Some folks who should know better have claimed - and continue to claim - that frame rates that divide mains frequency eliminate mains-related flicker. That would only be true if the mains electrical supply was genlocked to the camera.

Are you mixing two different issues? Synchronization would be necessary only if the exposure time was much shorter than the lighting cycle period; if the exposure time is exactly the lighting cycle period or light flicker period, then it does not matter at all what part of the wave the exposure begins at, because an entire wave period will be recorded, and exposure is therefore the same in all frames.

Beware of correct answers to wrong questions.
