Everything that goes onto youtube (unless an advert) is a story, not everyone understands this. Some are entertaining, others informative (or a bit of both) and then there are the ones that are just junk. Right now TTT channel is falling under junk.
A good editor follows the story as dictated by the director, who in this case would be Tim or Jenn. If they don't want any of the crap that they keep letting slip by on the videos, it won't go on there. Editors have style but do not control the narrative unless they want to be fired.
What they should get by using a professional editor is a story that people will want to see, verses these home movies.
Keep in mind even the best editor cannot create content where there is none, nor can they fix bad photography (there are a few tricks they can employ).
