more and more videos that we can see around, have a slow motion and fast motion applied (i thing i post). So we can see for example a drone above the city flying quickly, and slow down quickly to almost stop, then maybe resume flying quickly or at normal speed ... (three type of velocity in the same shoot!).
This is something we can make entirely in post but my question is: how can we properly shoot this sequences on set, to avoid motion blur and to have enough FPS to make e believable extreme slow motion... (and for many other VFX needs, like Keynig, match-moving...)?
Shortly, we should increase the shutter angle speed (and break the 180° shutter speed rule...) or augment as much as possible FPS (Depending on the camera's capabilities, of course)?
Or maybe both, but in which proportion?
I mean, the first idea could be to increase FPS to 50 or 60 fps (common DSRL in use). According with this frame rate, I should increase shutter speed to 100 or 120 to stay in the 180° shutter speed rule, if I'm right.
The problem is when you increase extremely the shutter speed, to 1/1000 and many more... in these cases you cant increase your frame rate... so what happen?
Of course, if you increase shutter speed, you underexpose and you have to compensate with Aperture or adding lighting. But without exposure problem, again, what happen if you increase shutter speed breaking 180° rule?
P.S. My question is concerning DIGITAL SHOOTING, no FILM.
Many thanks for a reply.
