CameraTracker 1.0V5 Released
The Foundry has released an update for their superb CameraTracker plugin for After Effects. V5 features a slew of bug fixes. Details can be found here on the Foundry's website.
After Effect's built in 3D Camera Tracker is really nice but can't handle complex footage, lens distortion, and is lacking any tools for defining the ground plane. The Foundry's CameraTracker fixes all those problems and has a ton of other features. It is dead easy to learn and produces rock solid 3D tracks very quickly.
