Imagineer Systems, makers of popular planar tracking software mocha, have released a new training video with product specialist Mary
Poplin, comparing mocha with the new Adobe Mask Tracker. The Mask Tracker works by drawing a mask and then telling After Effects to track the area within the mask. Mary discusses many of the pitfalls and limitations in the new Mask Tracker; however, it is also pointed out that the tool works adequately for tracking some objects, mainly rigid surfaces.
My personal conclusion is that the Mask Tracker is a quick-and-dirty, yet inflexible, tool for simple planar tracking tasks with limited movement. Despite its limitations, however, this may be a tool with yet unrealized potential and one that Adobe may develop further.
As I finished up my undergrad degree and my student job managing 3D printing for Huntington University, I was asked to set up a new 3D printer, the Form 1 from Formlabs. The Form 1 is a 3D printer that uses the photolithography technique to harden resin in micro-thin layers and was supposed to be much superior to our Makerbot Replicator. The Form 1 is better in many ways, but it has drawbacks also.
The Foundry, along with shots, has posted a new webinar that provides insight into the strange world of visual effects. Continue reading
Digital-Tutors has published an excellent introductory guide to The Foundry’s NUKE. The guide gives a very basic interview to NUKE compositing, and the basic steps of creating a simple composite. With its strongly beginner-oriented approach, this article accomplishes its stated goal of making this powerful software appear less-intimidating to first-time users well.

Premultiplication and unpremultiplication are essential concepts for any compositing artist to master. Premultiply refers to performing a multiplication operation on the alpha and color channels of an image. Unpremultiplying then, refers to dividing the RGB image color by the alpha. Without the proper use of these techniques, edge artifacts and/or incorrect color correction can occur. Continue reading
