Yes, for most of my typical corporate or documentary green screen stuff it's not an issue - and for someone sitting or standing and talking at 30fps a shutter speed of 1/60 or 1/80 produces great results with Delta Keyer in Resolve/Fusion. But in cases like that there's very little motion blur to deal with - maybe some hand movement or a bit of wispy hair - and this can be dealt with fairly easily. Lately I've been playing with adding a Glow node (set very low) after the Merge -- to smooth older skin tones/details a bit and take the curse off the 4k sharpness - since on a lot of shoots since Covid the subjects (or company policies) have eliminated full makeup.
But one specific shoot comes to mind where the motion blur without a faster shutter was crazy -- a full height shot with two cheerleaders doing 'jump splits' (I don't know what you call the move??) with pom-poms and their long hair moving all over the place. But you get the idea... The 30p (1/60th) blurs from a 'normal' camera were a nightmare -- but the 120p footage from the slow motion camera (w/180 degree shutter) proved a better option for us, even when brought to normal speed by frame skipping.
