How does Sony fx 1000e camera shoot a blurred background? Mainly interviews with people. Hope is an experience, not a pure copy.

Simply put, the aperture is adjusted to the maximum and the background is far-reaching. Sharpness will decrease.

There is also a long focal length and the aperture is also adjusted to the maximum. The sharpness is not only reduced, but also the deformation is enlarged. The deformation of the wide-angle end is generally outward convex, and the deformation of the telephoto end is inward contraction.

Mainly depends on your lens MTF~

Movies are usually shot with a large aperture fixed focus lens, which generally cannot achieve that effect.
