| Distort > Optics Compensation is intended for removing and reintroducing distortion. It's fairly straightforward and requires you to adjust the properties manually as it does no analysis of the footage. This is usually easiest to do on footage that should have strong
vertical or horizontal lines in it. You can put a layer with the grid
effect above your footage to guide the process. Once you have the properties all set for your undistortion, you'll need another copy of the effect applied after compositing (on an adjustment layer, or up a comp level) with the "Reverse Lens Distortion" checkbox enabled in order to redistort the footage. Other than that I know that The Foundry's CameraTracker has some lens distortion features that will analyze a sequence and generate data on distortion that can be used to undistort/redistort. There's at least one free tutorial on using that feature: http://www.thefoundry.co.uk/products/cameratracker/training/#class8 -D On Fri, Jun 29, 2012 at 8:46 AM, Byron Nash <byronnash@gmail.com> wrote: Apparently no one using AE removes lens distortion. ;-) |
