I'm trying to lens de-warp some EPIC 5K footage shot anamorphically (don't ask!) with a 75mm PL. Unfortunately, a lens grid chart was not available during the shoot. And I'm having a devil of a time trying to manually undisort the footage so I can Mocha some elements in the background.
I've got the footage into After Effects with a custom pixel aspect radio of 1.76.
Totally shot in the dark question: Anyone shoot a lens grid calibration chart or checkerboard with this setup? I'd be in your debt if I could get a still image of that.
If that's not available, does anyone know the lens correction values for footage like this?
