It's inherent to video that you "have to make up data" - if I tell you the barebones of something that happened in real life (we went to a doctor's appointment but discovered it had been scheduled earlier than we thought) - you may supply details that aren't "true" because you have to supply something to flesh it out - but you know you're supplying them!

If instead we make a video that conveys the same information; it has to "make up" details (we have to cast the actors, which will be of a certain age, sex, race, etc; we have to give them lines, etc; and so on) that may colour the implications - and you, as a viewer, have no easy way to determine what is essential and what is accidental.
