Perhaps not, but I am not certain if “amateur” is the right word in describing the creator contents on YouTube. Certainly, we’re not talking Disney-level video quality, but most of the creators I follow appear to have some skill in AV recording and video editing. Plus, they do present some things that are of interest to a wide variety of audiences. Therefore, I don’t necessarily see such content as “amateur-created”. Now, that’s not to say there are no amateur-level content on YouTube. I’m sure there are plenty of contents that really are of poor quality and not worth your time and money.
Please be aware that I am not trying to convince you to jump onboard YouTube Premium. That’s your decision.
