AE/SE Advanced Distortion Effect
Shows the use of SynthEyes's "Advanced Distortion" effect (pixel bender) in AfterEffects. This effect is able to reproduce the complex distortion types, including off-centering and high-order (fisheye) distortion computed by SynthEyes's lens-grid-based calibration tool.
Here we show the calibration being generated in SynthEyes, an Advanced Distortion node being set up as an undistorter in AfterEffects to undistort the original footage, then a second advanced distortion node being set up to re-distort the un-distorted footage---yielding basically the original image. This latter re-distortion effect is what you need to use the two-pass lens distortion workflow, to deliver distorted composited images as a final result to the client.
Requires the latest pixel benders as of 6 Jan 2012 --- available from the customer-only portion of our website. Footage from a GoPro HD.
