You can set linear or narrow lens within the camera which will crop in and straighten the image. this will cause a slight decrease in quality but it will save you time in editing.
Most of video editing tools allow you to adjust this as well .
If it bothers you that much you chose wrong camera for the job.

 

Hello and welcome to the forum, as said above the easiest way is to use the lens correction in an editor.

You can do this in post, although depends upon your editor.
I use the MAC platform and FCPX.

Old video - but still what I use to date if I need to remove distortion:

 

As all of the above. you are shooting wit the sensorand cropping is done via camera software, Superwide, wide, Med Linear, Narrow these are the FOV, notice Med and zoom I given all the fov of all the camera's in one.

in the H7B set like said the FOV to Linear and the rest is Histor, or in post editing crop in a few Percentage
