Claim:
1. A method of modeling lens distortion for a camera lens used to capture video of an event, comprising: (a) selecting a lens distortion curve, the lens distortion curve including a plurality of camera lens distortion parameters, wherein calibration of the camera lens using calibration targets is not performed; (b) generating a camera model based upon the lens distortion curve; (c) integrating one or more first virtual insertions onto the video using the camera model; and (d) applying a correction factor including scale, offset and curve gain to the one or more camera lens distortion parameters to adjust the lens distortion curve, wherein the correction factor is determined based on a realistic appearance of the virtual insertion with respect to the video, wherein the realistic appearance is when the virtual insertion appears to be rationally integrated onto the video to a remote viewer.
