Video Format

Dear, good morning.

It happens to me that sometimes my camera uses the entire width of the frame and sometimes it assumes the width as the one of the attached image.
I marked in red the sides that it sometimes cuts out.

I have detected that using the notebook’s camera it occupies the entire nacho, but using the webcam connected to the docking station, sometimes it takes the entire width and sometimes not (as in the attached photo).

I will appreciate guidance for this case.
