It's called "shutter angle," see e.g. [https://www.red.com/red-101/shutter-angle-tutorial]. The angle, as a fraction of a full circle, is the fraction of the shutter time that the frame is exposed to light. Larger shutter angles give more motion blur, and smaller angles give a more stroboscopic effect.

When shooting on real film, an obvious complication is that the set lighting has to be well-balanced for the chosen shutter angle. A dim scene can't easily be shot with a small shutter angle, and a bright daylight would overexpose a large angle.

Special effects, including postprocessing trickery, are almost the opposite. The default state of a render is to be perfectly sharp and to exist outside the flow of real time, and both focal and motion blur are deliberate additions.

Digital sensors are in theory compatible with arbitrary "shutter angle" equivalents, but your phone's video camera is more likely to set the shutter speed as necessary for auto-exposure.
