I'm working to implement CGI elements to a short film using an Anamorphic Lens. The distortion off these lenses are quite beautiful but I am running into issues with cut-offs after implementing with Blender.
After distorting the footage from found K1, K2, K3 values, I am noticing that you lose alot of information on the sides of the footage when undistorting. Is there another approach to implementing CGI if you wanted to the elements to be at the edges of the frame without the shown cutoff?
Do you have any suggestions for this fix?

Footage and Undistortion
UPDATE: I did the lens distortion values manually using a grid for alignment. This shouldn't effect the need for these edges being cut off. The only way I can think of saving these edges is by putting a black border around the video, re calibrating the K1, K2, K3 and then undistorting, giving more room on the sides for edges. There must be a simpler way though.
