump from square to square with in the search region a set back that often cant be avoided if the track is moving a significant distance. So what to do? An Irregular Texture turns out to be just what the doctor ordered. Perln Factual Noise is a fast way to generate a texture on the fly And complimentes most trackers search algorithms natural ability to look for high contrast patterns through out the enhanced plate.
The Exeption: Optical Flow tracking
Where contrast based Feature tracking gets confused and dazed at a black and white checkers Optical flow behaves different and tracks through less of an issue though it will get tripped a bit.
Nuke was made for stereo. Even before its support in version 5 Nukes flexible node sytem seems
to be the perfect way to cobble together a way to make any thing go which way.
But if your in a pinch or are new to stereo Making your own custom rig may seem like a Daunting Task.
So here is mine, I hope you have fun with it.
Under The Rig Control node
This Node Controls the Rigs Movement
Key frame or Parent a Solved camera to the RIg.
For cameras with Variable Focus you Can parent the rigs focus controls under the Solved Import tab.
Enjoy The ability to nondestructive adjust the camera on top of a monoscopic solve data
Toe Slider- to adjust convergence – Leave at 0 if you want a parallel rig
Inner Axeal – Also Known as Inner Ocular when Refuting to the Human Eye, Slides both cameras away and towards each other horizontally.
Rig move – this is a quick peak where the axis is sitting and gives you the ability to parent the rigs position
— Indie Tab
Left Indie – moves the Left camera Independently from the Right non destructively to the inner ocular
Right Indie – Moves the Right camera Independently from the Left non destructively to the inner ocular
Left Rotation Indie – Nondestructive Rotate the Left
Right Rotation Indie – Nondestructive Rotate the Right
This is the same as what you would find in the Camera Projection Tab, Adjust the Focal, Aperture ect
Organizing your Nuke script can be tricky, allot of things overlap input if you don’t plan your script out right.
If your not familiar with the “.” key I would suggest you make it your new best friend, Open up nuke hover over the Node Graph and Hit and hold it.
Before your eyes the Round Node path connectors called “dots” will Manifest over and over again, you might not need this many. ..But start your First Read Node out with 3 of them to start out with.
To add additional dots to a stream of nodes hold down the option key to have the mid points of the connections light up, then select where you want it to go.
A quick tip useful for any heavy Nuke User is how to find a Node you created in a complex Node Graph.
By hitting “/” while hovering over the Node Graph
Proms a Search window where you can type in and search your to your hearts content.
Now combined with the tab menu you’ll be blazing away through your comps like a pro.

Toxik or should I say Composite saves out allot of the user experience to its preference file. This is great if you like it a certain way. But with All the ways you could change something that you cant figure how to put back…this could have you up a wall trying to figure out what went wrong.
For those of you frustrated compositors here is the quick fix you been craving.
For example for OSX Toxik 2011 Users:
It is to be notied for you Studio artist you can inter changeable save out your preferences and link to them with in the project preferences.
With in the UI you can find it under
Edit/ Project Preferences, Under the first tab that is displayed the Information tab
Most of the time I’m keen on sharing a Visual effects tip that I had to rack my own brian out trying to solve, but this time I would like to give the air waves for a brief moment to a photoshop plugin thats comes in really handy for me, Golden Crop. Golden Crop Does math mathematic operations to give you Complex Composition models and algorithm in simple photoshop guidelines.
For those of you who are new to installing photoshop plug ins, simply drop the plugin file into your photoshop plugin folder, OSX users will find this in their photoshop folder in the application folder.
Once downloaded your going to search high and low in photoshop and wonder what actualy happen, dont worry I had the same reaction after Installing Golden Crop, and its where you least expect it. In the File<automate menu will apear a new set up options for Golden Crop, Simply select what operations you want it to execute and there you go.Compostions no one can argue about with you, because you have science your side. Or at least Golden Crop.
