That statement is correct, but without an inferior sauce to compare it to you can’t show other people. I’d rather not buy US for that.

Depends how long is long form for you, if you mean like multi hour videos I have less to give. But for like 25 to 40 minutes videos:

Practical engineering - educational videos about civil engineering.

Dr. Becky - space/astronomy news from an astrophysicist.

Plainly difficult - civil disaster documentaries

Joseph Anderson - gaming essays (multi hour)

Raycevick - gaming essays (around 30min)

The sphere hunter - game essays, mainly classic horror

Jay Foreman - British comedy.

LGR - retro tech deep dives, and tech oddware.

Joe Scott - Did you know, style investigations.

Plus some already mentioned. There is probably more, but keeping this shorter.
