Superpose is a plugin from Keller Software for The Foundry’s NUKE and Adobe After Effects that automatically cleans up backgrounds and removes unwanted foreground objects. It does this by statistically analyzing each pixel and recreating the background behind moving objects in an image sequence or video clip. It is not meant to create a perfect, end result but can create very good results. 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.

This semester at college I am doing a series of weekend projects. I am about to begin the second project in that series, which will be a simple test of slow-motion and some CG integration. I started my first project in January, but that post is still coming.
