Everyone watches cutscenes in their own speed since you know some people read again etc. and you have to usually actually click to make it progress. So for me it could take an hour and for you maybe 10min.

BUT SERIOUSLY IF IT BOTHERS YOU JUST SKIP THE CUTSCENE AND WATCH IT IN AN INN LATER. Not that hard cause they are not unskippable, every cutscene that has this message is as far as my knowledge goes one you can skip. So i dunno what you are up about but sure.

I leveled 20 alts through the story up to Endwalker and i can tell you you can skip most cutscenes and those you can't skip are over in some minutes, if you can't bring up some time when the message comes up then well don't do the msq. Or leave for whatever you will be so busy with and leave the game running, the cutscene usually won't run away.
