In VP a good match between real footage and CG elements is very important.
Like said at 14:02 of this presentation:
Is a there a simple way to send real camera lens distortion data to UE4 camera ?
What kind of tool should I use to extract real camera lens calibration data ? OpenCV ? ST Map ? From a Fov calcultor like this one Camera Field of View Calculator (FoV) ?
How could I send these calibration data to UE4 ?
Is there a tutotrial or a guide somewhere to do that in a straightforward way ?
