And he's wrong.
Information from Youtube presenters is just as likely to be incorrect as opinions of forum members and some individual FAA personnel.
At 9:47 he says:
If you say I'm going to fly out there to put my footage on Youtube so that everybody can see it, then all of a sudden you are no longer flying for fun.
Now your intent is to put the footage on social media, it's no longer recreational flying.
... now you need to have a Part 107 certificate.
His opinion about this is incorrect.
Here's the official position of the FAA (not misguided opinions that some FAA staff occasionaly give)

Note the part I highlighted in red.
B. Aviation-Related Videos or Other Electronic Media on the Internet. UAS videos, in particular, are increasingly appearing on the internet. UAS videos may depict aircraft being flown in a variety of classes of airspace and at varying altitudes. Inspectors are to follow the protocol below when receiving notification of videos with potentially noncompliant UAS operations posted to the Internet.
C. Evidence. In all cases, the FAA must have acceptable evidence in support of all alleged facts in order to take legal enforcement action. Inspectors are reminded that:
1) Electronic media posted on the Internet is only one form of evidence which may be used to support an enforcement action and it must be authenticated.
2) Electronic media posted on the Internet is ordinarily not sufficient evidence alone to determine that an operation is not in compliance with 14 CFR. However, electronic media may serve as evidence of possible violations and may be retained for future enforcement action.
3) Inspectors have no authority to direct or suggest that electronic media posted on the Internet must be removed.
NOTE: Electronic media posted on a video website does not automatically constitute a commercial operation or commercial purpose, or other non-hobby or non-recreational use.
